大量普查找矿工作表明,我省钨矿的形成与燕山早期黑云母花岗岩具有十分明显的关系,钨矿的分布与该期岩体有着依存关系,钨的成矿作用与该期次岩浆的成岩作用在时间上、空间上紧密相随。然而,并不是所有燕山早期黑云母花岗岩与钨成矿作用都很明显,而是在岩浆演化结晶分异到特定的阶段上才有钨矿床的形成。大量资料说明:钨成矿明显的岩体(以下称钨成矿岩体)在岩石化学成分上具有高硅、富铝、碱量大、贫基性组分的特点,而随SiO_2的
A large number of census prospecting work shows that the formation of tungsten mines in our province has a very obvious relationship with the early Yanshan biotite granite. The distribution of tungsten mines is dependent on the rock mass and the mineralization of tungsten is associated with the diagenesis The role of time, space closely with each other. However, not all of the early Yanshanian biotite granites and tungsten mineralization are obvious, but in the magma evolution crystallization differentiation to a specific stage of the formation of tungsten deposits. A large amount of data shows that the obvious tungsten mineralization (hereinafter referred to as tungsten ore-bearing rock mass) has the characteristics of high silicon, aluminum-rich, alkali mass and poor base components in petrochemical composition,
