| 摘 要： | 根据埃达克质岩的特征、时空分布及有关矿产的产出情况，将中国与埃达克质岩有关的矿床分为产于造山带和产于陆块内两大类，若干成矿带(区)和次一级的成矿亚带。与前者相关的有古亚洲洋、秦祁昆洋、环太平洋和新特提斯成矿带；与后者相关的有中国东部、青藏高原和藏东南一川西南一滇西北成矿(区)带。埃达克岩与成矿作用的密切关系开辟了一条围绕埃达克岩来找矿的新思路。根据中国的现状和未来发展的需求，从立足于找大矿和世界级大矿出发，认为我国寻找Cu，Au，Mo和Ag等的找矿方向应当从战略目标、近期目标和远期目标3个不同层次来考虑，希望加强在古亚洲洋造山带和冈底斯造山带的找矿工作。在评述了早期和现行的找矿方法后，初步拟定了在埃达克岩出露地区的找矿思路，建议将埃达克岩作为找矿勘查的前提和标志之一来考虑。 |

| Abstract: | According to geochemical characteristics and space-time distribution of adakites,the deposits related to adakites in China can be divided into two major types respectively occurring in orogenic belts and within continental blocks,as well as several mineralization belts or sub-belts. The deposits in orogenic belts distribute in the Paleo-Asian Oceanic metallogenetic belt,Qinling-Qilianshan-Kunlun metallogenetic belt,Circum-Pacific metallogenetic belt and Neo-Tethys metallogenetic belt;while the deposits within continental blocks distribute in East China metallogenetic belt,Qinghai-Tibet Plateau metallogenetic belt and southeastern Tibet-southwest Sichuan-northwest Yunnan metallogenetic belt. The close association of adakites with mineralization may have an important implication for prospecting of related deposits based on occurrence of adakites. Considering current situation and future demand of prospecting large-sized deposits,the strategic,short-term and long-term objectives should be made in the prospecting of copper,gold,molybdenum and silver deposits in China,especially in enhancing prospecting consciousness in the Paleo-Asian Oceanic Orogenic belt and Gandise Orogenic belt,and the occurrence of adakites might be an indicator for finding related deposits. |
