Abstract: Selenium as a dispersed element is very low in the earth. The study on selenium deposits is poor resulting in issues in exploring and developing selenium deposits. This paper, based on selenium geochemistry and deposit types, studies the selenium in soils and plants of biosphere, combined with its global demand and prices, discusses the situation and finds the supply & demandconflict,which makes study on selenium urgent,especially on its source and concentrating. This paper can provide reference for exploration of selenium deposits.

摘要： 通过对硒的地球化学性质以及硒矿床类型的分析，对生物圈中土壤硒和植物硒的研究，同时结合硒在国际市场以及国内的需求量和硒的价格分析，对硒的现状有了初步的了解，也发现硒矿资源的供求矛盾，使得硒矿的研究更加迫切。因此，需要加强硒矿资源的研究，特别是对硒矿来源和富集的分析和研究，为指导下一步的找矿提供科学理论。
