Abstract

Five main facies of deep-water clastic rocks can be defined: classic turbidites, massive sandstones, pebbly sandstones, conglomerates, and debris flows (with slumps and slides). The classic turbidites consist of monotonously parallel-interbedded sandstones and shales without channeling; internal sedimentary structures include grading, parallel lamination, and cross-lamination. Massive sandstones are thicker, coarser, and commonly channelized. They lack the sedimentary structures of classic turbidites, but do contain evidence of dewatering during deposition. Pebbly sandstones tend to be well graded, and can contain parallel stratification and large-scale cross-stratification. Conglomerates are characterized by inverse and normal grading, parallel and cross-stratification, and commonly have a preferred clast fabric (imbrication). Both the pebbly sandstones and conglomerates commonly are channelized. The facies can be fitted into a model of submarine-fan deposition. Modern fans are subdivided into an upper fan (suprafan), characterized by (1) a single deep channel with levees, (2) a middle fan, built up from suprafan lobes that periodically switch in position, and (3) a topographically smooth lower fan. The suprafan lobes have shallow, braided channels on their inner parts, but the outer suprafan lobes are smooth, and grade basinward into the smooth lower fan and basin plain. The smooth suprafan lobes and lower fan are characterized by deposition of the classic turbidite facies, and the braided part of the suprafan lobes by massive and pebbly sandstones. When one lobe is abandoned and another starts to prograde elsewhere, the first lobe is blanketed by mud, forming a potential stratigraphic trap. The upper-fan channel is an area of coarse sediment deposition, or conglomerates where gravel and boulders are supplied to the basin. During fan progradation, thickening- and coarsening-upward facies sequences can be formed in a manner analogous to those of deltas. Fan channels also can be abandoned progressively, forming thinning- and fining-upward sequences similar to those of fluvial or distributary channels. These sequences can be identified on electric logs. Where basin shales act as hydrocarbon-source areas, the classic turbidites can act as conduits, leading the hydrocarbons to the thicker, laterally coalesced massive and pebbly sandstones of the braided suprafan lobes. These bodies can be of the order of 25 km in diameter, and up to 100 m thick. The coarse deposits of the upper-fan channel also might form good reservoirs, being bounded by shales (levee deposits) on either side, and possibly by shales above if the fan-channel system is abandoned. Such channels can be tens of kilometers long, several kilometers wide, and a few hundred meters deep. Reservoirs may be present in all of these environments.

    abstract = "Five main facies of deep-water clastic rocks can be defined: classic turbidites, massive sandstones, pebbly sandstones, conglomerates, and debris flows (with slumps and slides). The classic turbidites consist of monotonously parallel-interbedded sandstones and shales without channeling; internal sedimentary structures include grading, parallel lamination, and cross-lamination. Massive sandstones are thicker, coarser, and commonly channelized. They lack the sedimentary structures of classic turbidites, but do contain evidence of dewatering during deposition. Pebbly sandstones tend to be well graded, and can contain parallel stratification and large-scale cross-stratification. Conglomerates are characterized by inverse and normal grading, parallel and cross-stratification, and commonly have a preferred clast fabric (imbrication). Both the pebbly sandstones and conglomerates commonly are channelized. The facies can be fitted into a model of submarine-fan deposition. Modern fans are subdivided into an upper fan (suprafan), characterized by (1) a single deep channel with levees, (2) a middle fan, built up from suprafan lobes that periodically switch in position, and (3) a topographically smooth lower fan. The suprafan lobes have shallow, braided channels on their inner parts, but the outer suprafan lobes are smooth, and grade basinward into the smooth lower fan and basin plain.

Abstract

Deep-water siliciclastic reservoirs are a major high potential play. As of December 1994, more than 170 wildcats have been drilled in the deep-water Gulf of Mexico with thirty announced discoveries. Already more than 2.2 BOE have been discovered in deep water gravity-flow sands of Gulf of Mexico slope basins. The initiation of subsalt exploration adds importance to understanding deep-water sands, because most of the potential reservoirs will be of gravity-flow origin. Additionally, recent large deep-water sand discoveries in the Paleogene of the North Sea and in the Tertiary of the western submarine slopes of Africa demonstrate the continued worldwide applicability of the turbidite play. This SEPM Core Workshop 20 on Turbidites and Associated Deep-Water Facies has been assembled to examine the sediment and rocks deposited within eight slope basins of the Gulf of Mexico. Turbidite is the most common word used to describe the sediment and rocks cored, but careful reading demonstrates that slumps, debris flows, high-density and low-density turbidites, and bottom-current reworked sediments are all recognized. These data sets are the focus of this SEPM Core Workshop and form the basis for evaluating different existing models and formulating new models for deposition of the deep-water Gulf of Mexico sands.

55. Morganti, John Michael, 2010, The Geology and ore deposits of the Howards Pass Area, Yukon and Northwest Territories : the origin of basinal sedimentary stratiform sulphides deposits: University of British Columbia.

Abstract

Economically important sedimentary-type stratiform Zn-Pb deposits exist in the Lower Silurian basinal facies of the Selwyn Basin along the Yukon-Northwest Territories border. Three major similar deposits have been defined to date, and are referred to collectively as the Howards Pass deposits. The Pre-Mesozoic history of the Howards Pass area was dominated by three major basin systems. During the Late Hadrynian to Early Cambrian the 'Grit Unit' was deposited as a clastic wedge with a western source area. Initially deep water turbidites were deposited but continued filling in of the basin led to shallow water deposition. During the Late Cambrian to Early Devonian the Rabbitkettle and Road River groups were deposited in the Selwyn Basin. The Selwyn Basin is defined by shallow water carbonates on the east and a general deep water environment to the west. The carbonates were succeeded by hemipelagic and pelagic organic-rich sediments with occasional terrigenous material deposited by geostrophic currents. Within the Selwyn Basin the Ordovician to the Early Silurian Howards Pass formation contains three major facies from east to west; a slope facies, a base of slope facies and a chert basin facies. The Howards Pass deposits occur in sub-basins in the base of slope facies. The third major basin system in the region was associated with uplift to the west and is represented by the Earn Group. In this later basin turbidity currents associated with submarine fans deposited clastic material derived from the uplifted centre of the Selwyn Basin and underlying rocks. Major barite deposits occur in the Earn Group. The individual Howards Pass deposits consist of complex saucer shaped bodies containing laminated to massive sulphides occurring in the Lower Silurian active member of the Howards Pass formation. The deposits are characterized by simple sulphide mineralogy, predominantly sphalerite, galena and pyrite. The sulphides in the deposits may be divided into six textural types which aid in characterizing the sulphides geologically and metallurgically. Types I, II, and III consist of laminated sulphides, types IV and V consist of laminated to massive sulphides and type VI consists of late diagentic concretionary sulphides. Types I thru V are associated with specific lithofacies in the active member. The Howards Pass deposits show characteristics common to stratiform-sedimentary deposits such as conformity with bedding, no obvious association with volcanic rocks, similar age of the three major associated deposits, single-stage Pb isotope systematics and association with organic-rich sedimentary rocks. In contrast differences between the Howards Pass deposits and other stratiform-sedimentary deposits, include deposition in a starved basin sedimentary environment, a lack of any associated feeder zone within 10 km, a lack of massive pyrite associated with the deposits, relatively low Ag and Cu associated with the deposits and a lack of bedded barite near the deposits. This datum suggests that the Howards Pass deposits are unique, and therefore a model is proposed which is relevant to the geologic setting. The most important part of the model is the synsedimentary deposition of Zn and Pb sulphides within sub-basins occurring at the base of slope of the eastern edge of the Selwyn Basin. The formation of biogenetic sulphide from sea water sulphate is suggested by the sulphur isotope data. This data also supports the existence of an ideal cycle of the active member and suggest a possible sub-basin evolution during an individual cycle. The origin of the metals in the deposit is not clear, but the association of volcanic tuffs near the shale-out at the eastern margin of the Selwyn basin suggests that warm fluids may have been expelled onto the sea floor, migrated down slope and collected in the topographically low sub-basins, or possibly compaction fluids may have been expelled directly into the sub-basins and concentrated during brine evolution. The abundant evidence for slumping and later folding and the possibility of both ordinary and more radiogenic Pb leads to the conclusion that post-depositional mobilization of both sediment and sulphide was important in the final location of Zn and Pb. Exploration for Howards Pass-type deposits, based on the above model, should emphasize the sedimentary nature of the deposits.

    abstract = "Economically important sedimentary-type stratiform Zn-Pb deposits exist in the Lower Silurian basinal facies of the Selwyn Basin along the Yukon-Northwest Territories border. Three major similar deposits have been defined to date, and are referred to collectively as the Howards Pass deposits. The Pre-Mesozoic history of the Howards Pass area was dominated by three major basin systems. During the Late Hadrynian to Early Cambrian the 'Grit Unit' was deposited as a clastic wedge with a western source area. Initially deep water turbidites were deposited but continued filling in of the basin led to shallow water deposition. During the Late Cambrian to Early Devonian the Rabbitkettle and Road River groups were deposited in the Selwyn Basin. The Selwyn Basin is defined by shallow water carbonates on the east and a general deep water environment to the west. The carbonates were succeeded by hemipelagic and pelagic organic-rich sediments with occasional terrigenous material deposited by geostrophic currents. Within the Selwyn Basin the Ordovician to the Early Silurian Howards Pass formation contains three major facies from east to west; a slope facies, a base of slope facies and a chert basin facies. The Howards Pass deposits occur in sub-basins in the base of slope facies. The third major basin system in the region was associated with uplift to the west and is represented by the Earn Group. In this later basin turbidity currents associated with submarine fans deposited clastic material derived from the uplifted centre of the Selwyn Basin and underlying rocks. Major barite deposits occur in the Earn Group. The individual Howards Pass deposits consist of complex saucer shaped bodies containing laminated to massive sulphides occurring in the Lower Silurian active member of the Howards Pass formation. The deposits are characterized by simple sulphide mineralogy, predominantly sphalerite, galena and pyrite. The sulphides in the deposits may be divided into six textural types which aid in characterizing the sulphides geologically and metallurgically. Types I, II, and III consist of laminated sulphides, types IV and V consist of laminated to massive sulphides and type VI consists of late diagentic concretionary sulphides. Types I thru V are associated with specific lithofacies in the active member. The Howards Pass deposits show characteristics common to stratiform-sedimentary deposits such as conformity with bedding, no obvious association with volcanic rocks, similar age of the three major associated deposits, single-stage Pb isotope systematics and association with organic-rich sedimentary rocks. In contrast differences between the Howards Pass deposits and other stratiform-sedimentary deposits, include deposition in a starved basin sedimentary environment, a lack of any associated feeder zone within 10 km, a lack of massive pyrite associated with the deposits, relatively low Ag and Cu associated with the deposits and a lack of bedded barite near the deposits. This datum suggests that the Howards Pass deposits are unique, and therefore a model is proposed which is relevant to the geologic setting. The most important part of the model is the synsedimentary deposition of Zn and Pb sulphides within sub-basins occurring at the base of slope of the eastern edge of the Selwyn Basin. The formation of biogenetic sulphide from sea water sulphate is suggested by the sulphur isotope data. This data also supports the existence of an ideal cycle of the active member and suggest a possible sub-basin evolution during an individual cycle. The origin of the metals in the deposit is not clear, but the association of volcanic tuffs near the shale-out at the eastern margin of the Selwyn basin suggests that warm fluids may have been expelled onto the sea floor, migrated down slope and collected in the topographically low sub-basins, or possibly compaction fluids may have been expelled directly into the sub-basins and concentrated during brine evolution. The abundant evidence for slumping and later folding and the possibility of both ordinary and more radiogenic Pb leads to the conclusion that post-depositional mobilization of both sediment and sulphide was important in the final location of Zn and Pb. Exploration for Howards Pass-type deposits, based on the above model, should emphasize the sedimentary nature of the deposits. Regional stratigraphic exploration should be aimed at defining major, platform-marginal, starved basins. The importance of defining the paleogeography, such as the base of slope and specific sub-basins, appears to be critical. This method emphasizes the petroleum methodology of looking for traps, although in the present case these are paleogeographic sulphide traps.",
