| 摘 要： | 兰坪盆地的演化受控于盆地所处的构造背景,经历了中三叠世至早侏罗世的陆内裂谷盆地、中-晚侏罗世的拗陷盆地、白垩纪的前陆盆地、古新世-中新世的走滑盆地。盆内成矿与盆地性质密切相关,陆内裂谷盆地阶段是重要的成矿期,具热水沉积矿床特征;拗陷盆地阶段多形成铜多金属矿床;前陆盆地阶段为喜山期的成矿作了物质准备;走滑盆地阶段,由于推覆构造活动强烈,深部流体和浅部红层中的盆地流体的混合,提供了大量的矿物质,并就位于构造圈闭中,形成如金顶铅锌矿等大型矿床。 |
| 关 键 词： | 盆地演化 成矿特征 推覆构造 金顶铅锌矿 |

| Abstract: | The evolution of Lanping Basin is subjected to its tectonic background,which experienced intracontinental rift basin stage from Middle Triassic to Early Jurassic,depression basin stage from middle to late Jurassic,Foreland basin in Cretaceous and Strike-slip basin from Palaeocene to Miocene.Mineralization was Closely related to the Basin nature,the intracontinental rift basin stage was the important mineralogenetic epoch,the mineral deposit structure with the character of hydrothermal ore deposit.The copper... |
