摘　　要：百地金矿发现至今已20多年,断续开展了勘查工作,但没有较大突破,本文通过对近期的勘查及研究成果的综合分析,总结描述了矿区基本地质、金矿化特征及地球化学特征。通过构造演化分析,提出区内地质构造主要由两次主要的构造活动形成,即北东向和东西向的挤压;主要的容矿构造为近东西向和北西向,成矿受构造活动的影响,主要矿体向北西或南西侧伏,提出今后的找矿方向,对该区及相邻地区找矿及勘查工作具有指导意义。This paper reports the metallogenic forecasting research on Baidi gold deposit in Ceheng County of Guizhou Province,China.Baidi gold deposit has been discovered for more than 20 years.The geology exploration has been conducted many times but no significant breakthrough was made.This paper summarized the basic geology and gold mineralization features as well as geochemical features based on the synthetic study on existing historical data and achievement.Through the analysis of structure evolution of the structures within the deposit,this paper indicates that the structures within the deposit are mainly developed due to two stage’s structure activities and compression of NE and EW direction.Main mineralization containing structures are approximately EW trending and NW trending structures and the metallogenic structure.The main orebody is plunging to NW or SW.The prospecting direction is therefore proposed.This should be with some guidance significance for its prospecting and the prospecting activities at nearby area.
