新西兰阿尔卑斯南部是一个活动的上升山脉带.在靠近澳大利亚-太平洋板块边界的阿尔卑斯断裂附近,该带特显示出热异常.在该隆起带中普遍出现流体运动,导致金属矿脉形成.金矿化产在绿片岩相岩石中,而铜富集在阿尔卑斯断裂附近的角闪岩相岩石中,并呈较年轻的矿脉。在这复杂的热液体系中,金属的搬运和沉积受控于上升变质流体和向下渗入的大气流体之间相互作用,变质流体与围岩石墨片岩发生平衡作用,并使变质流体相受到还原,流体中大气水的混合和渗入使流体氧的活性增高而硫的活性降低,氧化的大气水在向下渗入时被加热并溶解了铜,当流体变得较还原时铜便开始沉淀.因此,在热液体系中部,特别是在阿尔卑斯断裂附近渗透性高的断裂岩中铜含量逐渐增高.
The southern New Zealand Alps is an active upwelling belt that shows thermal anomalies near the Alps fault near the Australia-Pacific plate boundary where fluid movements generally occur, leading to the formation of metallic veins. In greenschist facies, copper is enriched in amphibolite facies near the Alps fault and appears younger. In this complex hydrothermal system, metal transport and deposition are controlled by the interaction between the ascending metamorphic fluid and the infiltrating atmospheric fluid, and the metamorphic fluid balances with the surrounding rock graphite schist and renders the metamorphic fluid phase reduced , The mixing and infiltration of the atmospheric water in the fluid increases the activity of the fluid oxygen and the activity of the sulfur, the oxidized atmospheric water is heated and dissolved in the infiltration downwards, and the copper begins to precipitate as the fluid becomes more reduced In the middle part of the hydrothermal system, especially in the high-permeability fracture rocks near the Alps, the copper content gradually increased.
