摘要
本文通过对云南西部兰坪铅锌矿床、金满铜矿床、勐野井钾盐矿床和腾冲松木箐金矿床的地质地球化学研究,认为它们是在陆相条件下热水沉积形成的。根据矿床的产出特征,把陆相热水沉积的矿床划分为3种类型:泉华沉积型;盆地沉积型;脉状沉积型。本文还对热水沉积矿床与现代海底热水(喷流)矿床进行了对和提出了陆相热水沉积的成矿模式,最后对我国陆相热水沉积矿床的找矿方向提出了粗浅的建议。
Through studies on geology and geochemistry of Lanping lead-zinc deposit. Jinman copper deposit, Mengyejing potash deposit and Songmuqing gold deposit in Tengchong in western Yunnan. it is considered that they were formed due to hydrothermal sedimentation under the continental condition. According to their occurrence characteristics,the continental hydrothermal sedimentary deposits can be divided into three types:sinterite type:basin sedimentary type and vein-like sedimentary type. In this paper comparison is also made between hydrothermal sedimentary deposit and modern submarine hydrothermal (exhalative)deposit and the metallogenetic model for continental hydrothermal sedimentation is proposed. Finally,a superficial suggestion is advanced to the prospecting direction for continental hydrothermal sedimentary deposit in China.
