根据实际资料,与金矿成矿关系显著的三个时代的岩浆岩,一是加里东期花岗岩,主要分布在华南加里东地槽区,岩性为斑状花岗闪长岩及花岗斑岩、石英斑岩等。如大宁岩体——黑云母闪长岩、斑状花岗闪长岩金的平均含量分别分9×10-9、3.7×10-9。岩体与寒武系地层的接触带及附近形成龙水、张公岭金矿床。二是海西期岩浆岩主要分布于我国西北与东北部的海西褶皱带中。岩体控矿绝大多数为海西中晚期的斜长花岗岩、花岗闪长岩、二长花岗岩等呈岩基、岩株、岩枝产出。经统计,区内已发现50余处金矿床(点),大多数产于岩体之中或接触带附近。三是燕山期的构造岩浆活动,我国许多内生金矿都与此次活动密切相关,特别是东部地区。
According to the actual data, significant relation with gold mineralization of the three times of magmatic rocks, one is CALEDONIAN GRANITE, mainly distributed in the South China Caledonian geosynclinal area, lithology is porphyritic granite flash diorite and granite porphyry and quartz porphyry. If the average content of Daning rock biotite diorite, porphyritic granodiorite gold were divided into 9 * 10-9 and 3.7 * 10-9. The formation of water dragon, Zhanggongling rock gold deposits and Cambrian strata of the contact zone and nearby. Two is the western part of the western part of China's northwest and northeast. Rock mass controlled mine the vast majority of mid late Variscan plagiogranite and granodiorite flash diorite, monzogranite is rock, rock plant, rock branch output. Statistics, more than 50 gold deposits have been found in the area (point), most of them occur in the vicinity of the rock mass or the contact zone. Three is the Yanshan period of tectonic magmatic activities, many of the gold deposits in China are closely related with the event, especially in the eastern region.
