青海省都兰县迈龙地区金多金属矿地质特征及矿床成因分析
|
摘要
该区大地构造位置位于东昆仑前峰弧南侧复合拼贴带东段的北部。该带为早古生带昆仑大洋板块向柴达木板块俯冲而形成的岩浆弧带。区内主要地层以晚太古—古元古代金水口(岩)群构成其结晶基底。该区地史演化漫长,地质构造复杂,岩浆活动频繁而强烈。是省内著名的金、铁多金属成矿带,素有"金腰带"之称。成矿条件优越,成矿潜力较大,具有良好的找矿前景。
The tectonic location of this area is located in the northern part of the eastern part of the compound collage zone on the southern front of the East Kunlun arc. The belt is a magmatic arc formed by subduction of Kunlun oceanic plate to Qaidam plate in Early Palaeozoic era. The main strata in the area consist of the late Archean Paleoproterozoic Jinshui estuary(rock) group, forming the crystalline basement. The geological evolution of long, complex geological structure, magmatic activity is frequent and strong. It is a famous gold and iron polymetallic metallogenic belt in the province, and is known as the "golden belt". The ore-forming conditions are superior and have great potential for mineralization.
