摘要
在当前全球资源危机、矿产品价格大幅度上扬、国内矿产资源紧缺的不利形势下,为了加快铁矿资源的勘查和开发.在对朱溪河钛磁铁矿含矿碱辉辉绿岩地质特征、矿体特征以及钛的赋存状态进行重新分析、认识的基础上,详细介绍了陕西省紫阳县钛磁铁矿的矿床地质特征,探讨了矿床的成因机制,并且指出该矿床具有矿体规模大、形态简单的特点.矿床属岩浆早期分异型钛磁铁矿床,其成矿时代为晚奥陶纪-早志留纪.其深部有很好的找矿前景.该矿床的成因模式对在南秦岭辉绿岩带中寻找大型钛矿床具有指导意义.
In view of the current global resource crisis,sharply rising commodity prices,and serious shortage of domestic mineral resources,it is necessary to speed up the exploration and development of iron ore resources.This paper introduces the deposit geological characteristics of titanomagnetite in Ziyang County of Shaanxi Province in detail on the basis of reanalyzing and understanding the Zhuxihe titanium magnetite ore in terms of geological characteristics of containing alkali-hui diabase,ore body characteristics and existing states of titanium.It also discusses the cause of deposit＇s formation,and points out that the ore deposit is characterized by large ore body in scale and simple form.The ore deposit belongs to the early magmatic differentiation-type titanium magnetite ore,and is formed in the Late Ordovician---Early Silurian.The formation model of the deposit has great guiding significance in prospecting the large-scale titanium deposit in the South Qinling diabase belt.
