长石是许多侵入岩、变质岩和交代岩的主要造岩矿物。很多若者经研究查明,长石是许多稀有元素的载体矿物,有时还是它们的富集矿物。众所周知,造岩矿物和付矿物成分中的许多稀有和分散元素在含量上的差异,可用来说明岩石的成因性质及其可能的含矿性。同时,确定侵入体造岩矿物中元素的分配参数,也具有相当重要的意义。载体矿物中杂质元素的平均含量通常被作为原始岩浆中杂质元素含量的上限。因此,以相当广泛的实际资料可靠地确定造岩矿物中杂
Feldspar is the major rock-forming mineral of many intrusive rocks, metamorphic rocks and metasomatic rocks. Many studies have shown that feldspar is a carrier mineral for many rare elements and sometimes also their mineral rich. It is well-known that the differences in the content of many rare and dispersive elements in rock-forming and pay-mineral compositions can be used to illustrate the genetic nature of the rock and its possible mineralization. At the same time, to determine the distribution parameters of intrusive rock-forming minerals also has a significant meaning. The average content of the impurity elements in the support minerals is usually used as the upper limit of the impurity element content in the original magma. Therefore, a wide range of practical data to reliably determine the miscellaneous rock-forming minerals
