| 摘 要： | 大龙现代热泉是沿沘江断裂带分布的众多温泉之一,其喷流-沉积成矿作用较为直观地展示了热泉堆积泉华成矿过程,佐证了新生代在兰坪盆地热泉成矿的可能性和普遍性。热泉"热循环"作用形成三种成矿模式:喷出贯入陷沟和湖泊形成致密块状、角砾状矿体——兰坪"金顶式"Pb-Zn矿床;于构造带中沿一系列构造界面形成脉状矿体——兰坪"白秧坪式"Ag-Pb-Zn多金属矿床;喷流的地表沟谷形成热泉型——云龙"大龙式"Ag-Pb-Zn多金属矿床(低品位)。

| Abstract: | Dalong present hot pring is a hot spring along Bijiang river fault zone. The effusion - sedimenta- tion metallogenesis of it shows the objective metallogenetic process of hot spring accumulation sinter and confirms the possibility and popularity of Cenozoic hot spring metallogenesis in Lanping basin. The ＂thermal cycle＂ of hot spring has 3 metallogenetie models, ie, 1. effusion - injection fault trough ; 2. lake compact massive, breccia ore body--Pb - Zn deposit of Lanping ＂Jinding type＂ ; 3. veined ore body along a series of structural surfaces in structure zone--Ag - Pb - Zn multimetallic deposit of Lanping ＂Baiyan gping type＂. |
