摘要
胶东存在中深成和浅成两类脉型金矿。定量统计模型研究发现 ,形成于挤压地球动力学环境的中深成脉型金矿 ,成矿深度相对深 ,规模大 ,矿化强 ;形成于拉张地球动力学环境的浅成脉型金矿 ,成矿深度相对浅 ,规模小 。
There are two types of vein type gold deposits(mesogenic and epigenic vein type gold deposits) in the eastern Shandong.According to the study of quantitative statistics model,we find that the mesogenic vein type gold deposits which formed in compressional geodynamic enviroment have relatively deep mineralization depth,large scale and strong mineralization;whereas the epigenic vein type gold deposits which formed in tensional geodynamic enviroment have relatively shallow mineralization depth,small scale and weak mineralization.
