山东栖霞杨础地区包裹体及稳定同位素地球化学特征及其意义

Geochemical Characteristics and Significance of Inclusions and Stable Isotopes in Yangchu area in Qixia City in Shandong Province

摘要:

栖霞杨础地区属于胶辽隆起区，该地区广泛发育太古宙变质深成岩，元古宙变质表壳岩，中生代沉积岩、火山岩、酸性侵入岩以及新生代沉积物，主构造线呈NE向，是主要的控矿构造，其内赋存有众多中小型金矿床。本文通过对该区域内新发现的金及多金属矿化点的矿（化）体的特征及部分矿石的流体包裹体、同位素等特征分析，初步查明了该地区金及多金属矿床成因并建立了成矿模式。

Abstract:

Yangchu area in Qixia city belongs to Jiaoliao uplift area. It is widely developed with Archean metamorphic plutonic rocks, Proterozoic metamorphic crustal rocks, Mesozoic sedimentary rocks, volcanic rocks, acidic intrusive rocks and Cenozoic sediments. Main structural line is in the NE direction and is the main ore controlling structure. There are many small and medium-sized gold deposits. Through analysis on the characteristics of newly discovered gold and polymetallic mineralization points in the region, as well as the fluid inclusions, isotopes, and other characteristics of some ores, the genesis of gold and polymetallic deposits in the region has been preliminarily identified, and a mineralization model has been created.
