冈底斯东段汤不拉斑岩型钼(铜)矿床成矿模式
Mineralization Model for Tangbula Porphyry-Type Mo (Cu) Deposit in East Gangdisi, Tibet
-
摘要: 汤不拉斑岩型钼(铜)矿床地处冈底斯构造成矿带东段,具有优越的成矿条件。通过系统研究分析其成矿地质背景、成岩成矿时间、成矿物质来源、成矿作用和矿体赋存状态等,建立成矿模式。冈底斯斑岩型铜矿床成岩成矿时间基本集中于喜山期,形成作用主要与新特提斯洋壳向北俯冲到拉萨地体下有关,赋矿岩体多为中酸性钙碱系列具有埃达克质岩特征的侵入岩。该矿床成矿模式的建立对其在区域上的成矿预测及区域成矿模式的建立具有现实意义。

Abstract: Located east to Gangdisi tectonic metallogenic belt, Tangbula porphyry-type Mo (Cu) deposit boasts advantageous metallogenic conditions. The article analyzed the geological background of mineralization, the time of digenesis and mineralization, the source of ore-forming materials, the process of mineralization, the state of orebodies occurrence, and finally established a metallogenic model. Results have shown that the digenesis and mineralization of Gangdisi porphyry-type copper deposit occurred intensively in the Himalayan period, the formation is related to the northward subduction of Tethyan oceanic crust into the bottom of the Lhasa terrane. The ore-bearing rock are mainly intrusive rocks of intermediate acid calc-alkaline rock series with characteristics of adakitic rock. The mineralization pattern is of practical significance to regional mineralization forecast and metallogenic model establishment.-
