胶东地区“岩浆核杂岩”隆起－拆离带岩浆期后热液蚀变成矿
Hydrothermal Alteration Metallogenesis in the Determination Zone of a“Magmatic Core Complex”Upheaval-detachment Structure,Jiaodong
摘要
Abstract
Jiaodong gold mine is one of the most largest gold deposits related with granites in the world.This paper points out that Jiaodong gold deposits formed in the inland after plate collison in Mesozoic,and that they belong to “Diwa”tectonic areas.The authors substitute a new concept of “magmatic core complex”for “meta-morphic core complex”.There are the “magmatic core complex”in Jiaodong ,which posses granite core (1 80-1 30 Ma),metamorphic wall-rock (2,500 -1 ,300 Ma)and their lid of volcanic sedimentary basin.Shear zones are located among the granites,metamorphics and sedimentary beds;the shear zones between the granite core and the metamorphic wall rocks return into the detachment fault with wide toughness-brittleness cataclastic rocks at the side of granites;therefore,the Jiaodong gold deposits of phyllic alteration form by the post-magmat-ic hydrothermal liquid in fault cataclastic rocks(1 20 -1 00 Ma).The Jiaodong “magmatic core complex”struc-ture perhaps is a common geologic phenomenon at actic Mesozoic in China.关键词
