| 摘 要： | 普兰店元台逆冲推覆构造为典型双重逆冲构造，以上叠式扩展而成。在自南向北逆冲过程中，形成褶皱推覆体，滞后断层，撕裂断层，反冲断层，并进一步形成构造窗和飞来峰。推覆构造形成于 J2-J3，逆冲推覆后期，花岗闪长斑岩沿逆冲推覆构造就位，其所携带的成矿热液在有利部位富集成金矿。

| Abstract: | Yuantai reverse thrust nappe structure at Pulandian is a typical double reverse thrust structure with a overstep thrust propagation, which includes a series of fault nappes,lag faults,rip-up faults,recoil faults,klippes and windows,etc. The nappe structure formed in Mid-Late Jurassic. During the late stage of reverse napping,granodiorite porphyry emplaced along the nappe structure and hydrothermal ore-forming solution accumulated and formed gold deposits at favourable positions.Yuantan gold deposit was strickly controlled by structures ,had a very close correlation with the reverse nappe structures, and in space,closely related with granodiorite porphyry.So it has great potencial to find out deep blind orebodies below the nappe or the same type of gold orebodies as Yuantai gold deposit around granodiorite porphyry distribution area. |
