Abstract
Gold deposit geological feature and ore deposit origin of Machanggou of Haiyuan County in Ningxia are studied.The results shows,the ocurrence of the gold ore is on the West Huashan arc nappe structure,the mineralization stratum is the Haiyuan group stratum of proterozoic section of Jixian;the gold ore body and mineralized body mainly spread on northwest ore belt,its length reaches 3.5 km,and its shape likes broom which is dispersive in east and constrictive in west.On the mineral zone,14 gold ore bodies and mineralized body which have been discovered,main composition is bright porphyry,second is quartz vein,and altered mineral is the less.Genesis of deposit is closely related to regional metamorphism,regional structure and magma activity,its type is a metamorphic deposit-hydrothermal gold deposit.
