摘    要:印支期暗色、致密块状辉绿岩中含较高的含铁矿物,地磁异常较高,为矿源层。辉绿岩与灰岩接触形成矽卡岩带为有利的含矿带。矿体沿大断裂或次级断层形成的通道侵入穹窿状构造中,于二叠系砂岩、板岩隔层的下部形成工业钛铁矿体。

关 键 词:钛铁矿  辉绿岩  矽卡岩带  穹窿构造  洞哈富宁云南

Abstract:The content of Fe - bearing mineral is very high in Indosinian melanocratic dense massive diabase with high geomagnetic anomaly, which is the ore source bed. The skarn zone on contact of diabase with limestone is the advantageous ore -bearing area. The ore -bearing rock body intrudes the blind brachy - anticline or the arch formed by brachy - synclinal basin along the channel formed by fault or secondary fissure, which forms the industrial ilmenite ore body in the lower part of blockage bed of Permian sandstone, slate.
Keywords:Ilmenite  Diabase  Skarn Zone  Dongh'a  Funing  Yunnan
