文摘The Maxianshan area is rich in fluorite resources, the fluoritation was apparently controlled by the stratum, structure and the petrography and possesses the characteristics of the strata-bound deposit. The controlling stratum is AnZmx2-3 and Z1xn4. The country rocks are mainly migmatite, and secondly, the migmatic granite,
