稀有金属分散元素对于发展我国原子能工业、半导体、无线电、喷气飞机和火箭等尖端科学技术具有重大意义。最近党号召大力加强这方面的勘查工作,以能迅速保证我国工业建设对稀有金属分散元素日益增长的需要。地球物理勘探方法过去在这方面是有一定效果的,如曾使用航空放射性测量在广东发现一个巨型砂钛矿,曾使用磁砖圈定与接触式钨矿有关的矽 Disperse elements of rare metals for the development of China’s atomic energy industry, semiconductors, radio, jet aircraft and rockets and other cutting-edge science and technology of great significance. Recently, the Party called for strengthening the prospecting work in this area so as to promptly ensure that the industrial construction in our country needs a growing number of scattered elements in rare metals. Geophysical prospecting methods used to be effective in this respect. For example, giant megaliths were found in Guangdong using aeronautical radioactivity measurements, and tiles were used to delineate the silicon associated with contact tungsten
