热液矿床中,流体的沸腾和混合导致溶液温度下降和溶质离子浓度的变化,被认为是矿床矿物沉淀的一个基本机制。近年来许多学者都强调流体沸腾、混合作用和矿物沉淀之间的关系。这两种作用常常使得成矿热液体系发生物理-化学参数的突变或临界转变,对热液矿床成矿元素进行搬运、聚集和沉淀的过程都具有重要的意义。在自然界中,与液态不混溶作用相关的成矿作用主要包括3类:①岩浆液态分离作用把岩浆房分离成两个不混熔的部分,即岩浆房上部的矿浆(含
Hydrothermal deposits, fluid boiling and mixing lead to the solution temperature drop and solute ion concentration changes, is considered to deposit mineral deposits is a fundamental mechanism. In recent years, many scholars have emphasized the relationship between fluid boiling, mixing and mineral precipitation. These two kinds of effects often make sudden or critical changes in the physico-chemical parameters of the hydrothermal fluid system and are of great significance to the process of transporting, aggregating and precipitating ore-forming elements in the hydrothermal deposit. In nature, the mineralization related to the immiscibility of liquid mainly includes three types: (1) The magmatic liquid separation separates the magma chamber into two immiscible parts, that is, the ore pulp in the upper part of the magma chamber
