Anoxia and fluctuating climate recorded from the Devonian–Carboniferous black shales, Tethys Himalaya, India: a multi-proxy approach

Due to inaccessibility and tough conditions (high-altitude low-oxygen region) very less information is available about the Indian Tethys Himalayan sequences, particularly geochemical data are scarce. An attempt is made in the present study to evaluate the sediment geochemistry and paleo-redox conditions of Devonian–Carboniferous black shales from the Spiti region, Tethys Himalaya, using multi proxy approach. Besides black shales, this paper also...
