铂族元素矿床研究现状及对山东找铂矿的建议

Present Condition of Study on Platinum - group Elements Deposits and Suggestion for Prospecting It in Shandong Province

摘要:

山东省还没有发现过独立的铂族元素矿床,但在济南历城铜镍矿床中存在可回收的伴生铂族元素。在众多的中生代金矿床中铂族元素常常出现,虽然还没有经济意义,但可作为寻找新的铂族元素矿床的线索。根据近年来国内外铂族元素地质找矿与成矿理论研究的新进展,在山东寻找铂族元素矿床是值得注意的。山东可能存在多个时代(太古宙、元古宙和中生代)的成矿作用,矿床类型也可能是多种多样的,如与基性—超基性岩有关的济南历城式铜硫镍化物型矿床、与金伯利岩筒有关的铂族元素矿床和热液成因多元素组合的铂族元素矿床等。

Abstract:

There is no independent platinum deposit found in Shandong province, but recoverable associated platinum elements maybe occcur in Cu - Ni deposit in Licheng, Jinan city. Platinum elements always occur in Mesozoic gold deposit which can provide clue for propecting new platinum - element deposit. According to new developments of platinum -probing and ore - forming theory in recent few years, Shandong should be paid more attention in propecting platinum - element deposit. Multi - periods ore - forming function occurred in Shandong with many kinds of deposit types, such as Cu - S - Ni type platinum element deposit in Licheng which has close relation with basic - super - basic rocks, and platinum element deposit which has close relation with kimberlite pipe and geothermal multi - elements combination.
