| 中文摘要: |
| 金川铜硫化物矿床铂族元素球粒陨石标准化型式属于Ｐｔ－Ｐｄ配分类型，Ｐｔ、ｐｄ〉Ｏｓ、Ｉｒ、Ｒｕ、Ｒｈ，存在３种不同形式的图形；ＰＧＥ（铂族元素）在熔离和深熔－－贯入型岩矿体中，ＰＧＥ含量从非含矿岩石→ＳＮ－Ｂ→ＳＮ－Ａ２→ＳＮ－Ａ１依次增加，显示与金属硫化物含量具有正消长关系；矿石中８０％以上的铂和７０Ｔ以上的钯呈矿物相存在；ＰＧＥ富集体主要分布在富矿体膨大处的中、下部。 |
| 英文摘要: |
| The Jinchuan Cu-Ni sulphide deposit is hosted in ultrabasic intrusions. The platinum group elements (PGE) is Pt-Pd partition type in the chondrite normalization pattern with higher contents of Pt and Pd than Os, Ir, Ru and Rh, and have three different figures. In the liquation type and deep liquation-abyssal injection type orebodies, the PGE contents are gradually increased from barren rocks through SN-B, SN-A 2 to SN-A 1, and show a positive correlation with the contents of sulphides. More than 80% of Pt and 78% of Pd occur in ores as mineral phases. PGE are enriched in the copper and nickel bonanzas, especially in the middle and lower part of them. |
