Abstract:

Copper—nickel deposit of Hotlgqihng is located in Huifahe fault which is contacting zone of North China platform and Jihei geosyncline，it is a large scale deposit．In mineral area，the stratum which is crop out is Hulan group’s metamorphic rocks. Huifahe fault is characteristic of cutting deeply and frequent inheriting activity，its stretch is norrtheast．The northwest faults are derived from Huifahe fault，they are important the structure of controlling-rock and controlling-ore， controlled the distribution of mafic, ultramafic rocks and ore-body of copper-nickel sulfide．The rock-body which have the relation of mtallogenic of copper—nickel ore have the characteristic of compound rock-body．They belong to mafic, ultramafic rocks which type are gabbro，pyroxenite and peridotite．The ore-bodys of copper-nickel are seated in mafic，ultramafic rocks，the shape are similar slaty， nervation， lentiform and cystiform． The characteristic of microelement and REE geochemical have proved the ore-bodys come from mantle liquation．Mine and mafic，ultrafic rocks have consanguinity．The authors ascertained the genesis of ore deposits are deep magmaticand differentiation．
