| Garnets from the Lower Triassic clastic reservoirs of the northern part of Kolva megaswell (Timan-Pechora petroleum province) | |
| Recent years, when studying terrigenous reservoirs of oil and gas regions, more and more attention has been paid to the study of accessory minerals of clastic rocks, in order to clarify the composition of provenances and the conditions of formation of terrigenous rocks, as well as the correlation of "barren" beds. The article presents the results of lithological and mineralogical study of the Lower Triassic sandstones of the north of the Kolva megaswell of the Timan-Pechora petroleum province. It is shown that almandine predominates among the minerals of the garnet group. It is suggested that one of the sources of clastic material was metamorphic rocks that were widespread in the northern part of the Lyapin anticlinorium. In the Early Triassic time, the reorganization of the structural plan continued, associated with the formation of uplifts in the Paleo-Urals region, which led to an increased removal of polymictic material to remote areas of the platform. It is assumed that garnet group minerals can be used as indicator minerals in the search for lithological and lithological-stratigraphic hydrocarbon traps. The presence of these minerals in the clastic part of sandstones is determined not only by the sources of material removal, but also by the nature of the change in terrigenous components depending on the conditions of sedimentation; it depends on the size of the clastic material and on the physicochemical properties of the minerals. Keywords: garnet group minerals, sedimentation condition, sources of material removal, Lower Triassic clastic reservoir, Kolva megaswell, Timan-Pechora petroleum province. |
