找出与矿体有关的原生晕和次生晕,这是地质工作中物化探工作的重要任务之一。可是,次生晕和原生晕的成果要通过野外取样和室内的各种测试之后才能得出,这往往要经过数月甚至要跨年度才能完成。为了提高效率,我们研究所进行了“So_2气体测量矿法”(简称 ST—So_2法)的研究。到1981年8月底,这项实验研究取得了初步的、但却是明显的成果。样品只要含有自然硫或金属硫化物,那怕少得连一般光学显微镜都难以发现,焙烧后也会产生一定量的二氧化硫气体。反之,假若我们通过大量的实验研究,弄清了在一定条件下
Identifying the primary halo and secondary halo related to the orebodies is one of the important tasks of geophysical and geochemical exploration in geological work. However, the results of secondary halo and primary halo can only be obtained after field sampling and indoor tests, which can take months and even years to complete. In order to improve the efficiency, our institute has carried out the research on “So_2 gas measuring mine” (ST-So_2 method for short). By the end of August 1981, this experimental study had achieved initial but significant results. As long as the sample contains natural sulfur or metal sulfides, even less common optical microscope are difficult to find, will produce a certain amount of sulfur dioxide gas after firing. On the contrary, if we through a large number of experimental studies, to clarify under certain conditions
