摘　　要：二郎坪群位处扬子板块和华北板块的拼合带——秦岭造山带的东段,夹持于NW向瓦穴子-乔端、朱阳关-夏馆两个区域性深大断裂之间,由于特殊的大地构造位置和成岩成矿环境,受到国内外众多地质学家的关注。本文以笔者近期开展的二郎坪群1:5万找矿填图和成矿规律研究的最新资料为依据,结合前人大量地质和科研工作的多项成果资料,着重论述二郎坪群的地质特征及成矿规律,为本区的广深找矿工作提供科学依据和理论支撑。Erlangping Group is located between northwest-trending Waxuezi-Qiaoduan and Zhuyangguan-Xiaguan regional deep fault of eastern Qinling orogenic belt which is formed by collision of Yangtze plate and North China plate.The special tectonic environment and great metallogenic potential of Erlangping Group makes it the famous research focus in the geologist＇s world.Combined with many previous geological works and research literature,the geological characteristics and metallogenic regulations of Erlangping Group are illustrated,which can provide scientific basis and theoretical support for future ore prospecting in this area.
