对花岗伟晶岩类型矿床的评价问题,是一个细緻而复杂的问题。它的评价和其他类型矿床的评价一样,受许多条件因素的控制,如国家的须要,开采的技术条件,矿床的特征和该地区之自然地理位置等,所以对任何矿床的评价(无论初步评价和最终评价)的结论,都是有时间性的。有些矿床可能在今日评价之理论知识基础上认为无工业意义,但几年之后随着地质知识之丰富,实际材料的掌握,对评价工作又有了新的认识。所以对任何矿床的评价,都会随着时间的不同,而有各个时期不同的标准。过去的一些地质工作者在评价花岗伟晶岩矿脈
Evaluation of the granitic pegmatite deposit is a delicate and complicated issue. Its evaluation, like that of other types of deposits, is governed by many conditions, such as the needs of the country, the technical conditions of exploitation, the characteristics of the deposit and the geographical location of the area, etc. Therefore, the evaluation of any deposit And final evaluation) are conclusive. Some of the deposits may not be of industrial significance based on the theoretical knowledge of today’s assessment. However, with the abundance of geological knowledge and mastery of actual materials after a few years, a new understanding of evaluation has been obtained. Therefore, the evaluation of any deposit will be different over time, but different standards in different periods. Some past geologists are evaluating the granitic pegmatite veins
