摘要
This paper studies the geologic background of mineralization,geological feature of orebody, ore characters, characters of petrochemistry composition, REE characters of rocks and ores, and Sm-Nd isotope of Bamianshan fluorite deposit. It shows that Bamianshan fluorite deposit is an unusual large fluorite deposit which was formed mostly by sedimentation and later hydrothermal reformation. Based on the data and combined with characters of ore-hosted rocks and orebody, it is predicted that the sedimentary rocks of Cambrain System as source bed, which supplied necessary materials for Bamianshan fluorite deposit. Magmatism in later stage altered some orebodies in different extent and formed partial deep lean vein ore bodies in structure belt.
