摘要
The research shows that the perlite, zeolite, bentonite, pyrophyllite and kaolinite deposits occur mainly in intermediate-acid volcanic rocks of the Manketouebo Formation, Manitu Formation, Baiyingaolao Formation and Yixian Formation in Chifeng area as the perlite-zeolite-bentonite and the pyrophyllite-kaolinite deposit series. Research reveals that the deposits are controlled by NNE regional fault and Mesozoic volcanic formation temporally and spatially. Genetic type and association of the deposits are controlled by the ore-forming processes, geological characteristics by the host rocks, rework by the micro-environments. In this paper, three perlite-zeolite-bentonite ore belts and the Chaganmulun-Halahada-Hansumusumu pyrophyllite-kaolinite ore belt are delineated and the genetic models of perlite-zeolite-bentonite and pyrophyllite-kaolinite deposit series are established in Chifeng area.
