根据贵州省西南部泥堡金矿床深部勘探成果，开展其矿床的矿体类型及其形成机理的综合研究，取得新认识如下：（1）矿区的主矿体不是层控型，而是断控型。断控型矿体的单个矿体规模大，厚度、品位较稳定，而层控型金矿的单个矿体规模小，厚度及矿石品位变化大；（2）虽然矿床的形成受到多种因素控制，但构造、地层及其有利岩性是关键的控制因素，尤其是断裂构造因素。F1逆冲断层既是导矿构造又是容矿构造，本矿床最大的金矿体就赋存于F1断裂破碎带中的减压扩容带，即断层破碎带变宽及断层面变缓部位。这两点新认识对区域找矿具有一定指导意义。

AccordingtothedeepexplorationresultsofNibaogolddepositinsouthwestGuizhou,thecom-prehensible study of orebody type and its formation mechanism are finished and some new cognizance are a-chieved:(1)The major orebody is fault-controlled but not stratum controlled,the fault-controlled single ore-body is big,the thickness and the grade are stable,but the single orebody of strata bound gold deposit is small,the thickness and the grade are not stable.(2)Although the deposit formation is controlled by different factors,structure,layer and it advantageous lithology are the key points,especially the rift structure.The trust fault F1 is not only ore-transmission structure but also ore-bearing structure,the biggest orebody of this de-posit occurred in the decompression and expansion zone of trust fault F1 where the trust fault is wider and the fault is slower.These 2 cognizance has some guiding significance for regional exploration.
