湖南柴茅岭锡矿地质特征及找矿预测

骑田岭地区位于炎陵-郴州-蓝山北东向基底构造岩浆岩带中部,是南岭中段多金属成矿带的重要组成部分,具有断裂构造异常发育,存在多期次岩浆活动、多类型矿床和矿种组合的特点。柴茅岭矿区位于骑田岭岩体西南。近年来在骑田岭地区锡矿勘查取得重大突破。文章在介绍矿区内成矿地质背景的基础上,对其地质特征及控矿因素进行了分析,并进行了科学的预测定位,为下一步找矿提供新的认识和思路。

Geological characteristics and prospecting forecast analysis on Chaimaoling tin deposit in the southern Hunan Province

Qitianling area which located at the middle part of the Yanling-Chenzhou-Lanshan NE-trending tectonomagmatic belt of basement is an important part of polymetallic metallogenic belt in the middle of Nanling region,This area has extensive fault structure,sufured multiperiod magmatic activity such as the intrusion of Qitianling granite,and produced many types of ore deposits with multy minera.The Chaimaoling orefield is located in the southwest of Qitianling granite.The breakthrough in tin exploration in the Qitianling area,Hunan Province,is a major achievement scored in the large-scale land and resources survey in recent years.This paper introduces the geological setting of the orefield,summarizes the geological characteristics of the deposits,analyzes their ore-controlling factors,and makes scientific prediction and localization.This paper provides new ideas and thoughts for next prospecting work.
