五星铂钯铜镍矿床位于敦密断裂南东侧的兴凯地体内，矿床内不仅含有铜镍钴矿体，同时含有贵金属铂钯矿体。通过对铂钯元素在岩石、矿石及矿体中的物相分配、赋存规律的研究，发现矿体中贵金属钯铂主要以2种形式赋存，即矿物相及类质同像，且类质同像又分为硫化物中的类质同像、造岩矿物及氧化物中的类质同像。研究表明，钯铂主要以矿物相存在，硫化物中的类质同像次之，造岩矿物及氧化物中类质同像的赋存形式较少。
五星鉑鈀銅鎳礦床位于敦密斷裂南東側的興凱地體內，礦床內不僅含有銅鎳鈷礦體，同時含有貴金屬鉑鈀礦體。通過對鉑鈀元素在巖石、礦石及礦體中的物相分配、賦存規律的研究，髮現礦體中貴金屬鈀鉑主要以2種形式賦存，即礦物相及類質同像，且類質同像又分為硫化物中的類質同像、造巖礦物及氧化物中的類質同像。研究錶明，鈀鉑主要以礦物相存在，硫化物中的類質同像次之，造巖礦物及氧化物中類質同像的賦存形式較少。

Wuxing Pt-Pd-Cu-Ni Deposit is located in Xingkai Terrane which lies in the southeastern part of the Dunhua-Mishan Fault .The deposit contains not only Cu-Ni-Co ore bodies but also Pt-Pd.This paper mainly discussed the physical distribution and occurrence regularities of Pt-Pd elements in the rocks ,ores and ore bodies .The precious metal elements Pt-Pd have two manners of existence i .e.mineral facies and isomorphism that further divides to isomor-phism in metal sulfide , and isomorphism in rock-forming minerals and oxides .And studies show that the Pt-Pd ele-ments mainly exist in the form of mineral facies ,secondarily isomorphism in metal sulfide ,and least likely in the form of isomorphism in rock-forming minerals and oxides .
