| 摘 要： | 辽东裂谷内的辽河群南带为玉石成矿有利部位,大石桥组三段为主蕴矿层,其层间断裂为主要的布矿和储矿构造.辽河期黑云二长花岗岩及其脉岩与富镁质碳酸盐岩接触部位对成矿最有利.玉石产于中-高温、高压、SiO2不饱和的封闭型地质环境中,为层控型热液交代为主的复合成因矿床.

| Abstract: | Liaohe Group located in East Liaoning Rift is favorable for jade formation. Upper Dashiqiao Formation is the main host rock of jade, and interlayer fractures are the main ore-controlling structures as well as the host structures. The most favorable locations for jade formation are contact zones between biotite monzonitic granite dykes and Mg-rich carbonate rocks. The jade deposits were formed in a mid-to-high-temperature, high-pressure and SiO_2-unsaturated geological condition. These deposits are polygenetic characterized by stratabound hydrothermal metasomatism. |
