元素钨自1783年被发现,至今已近200年.从矿床学角度来看,钨可说是一个研究程度较高的矿种,但钨的地球化学许多方面的资料,相对来说十分缺乏,并且很多老数据(特别是1946年以前的)可能是错误的.由于早期缺少精确分析普通岩石和矿物中钨含量的方法,因而也就无法正确认识钨的地球化学行为. 过去十年间,矿床成因的许多领域都认为发生了重大革命,包括钨矿在内.对钨的最主要工业矿床的成因,长期认为是与花岗岩类侵入体直接或间接相关,传统的占优势的钨矿成因理论是
Tungsten has been found for nearly 200 years since 1783. Tungsten can be said to be a highly studied mineral from the perspective of ore deposit, but many aspects of tungsten geochemistry are relatively scarce, And many of the old data (especially before 1946) may be wrong.Due to the early lack of accurate methods for the accurate analysis of tungsten in normal rocks and minerals, the geochemical behavior of tungsten can not be correctly understood.In the past ten years, the genesis of the deposit Many believe that major revolutions have taken place, including tungsten, and that the genesis of the most important industrial deposits of tungsten has long been thought to be directly or indirectly related to granite intrusions and that the traditional theory of the genesis of tungsten is
