Paleoenvironment of Carboniferous Shales in Wuwei Basin

摘要

Shales are enriched with diverse suites of trace elements that reflect their depositional environment. The purpose of this paper is to restitute the paleoenvironment of Carboniferous shales in Wuwei basin. In this study, we used and analyzed comprehensively trace elements (B, Sr, Ba, Ga, V, Ni, Co, U, Th) data of shales. We resulted that shales for Carboniferous from the southern margin of the Wuwei basin were deposited in the hot and salty marine-continental transition environment.
