正确品位的获得,是勘探各种类型矿产时的主要問题之一。而正确品位的获得,則视取样方法能否代表该类矿床之特性而定。因此取样方法的正确选择是地质勘探工作中之主要任务之一。这里仅谈一谈在勘探花岗岩伟晶岩脈的过程中,对不同结构类型的花岗伟晶岩矿脈的采样方法。花岗伟晶岩矿脈与其他各种类型矿脈含矿主要不同之处,就在于花岗伟晶岩脈内含有用矿物之情
The acquisition of the correct grade is one of the major problems in the exploration of various types of minerals. The correct taste, depending on whether the sampling method can represent the characteristics of such deposits may be. Therefore, the correct choice of sampling method is one of the main tasks in geological prospecting. Here only to talk about the exploration of granite pegmatite process, the different types of structural types of granitic pegmatite vein sampling method. The main difference between the granitic pegmatite veins and other types of veins and ore deposits lies in the fact that the granitic pegmatite vein contains minerals
