摘要
为了指导找矿 ,通过近年来找矿预测获得的新突破和积累的较新测试资料 ,对二台子金矿床作出进一步的认识和总结 ,在探讨矿床成矿大地构造背景的基础上 ,提出矿床所在盆地的容矿岩系发育模式。在矿床成矿作用演化研究中 ,进一步阐述了矿床形成经历的同生与后生两次成矿作用 ,分别与秦岭造山带南北陆块俯冲碰撞造山导致被动大陆一侧局部出现伸展断陷式盆地和转入陆内逆冲推覆造山的构造 -岩浆活动密切耦合。
In recent years,the geologic-prospecting and exploration of Ertaizi gold deposit have made great progress.The discovery of a few considerable ore bodies within the framework of the mining areas has accumulated new material for the study on geologic-geochemistry of Ertaizi gold deposit.On the basis of our predecessors work,the geologic-structural setting of production of gold deposit are further expounded,including dividing stage and phase into ore-forming process of Ertaizi gold deposit.The genesis and prospecting of gold deposit are also well probed.
