湘南锡矿找矿方向探讨

湘南地区蕴藏着丰富的锡矿资源,锡及锡多金属矿矿床(点)分布广泛,类型复杂,它们的形成除与花岗质侵入岩体直接相关外,同时还受到区域地层和地质构造等因素的共同制约。通过对锡矿的地质背景、分布特征、矿床特征与矿化规律、矿床成因及找矿信息和标志的研究,把湘南地区锡矿的找矿归纳为:"划带、圈区、寻体、定位"的找矿模式,不仅从宏观上提出了或解决了锡矿找矿方向的问题,而且近几年来的地质找矿工作得到了实践应用,并取得了丰硕的找矿成果。

Direction for looking for tin deposits in southern Hunan

Abundant tin resources are contained in the southern Hunan region. Tin and tin-polymetallic deposits (occurrences) are widespread in the region and their types are complex. Their formation is not only directly related to granitic intrusions but also controlled by factors such as regional strata and geological structure. According to the geological setting, distribution characteristics, deposit features and mineralization characteristics, deposit genesis and ore search information and indicators, the ore search model for tin deposits in the southern Hunan region may be summarized as "delineation of ore belts and ore districts, search for mineralized intrusions and determination of ore deposit locations". This model not only macroscopically presents or solves the problem of the direction for looking for tin deposits but also has been applied in ore prospecting in recent years, and fruitful results have been achieved in ore finding.
