摘要：

河南嵩县下蒿坪金矿区构造、岩浆活动强烈，具有良好的成矿地质条件。矿床受地层、断裂、火山角砾岩和爆破角砾岩联合控制，以构造控矿为主，属破碎带蚀变岩型金矿床。矿石结构构造简单，以混合矿为主，其次为氧化矿和原生矿。金以不规则粒状自然金和银金矿形式存在，以裂隙金、晶隙金和包体金产于黄铁矿、石英等载金矿物的内部及其裂（间）隙中。金粒度以细粒和中粗粒为主，微粒金较少，易于选矿。

Abstract:

The structure and magma activities of Xiahaoping gold deposit are stong,and it has a good metallogenetic geological condition.Ore deposit is controlled by stratum,fault,volcanic breccia and explosion breccia.The tectonic is the main controlling factors.Xiahaoping gold deposit belongs to a typical structural alteration rock type deposit.The texture and structure of ore are simple.The mixed ore is main ore type,oxidation and primary ore followed.The gold behaves irregular granular native gold and electrum,mainly occurred in gold-carrying minerals（such as pyrite,quartz） in the from of fissure gold,intercrystalline gold or inclusion gold.The size of gold is mainly coarse-medium gold and mustard gold,and the gold-cluster is minor.It is esay ore-dressing.
