南岭西段锡矿类型与找矿前景

通过对南岭西段锡矿成矿特征的分析总结，依据成矿构造类型、赋矿围岩性质及矿体形态差异等特征，将南岭西段原生锡矿分为六种主要类型；并结合其成矿控制条件及矿化富集规律的研究，认为南岭西段锡矿找矿前景可观，提出岩体型、矽卡岩型和破碎带蚀变岩型是南岭西段锡矿的主攻类型，主攻地区为姑婆山岩体西南接触带、都庞岭岩体北接触带和花山岩体中的三叉地区。

TIN DEPOSIT TYPE AND ITS EXPLORATION PROSPECT IN WESTERN NANLING

The primary tin deposit in western Nanling is divided into six main types on the base of the analysis of metallogenic characteristics including metallogenic structure type, host rock feature and the difference of orebody shape. It is believed that there is a great potential for tin deposit exploration in western Nanling according to the study about ore controlling conditions and mineralization accumulation regularities. The target types are magmatite, skarn and breccia-zone-altered-rock type tin deposit in western Nanling.The target areas are southwestern contact zone with the Guposhan magmatite, northern contact with the Doupanling magmatite and the trifurcate area in the Huashan magmatite.
