New Type of Fluidizate-Explosive Rock in Sedimentary Strata (Torgashino Limestone Deposit, Eastern Sayan Mountains, Russia)

摘要

The paper provides the results of comprehensive studies of bodies composed of different fluidolite types (psephitic, argillizite) and hydrothermalites found in the carbonate stratum of the Torgashino suite (Eastern Sayan Mountains, Russia). These rocks are the result of post-sedimentation processes imposed on limestones. Argillizites in the carbonate stratum are referred to a new type of fluidizate-explosive rock. Their low-temperature hydrothermal origin and association with the Later Ordovician tectono-magmatic activation of the area have been identified.
