矿产资源是社会生产发展的重要物质基础.现今世界每年开采出的原矿石达1000亿吨之多.面对2000年矿物原料需求量的增长形势,各国都认识到,矿产普查难度日益增大,找矿效果下降,成本明显提高,能取得充裕和廉价矿物原料的时代,可说已经一去不复返了.因此,促使地质学家在开展矿产普查的过程中,积极探索新的途径,来解决人类对矿物原料不断增长的需要,导致矿产普查工作出现了一些值得注意的动向.一、加强普查找矿,为国民经济的发展提供可靠的矿物原科基地
Mineral resources are an important material basis for the development of social production. In the world today, as many as 100 million tons of ore are mined each year. Facing the growth in the demand for mineral raw materials in 2000, countries have realized that the difficulty in the general survey of mineral resources is increasing. The era of declining ore-finding effect and the obvious increase in costs, and the era of abundant and cheap mineral materials, can be said to be gone. Therefore, geologists are actively exploring new ways to carry out mineral surveys. Solving the growing demand for mineral raw materials by humans has led to some noticeable trends in the mineral survey. First, strengthening the search for minerals and providing a reliable mineral base for the development of the national economy.
