摘要 铁厂钛铁砂矿床位于扬子准地台禄劝断凹处,成矿条件优越,勘查前景良好,但地质工作程度较低。对区域成矿背景、矿区地质条件、矿床地质特征进行了分析,并厘定了矿床找矿标志。研究表明:①矿区主要出露奥陶系、寒武系及第四系残、坡积层,第四系残、坡积层为矿区钛矿的主要赋矿层位,由黏质粉土及风化后的辉绿岩碎石土、砂土构成;②矿区构造继承了区域地质构造的特征,褶皱发育,其中养龙背斜的翼部与近核部的汇率岩体与成矿关系密切;③矿(化)体主要赋存于地形平缓的辉绿岩体分布区,矿体形态、产状严格受控于岩体,矿体规模与风化壳厚度成正相关;④矿体属典型的残、坡积风化壳型钛铁砂矿床,重砂矿物(钛砂矿、磁铁矿)的露头、漂砂、机械分散晕为寻找砂矿体的重要标志,平缓山坡、剥蚀台地及古侵蚀阶地等风化壳有利的保存部位,为寻找富厚矿体的有利部位。

Abstract: Tiechang Ti—Fe Placer Deposit is located in Luquan fault—concave of Yangtze Para—platform,which is characterized by superior metallogenic condition,favorable exploration and low exploration degree.Through detail analysis of the geological working results of area and deposit,the regional metallogenic geological background,geological characteristics of the mining area and the deposit are summarized,besides that,the prospecting criteria is also discussed.The research results show that:①Ordovician,Cambrian and residual/slope of sediments of Quaternary are occurred in the mining area,the residual and slope of sediments of Quaternary is the mainly ore—hosting strata,which lithology are mainly for clayey silt,gravel soil and sand soil of diabase;②affected by the regional tectonics activities,the mining area is characterized by fault development,and the alar part and the center part have closely related to the mineralization;③the orebodies (mineralization) are mainly occurred in the flat area with diabase rock mass,which is strictly controlled by rockmass,there is a positive correlation between the sale of orebodies and the thickness of weathered crust;④Tiechang Ti—Fe Placer Deposit belongs to the residual/slope sediments weathering—crust type deposit,the outcrop of placer mineral (titanium placer,magnetite),bleaching—sand and the mechanical halo dispersion can be regarded as favorable prospecting criterias for finding the placer,and gently hillside,erosive platform and erosive terrace are the favorable destribution positions for rich deposit.
