摘要
八庙青山作为我国金红石成因及工业类型代表的重要矿床，是高钛岩系在一定变质条件下形成的。通过采用矿物温度、压力计等方法的研究，估算出本区变质条件与成矿的关系：利于成矿的最佳温度为４９０．４３℃，压力为３．８２×１０８Ｐａ，环境为还原环境。
Calcite deposits in the northern part of Dingyuan county, Anhui have a close link with development of geological stuctures, particlarly joints in the study area. Three sets of major joints, though each subjected to a principal stress fields at a given phase, all experienced a succession of shear following open late rework. The joint sets of the ore controlling zone as a whole developed from opening to closing, and some, following joints caused by the superimposition of the second phase stress field associated with the sinistral striking of Tancheng lujiang fault, provided favorable rooms for crystalline materials to fill.
