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OA
Geochemical Characteristics and Significance of Inclusions and Stable Isotopes in Yangchu area in Qixia City in Shandong Province
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.
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,volcan-ic 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 anal-ysis 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 poly-metallic deposits in the region has been preliminarily identified,and a mineralization model has been crea-ted.
