摘要
半边山含金斑岩，赋存于桃江花岗闪长岩体外接触带冷家溪群中，已发现１２条岩脉，呈北北东向带状分布。金以细粒自然金为主。金矿化主要富集在石英斑岩内的石英脉、蚀变带及其接触破碎带中。它的发现，具有现实意义和找矿意义。
Banbianshan gold─bearing porphyry, occurred in Lengjiaxi Group in the external contact zone of Taojiang granodioritic intrusion。12 veins have been located along a NNE trending zone. Gole exists mainly in the form of fine─grained natural gold. Gold mineralization concentrated mainly in quaraz veins,alteration zone and its contacting fracture zones within the quartz porphyry.Its discovery is of significance not only in economic reality.but also in searching for gold.
