【摘要】 金在成岩阶段表现为亲铁性,在热液成矿阶段表现为亲硫性,在表生条件下金具有被碳、泥质吸附的地球化学属性,因而在地壳演化的不同阶段也显示出不同的成矿特点.金矿化集中区的提出为金的区域成矿研究提供了新的思维,微细浸染型(卡林型)金矿床和浅成低温热液成矿作用的确认促使金矿床勘查得到了空前发展.重要金矿化集中区成矿环境的厘定、金矿床成矿流体演化和金元素的巨量聚集与超大型矿床的形成是当今金矿床研究的前沿.更多还原

【Abstract】 Gold mineralization displays various characteristics in different stages of crustal evolution. In diagenetic stage, gold expresses siderophilicity. In the stage of hydrothermal metallogenesis, it shows thiophilicity. While in the epidiagenetic condition, the element is geochemically characterized by the adsorbality by carbon and argillaceous matters. The concept of " concentrated region of gold mineralization" provided a new idea for the study of regional mineralization of gold. The confirmation of fine impregnated mineralization(Carlin type) and epithermal gold deposit has greatly improved the exploration for gold deposits. The frontier fields for the present study focus on the background of the concentration regions of gold mineralization, the evolvement of ore forming fluid and the genesis of superlarge gold deposits.<P>更多还原
