贵州普安泥堡金矿床构造控矿特征及找矿方向

摘要

Nibao Gold Deposit in Pu ’ an,Guizhou Province ,belongs to a typical carlin type gold deposit and its tectonics is a decisive factor to control the formation of the deposit .The latest data from deep exploration indicate that the thrust nappe structure ,detachment structure and ancient landslide mass are the 3 major structures that control the orebody formation and distribution and that the main orebodies are directly hosted in the footwall thrust fracture broken belt.After the introduction of deposit features ,the paper focuses on discussing the ore-controlling structural types and its control effects ,and finds out the metallogenic potentials and favorable prospecting sections ,in hope to provide refer-ences and revelation for the deep exploration work of carlin type gold deposits in southwestern Guizhou .%泥堡金矿床属于典型的卡林型金矿床，构造是控制该矿床形成的一个决定性因素。矿区深部勘探最新资料表明，逆冲推覆构造、滑脱构造和古滑坡体是控制矿体形成与分布的3种主要构造类型，主矿体直接赋存于底板逆冲断层破碎带中。在阐述矿床特征的基础上，着重讨论控矿构造类型及其控矿作用，并指出成矿潜力及找矿有利区段，以期为贵州西南地区卡林型金矿床深部找矿勘探工作提供有益参考或方向启示。
