| 摘 要： | 西峡金红石矿床位于秦岭造山带东段南缘，是一个大型角闪质片岩型金红石矿床。矿体赋存于古生界信阳群龟山组第三段，含矿岩石为含金红石角闪质片岩。本文阐述了矿区地质、矿体和矿石特征、钛的赋存状态及分布规律、热液蚀变等，认为该矿床属变质热液改热门造的火山─沉积变质型金红石矿床。

| Abstract: | The Xixia rutile deposit sits in southern border of eastern block of the Qinling orogenic belt. It is a large deposit of hornblende schist type. Orethey occurs in the third member of Guishan Pormation,Paleozoic Xinyang Group.The ore-bearing rock is the rutile hornblende schist,Geo-logic conditions of the Xixia rutile ore district,features of orebody, ore,occurrence state,distri-bution of Titanium and hydrothermal alteration are expounded in this paper.It is believed that metallogenesis is metamorphosed volcano-sedimentary rutile ore deposit,subjected to regional metamorphic hydrothermal reconstruction. |
