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.
