摘要
在全国金矿资源潜力评价基础上,将全国金矿矿产评价模型总结为12类:与中深成侵入岩有关的热液型、破碎蚀变岩型、斑岩型、矽卡岩型、海相火山岩型、陆相火山岩型、微细浸染型、变碎屑岩地层中热液型、绿岩建造型、砂金型、风化壳型和砾岩型。其中,以与中深成侵入岩有关的热液型、破碎蚀变岩型、微细浸染型为主,其预测资源量约占总预测资源量的38%,21%和14%。根据资源量的空间分布及成矿地质背景划分了55个金矿成矿区带,通过对不同成矿区带对预测资源量、累计查明资源储量统计分析,金矿主要集中分布于胶东、华北地台南缘、西秦岭、东秦岭、辽东、滇黔桂、哀牢山成矿带等。根据金矿的成矿地质背景,结合金矿资源潜力及近年来金矿勘查进展,对下一步的工作部署提出参考建议。
Based on the national gold resource potential assessment,authors classify the predictive types of gold deposit in China into 12 categories,such as hydrothermal type associated with the intrusive rock,cracked-alteration type,porphyry type,skarn type,marine volcanic type,continental volcanic type,micro-gruanlar disseminated type,hydrothermal type located in matamorphic clastic rocks,greenstone formation type,placer gold type,weathering crust type and conglomerate type gold deposits.Among these deposits,the first three types are dominated with the percent of predictive gold resources respectively as 38%,21% and 14% in turns.According to the spatial distribution and metallogenic geological settings of gold deposits,55 gold metallogenic areas（zones） are determined.The gold deposits mainly concentrates in such areas as Jiaodong,southern edge of North China platform,western Qinling,eastern Qinling,the eastern Liaoning,the triangle area of Guizhou-Guangxi-Yunnan and Ailaoshan etc.According to the geologic background of gold deposits,combining with the national gold potential assessment and recent gold deposit prospecting progress,authors put forward some advices for the further exploration program.
