Fauna from the iron ore pit of the Sarbaiskoye deposit

Abstract

The deposit lies among dislocated and metamorphosed sedimentary-volcanogenic rocks of Paleozoic age (Valerian Formation), which have a monoclinal bedding with a westward dip at an angle of 40-45°. The deposit consists of three stratum-shaped ore bodies occurring in accordance with volcanogenic-sedimentary rocks: Western, Eastern and Southeastern. The age of the ore-bearing strata of the Sarbaiskoye deposit has so far been determined by foraminifera from the core of the well located near the Western ore body (middle-upper Visenian to Lower Namur). Our faunal discovery belongs to the tuffite horizon composing the hanging wall of the Eastern ore body ...
