Preservative Features of the Fossils in Bauxite Deposit of WZD Area, Northern Guizhou, China

Abstract

It is hardly to discovery fossil from the bauxite in Wuchuan-Zheng, an-Daozhen (WZD) area, northern Guizhou, China. But the new study suggests, containing a small amount of plant debris from massive bauxite in the lower part of the ledge. Preservative features of fossils in WZD bauxite indicates: metallogenetic materials experienced a transport process; sedimentary environment is reduced; fossils only preserved in the massive bauxite, that fossils in other types of ores were destroyed in the late oxidation modification. Metallogenic environment of bauxite has experienced two kinds of state-reduction and oxidation. The lack of animal fossils; bauxite, reveal that the metallogenic environment is acidic, resulting in animal fossils are dissolved and hard to save.
