摘　　要：贵港龙山金矿田受近SN向的断裂构造控制,成矿物质来源于深部,属于中低温构造蚀变热液型金矿床。以平天山岩体为中心,源于深部的含矿热液,在燕山晚期岩浆岩侵入活动过程中,伴随着的气化—热液成矿作用,构成一套成矿发展阶段的成矿系列,在不同的构造、岩性部位,形成的一套不同类型金矿床组合,具有多阶段多期次成矿富集的特征。As a medium-low temperature tectonic altered hydrothermal Au deposit,Longshan Au ore field in Guigang is controlled by SN strike faulted structure and its ore-forming matters are derived from deep strata. Centered on Pingtianshan rock body and generated from deep mineral-bearing hydrothermal solution,metal-logenic series of a set of ore-forming development stages is formed under the condition of pneumato-hydro-thermal mineralization.At different structures and lithological parts,a set of different types of Au deposit compositions is formed and is characterized by multi-phase multi-period mineralization and concentration.
