Geochemical characteristics of the Permian marine mudstone and constraints on its provenance and paleoenvironment in the Fenghai area, Fujian Province, southeastern China

Abstract Permian marine strata have gradually become a research focus in the world. The marine strata of the Late Permian Dalong Formation (P3 d) in the Fenghai area, Fujian Province, have become more and more important as their geochemical characteristics record important geological information and...
