| 摘 要： | 以阳山金矿为核心的甘肃阳山整装勘查区是中国107片整装勘查区之一。勘查区位于中央复合造山带中段西秦岭南缘,该区构造-岩浆演化复杂,成矿地质条件优越。区内以阳山、新关、关牛湾、塘坝等为主的金矿床,经过近20年的地质勘查和科研工作,取得了重要进展,目前勘查区正处于找矿勘查实现更大突破的关键时期。文章在系统梳理前期勘查和研究成果基础上,并经野外详细调查和分析,提出制约整装勘查区找矿突破的关键科学问题:基过于勘查区所处的大地构造环境和复杂造山过程,需从全新角度认识勘查区成矿地质环境和成矿作用的演化;基于野外勘查新发现的地质事实,进一步查明区内多期构造-岩浆活动与成矿的时空、成因联系和耦合关系,厘定多期成矿作用叠加改造及其对成矿产物的影响;从整装勘查区乃至区域成矿带巨量金聚集的角度,深化巨量成矿物质来源研究;全面分析阳山整装勘查区内典型金矿床特点,并通过与国内外典型矿床的对比研究,确立区内金矿床的成因类型和勘查类型;以区内复杂构造演化为脉络及其对成矿的控制研究,提炼主要控矿因素和找矿勘查标志;面向找矿突破的总体目标,全面总结勘查区、矿田和矿床等不同层次的成矿规律,系统全面评价勘查区资源潜力和找矿勘查方向。

| Abstract: | Yangshan gold integrated exploration area,located in the south border of West Qinlin region, middle part of the center compound orogenic belt(West Kunlun-Qinlin-Dabie) in China, is the one of 107 the integrated exploration areas. Because of the complicated tectonic-magma evolution and superior metallogenic condition, a lot of Au (Sb) deposits, such as Guanniuwan, Xinguan, Tangba, Jinkenzi, especially Yangshan super-large gold deposit have been found in this area. After recent two decades prospecting and studies, the prospecting area is at a key period for achieving breakthrough in resource. Based on the former prospecting and research data, by detail field in vestigation, some key science problems of mineralization and prospecting in Yangshan prospecting area has put forward as follow:the region tectonic settings and mineralization events should be recognized in a completely new metallogenic theories; the relationships between multiphase tectonic-magmatic activities and mineralization, include spatio-temporal, genetic, superimposition and reform of multi-stage mineralization to ore bodies must be studied in a deepgoing way according to the new facts observed in the mines; the accumulation mechanism and origin of enormous amount Au in this prospecting area and the regional mineralization belt are still quite vague; the genetic and exploration types of the main deposits have remained debatable, and the regional or ore district metallization regularities of typical and important deposits must be further discussed and summarized; in order to realized the overall goal of prospecting breakthrough, the ore finding signs and directions, the main ore controlling factors and the prospecting potential need to be solved imminently. |
