摘要
雅安烟溪沟钛矿位于上扬子陆块西南缘,矿体产于二叠系上统宣威组底部的杂色—红色泥岩中,以层状沿地表呈面型分布。本文通过野外调查,在矿石矿物组成特征与常量元素组成特征研究的基础上,对矿体的赋存特征、物质来源、成因类型与机制进行了总结,得出以下认识,钛矿石含钛矿物主要为锐钛矿;物质来源主要为二叠系上统的高Ti玄武岩;成因类型为一种新型沉积型钛矿。
Yanxigou titanium deposit is located in west-south margin of the upper Yangtze plate.The layered orebodies occur in the variegated-red mudstone of Permian Xuanwei Formation and are distributed along the surface.Based on the field investigations,study on mineral components and major elements,the characteristics of ore body occurrence,the ore-forming materials sources,the genetic type and mechanism of ore deposit have been summarized.And finally come to the following conclusions,the titanium ore consists mainly of anatase,and the ore-forming materials sources is the Permian high Ti basalts,the genetic type belongs to a new type of sedimentary deposit.
