摘 要: | 本文通过对胶南-文荣碰撞带东段,即文登南部陆-陆碰撞带地质特征研究,探讨了Ag→Au,Ag→Au→Au,Pb,Zn→Au,Cu这一明显的矿化分带性与碰撞机制的关系,详细研究了碰撞带中石英包裹体特征,尤其是深入研究了石英包裹体中H2O和CO2含量变化特征与碰撞带中挤压构造及伸展构造耦合关系,提出了碰撞驱动流体与成矿的认识。

Abstract: | Through the research on the geological characteristics of the eastern section of Jiaonan_Wendeng collison zone,i.e.the southern Wendeng continent_continent collision zone,the authors discuss the relationship between the evident zonal mineralization distribution from Ag through Au_Ag,Au,Au_Pb_Zn to Au_Cu and collision mechanism,research detailed features of quartz inclusions in collision belt,especially the coupling relation of varing features of H 2O and CO 2 contents in quartz inclusions to compressive and extensional structures in the collision zone,and further present the recognition about the mineralization of fluid drived by the collision. |
