| 摘 要： | 湘黔桂相邻区中、新元古界浅变质岩系的含金建造多为斜坡-盆地相、深水-较深水、远源-中源的浊流沉积,常富含凝灰质、碳质及硫化物,属于活动大陆边缘地壳强烈拉伸环境的产物,形成于扬子古大陆裂陷和再度裂陷时期.中、新元古代火山活动为其提供了丰富的成矿物质,多数成为原生含金建造,个别成为衍生含金建造.这些含金建造在形成之后,先后遭受了区域埋深变质作用、区域动力变质作用,以及脆韧性、脆性剪切作用,最终形成了变质细碎屑岩型金矿. |

| Abstract: | In the Meso-Neoproterozoic light metamorphic rock series in the boundary of Hunan,Guizhou and Guangxi regions,most of the Au-bearing sedimentary sequences are turbidity current sediments,formed in basin or slope facies,deep-water or deeper-water depositions.Their materials are far-resource or mid-resource,and are often enrich-tuffaceous,carbonaceous and sulfide rocks.These sedimentary sequences are formed in active margins where crust had been strongly stretched druing the rifting of the Yangtze block.There... |
