metallogenic stage

The mineralization system was a semi-closed state in the main metallogenic stage .

在主要成矿阶段，体系处于一种半封闭状态。

It follows a certain sequence and is consistent with the corresponding metallogenic stage that the metallogenic elements of the vein hydrothermal gold deposits separate out the precipitation .

脉状热液金矿成矿元素析出沉淀遵循一定的顺序，并与相应的成矿阶段相一致。

With precipitation of As and Au , silicification took place at the early metallogenic stage at relatively high temperature ( 200 ~ 300 ℃), forming silicified rocks .

硅化作用主要在成矿早期，温度较高（200～300℃），砷、金主要在这一阶段析出。

Therefore , the ore bearing fluids migrated up , injected and aggregated along these structural expanding belts during the main metallogenic stage , forming a series of structural altered type and vein type deposits .

主成矿期含矿流体沿构造扩容带贯入、聚集和成矿，形成一系列构造蚀变岩型、脉型矿体。

The gold-mineralization can be divided into three stages that are gold activation stage , gold initial enrichment stage and gold metallogenic stage which are respectively related to the ductile , ductile-brittle and brittle shear strains .

金矿化经历了金活化、金初始富集和金成矿三个阶段，并分别与韧性、韧脆性、脆性剪切变形相对应。

So it is conferred that movement way in which epigenic groundwater enters into metallogenic solution at metallogenic stage is turbulence movement driven by topographic potential , magmatic residual heat and gradients of temperature and pressure of high temperature and high pressure fluid .

因而推论成矿期外生地下水进入成矿热液的运动形式是在地形势驱动及岩浆余热及高温高压流体温度、压力梯度驱动下的湍流运动。
