摘要
湘中龙山金锑矿处于区域性构造交汇部位.矿床主要受构造破碎带控制,扭张性破碎带比扭压性破碎带矿化更富集,金的初始来源为深源,经沉积成岩过程初步富集形成矿源层,印支期及燕山期构造活动及岩浆侵入加热了循环大气降水,混合岩浆热液溶解了矿源岩中的金、锑成矿元素,并随流体迁移至成矿有利部位形成矿床.成矿流体主要为大气降水,混合岩浆热液.矿床成因类型属于中低温热液蚀变破碎带型金矿.
Longshan Au-Sb deposit is located in intersection parts between regional structures. The deposit is subject to crush belts, and the tension-shearfault mineralizing enrichment more than compresso-shearfault. The initial source of the ore-forming materials comes from deep focus. And preliminary enriched to form the source beds through the sedimentation and diagnosis. The circulating precipitate water, which is heated by tectonic and magrnaticintrusion in Indosinian and Yanshanian, mixed with magmatic water dissolved Au-Sb elements. The ore-forming elements formed a deposit in a favorable setting, transported by fluid. Metallogenic fluid stemmed from precipitate water and mixed with magrnatic water. The genetic type of ore deposit belongs to medium-low temperature hydrothermal altered elastic zone type deposit.
