摘要
花岗岩浆的铝碱相对饱和程度不仅直接影响岩浆结晶演化的途径和相关系,而且是决定金属元素在岩浆体系中不同物相间分配以及岩浆气液化学性质的重要因素,并在一定程度上制约着岩浆体系中成矿元素的分散或者集中以至矿化的类型和规模.
The degree of alumina-alkali saturation in granite magma is an important factor that not only directly influences the paths and the phase relations of the magmatic crystallization evolution, but aiso determines the distribution of the metallic elements in various phases in magma series and chemical properties of magmatic gas-liquid phase. It also controls the dispersion or the concentration of the ore-forming elements in magma series to a certain degree, or even the type and scale of their mineralization.
