Abstract

Under consideration are the composition, structure and depositional environments of the Upper-Riphean Dzhura Reef Formation in the southeastern Yenisei Ridge. It was shown that a carbonate platform with reef-like stromatolithic rim structures has been formed in the Dzhurian time. It turned into a deep basin northward. It was shown that the evolution of the Precambrian carbonate platform was of cyclic nature and transgressive trend, which are similar to those of Phanerozoic homologues.

Abstract

Analysis of rocks of sedimentary formations and their settings has shown that there are two large sedimentation cycles in the development of the Riphean (up to Oslyankian) basin in the eastern zones of the Yenisei Ridge: Late-Penchenga — Early Pogoryui (R1-2) and Late Pogoryui — Mokryi (R3). Mass accumulation of gravities took place throughout the first cycle during the initial period under the rifting environment. Later the eastern part of a thick wedge of hemipelagic, fluvial, gravitation deep- and shallow-water shelf deposits of the passive margin was formed in the large basin. During the second cycle, the sediments were accumulated in the marginal basin, where chiefly carbonate platforms were formed in its near-continental zone (Kamenka zone), while basin and slope gravities and hemipelagites were formed in the Gorbilok zone. Shelf settings dominated during the final period of the cycle in the basin.

Abstract

Structure and rock composition of the Isakovka ophiolite belt within the northwestern part of the Yenisei Ridge were considered. Oceanic and island-arc tectonically related allochthon complexes covering continental margin of the Siberian platform were distinguished. Metaperidotites, metagabbros, tholeiitic basalts and volcanics of calc-alkalic metarhyolite-andesite-basaltic series were characterized geologically, petrologically and geochemically. Using Rb-Sr method we defined for the first time the upper age boundary for ophiolitic metagabbro — 1262±100 Ma. The possible age of obduction for oceanic and island-arc complexes is 600–620 Ma.

Abstract

The Yenisei Range and the adjacent territories in the east are subdivided into (1) the Mid-Angara intracratonic depression; (2) the Yenisei pericratonic trough; and 3) a marginal oceanic block, the Isakovka-Predivinsk area. The lower part of the Riphean succession is subdivided into two principally different sedimentary complexes — the Lower Sukhoi Pit Subgroup and the Upper Sukhoi Pit Subgroup (the Pogoryui-Alad’in interval of the succession). The fundamental nature of the events that separate these two complexes and the characteristic, rhythmically bedded structure of the Upper Sukhoi Pit Subgroup allow the latter to be ranked a separate straton, the Bol’shoi Pit Group. Its lower boundary is associated with the Grenvillian events commencing with the emplacement of the Teya granite-gneiss domes and other intrusive complexes dated at 1100–1000 Ma. In the sedimentation record these events are manifested as a sudden change from the slate complex, for which we keep the name Sukhoi Pit Group, to the rhythmically bedded succession of the Bol’shoi Pit Group. The latter is interpreted as a product of uproofing of an elevated hinterland to the west. Insofar as the amplitude of this elevated area decreases progressively toward the Mid-Angara trough, the Bol’shoi Pit erosional unconformity and the associated interval of nondeposition are absent from the area. In the west of the Yenisei Range, in contrast, there is a major stratigraphic gap in the sequence, which is associated with the aforementioned events. The hypothesis on intensive events separating the deposition of the Bol’shoi Pit Group of the Kerpylian Horizon and the Tungusik Group of the Lakhandinian Horizon is not supported by the new data. The change from carbonate facies into siliciclastics in the west was misinterpreted as an erosional unconformity, with basal deposits corresponding to the lower boundary of the Tungusik Group. The occurrence of the Upper Tungusik deposits overlying much older rocks is a result of the pre-Bol’shoi Pit erosion and the gradual expansion of the Tungusik transgression. Thus, there are no grounds to argue for significant pre-Lakhandinian events in the region. Hence, the Kerpylian and Lakhandinian in the Yenisei Range, as well as in other parts of the Siberian Craton, constitute two parts of a larger supraregional straton, which corresponds to the lower half of the Upper Riphean and is designated here the Mayanian. The fundamentally different nature of the events associated with the next, Baikalian stage of the development allows its tripartite subdivision in the region. Deposition of the Lower Baikalian (the Oslyanka Group) was preceded by the crustal extension at the junction between the continental and oceanic blocks and, possibly, the formation of one of the Yenisei Range ophiolite complexes, followed by the emplacement of the Tatarka-Ayakhta batholiths at around 850 Ma. Fragments of both complexes are found as clasts in the basal conglomerates of the Middle Baikalian Chingasan Horizon. The specific character of the pre-Baikalian events determines their apparently poor expression in the sedimentation (weaker metamorphism of the Oslyanka deposits compared with the Tungusik Group). Even the activity leading to the formation of the Tatarka-Ayakhta granites cannot be regarded as a full-scale orogenic process. Collisional events separating the Lower and Middle Baikalian are manifested as the erosional unconformity at the base of the Chingasan Group and the emplacement of the Glushikha granites (760–730 Ma). The Middle Baikalian age of the Chingasan deposits is constrained by the data from paleontology, historical geology, and geochronology. Furthermore, the presence of glacial deposits renders this straton as a global stratigraphic marker. Further expansion of transgression in the Upper Baikalian is linked to another important event, but additional paleontological and geochronological information is needed to date the Upper Baikalian (Chapa Group) more accurately. The Baikalian events synchronously manifested themselves in all structural-facies zones of the Yenisei Range and are coeval to structural complexes from adjacent areas of the Siberian Craton. The tripartite Baikalian, therefore, has a potential for being included into the General Scale of the upper Upper Riphean.

Abstract

The Borisikha ophiolite, composed of serpentinites and amphibolites, is an extension of the Isakovka ophiolite belt in the near-Yenisei part of the Yenisei Ridge. It is a slightly disturbed ∼3.5 km thick fragment of the ophiolite association; its crustal part is composed of metamorphosed wehrlite, troctolite, and gabbro cumulates. The cumulate composition and the geochemical features, which do not show any suprasubductional overprinting, indicate that the ophiolite is a normal oceanic lithosphere. Zircons extracted from pegmatoid amphibolite show sectorial magmatic zoning, low U contents, and magmatic Th/U values. The zircon age determined on a SHRIMP-II mass spectrometer is 682±13 Ma, which corresponds to the time of formation of oceanic crust. In the second half of the Late Riphean, the oceanic lithosphere that included the Borisikha ophiolite was subducted beneath the margin of the Siberian continent. At the same time, rifting, formation of half-grabens, and alkaline magmatism took place at the rear of the Yenisei Ridge. Similar events took place in southeastern East Sayan. Correlation between the coeval Late Baikalian structures along the southern and western margins of the Siberian Platform calls for special study.

Abstract

Four Precambrian metamorphic complexes in the vicinity of regional faults in the Transangarian region of the Yenisei Ridge were examined. Based on geothermobarometry and P-T path calculations, our geological and petrological studies showed that the Neoproterozoic medium-pressure metamorphism of the kyanite–sillimanite type overprinted regionally metamorphosed low-pressure andalusite-bearing rocks at about 850 Ma. A positive correlation between rock ages and P-T estimates for the kyanite-sillimanite metamorphism provide evidence of the regional structural and tectonic heterogeneity. The medium-pressure metamorphism was characterized by (1) the development of deformational structures and textures, and kyanite-bearing blastocataclasites (blastomylonites) with sillimanite, garnet, and staurolite after andalusite-bearing regional metamorphic rocks; (2) insignificant apparent thickness of the zone of medium-pressure zonal metamorphism (from 2.5 to 7 km), which was localized in the vicinity of the overthrusts; (3) a low metamorphic field gradient during metamorphism (from 1–7 to 12 °C/km); and (4) a gradual increase in lithostatic pressure towards the thrust faults. These specific features are typical of collisional metamorphism during overthrusting of continental blocks and are evidence for near-isothermal loading. This event was justified within the framework of the crustal tectonic thickening model via rapid overthrusting and subsequent rapid uplifting and erosion. The results obtained allowed us to consider medium-pressure kyanite-bearing metapelites as a product of collision metamorphism, formed either by unidirectional thrusting of rock blocks from Siberian craton onto the Yenisei Ridge in the zones of regional faults (Angara, Mayakon, and Chapa areas) or by opposite movements in the zone of splay faults of higher orders (Garevka area).
