对河北及山东4个金矿床中的交代成因钾长石与钠长石进行了天然热发光的研究,它们包括两种类型:一种为蚀变岩型(胶东夏甸金矿,河北高家店金矿);另一种为石英脉型(胶东金翅岭金矿,河北金厂峪金矿)。经研究发现,当接近矿化地段时,钾长石与钠长石天然热发光峰值增高,尤其是在富矿地段突然升高;在破碎带或受动力影响的长石,热发光峰值突然降低。因此长石天然热发光可用以指示交代作用,矿化作用与成矿后动力作用的空间位置,因而可以作为成因与找矿标志。
The natural thermoluminescence of metasomatism and albite from the four gold deposits in Hebei and Shandong Provinces are studied. They include two types: altered rock type (Jiaodong Xiadian Gold Mine, Hebei Gaojia Shop gold); the other for the quartz vein type (Jiaodong Gold Ridge Gold Mine, Hebei Jinchangyu gold). The study found that when close to the mineralized areas, the natural peak of K-feldspar and albite increased, especially in the rich ore section suddenly increased; in the fracture zone or affected by feldspar, the peak of thermal emission suddenly decreased. Therefore, the feldspar natural thermal luminescence can be used to indicate the role of metamorphism, mineralization and the spatial location of post-metallogenic dynamics, which can be used as a cause and prospecting markers.
