随着“四化”建设的发展,铝的需求量与日俱增,铝土矿的找矿勘探日益提到重要的地位。笔者在近年工作中,摸索出这方面一些经验和体会,写出来供大家参考。一、铝土矿的地层找矿标志我国铝土矿资源丰富,南北方的主要矿床类型,均产于基底长期侵蚀的古风化面上,属沉积矿床,层位稳定。由于现阶段技术经济条件的限制,目前开采深度均不超过垂深100米,多为露采。故寻找浅富近易矿床是我们的任务。为此,要优先选择在地层平缓的地区找矿,这种地区有足够大的赋矿
With the development of the “four modernizations”, the demand for aluminum is increasing day by day, and prospecting for bauxite is increasingly referred to an important position. In recent years, I worked out some experiences and experiences in this area and wrote them out for your reference. First, the stratigraphic prospecting symbol of bauxite China is rich in bauxite resources, the main types of deposits in both north and south, are produced in the long-term erosion of the basement of the ancient weathering surface, is a sedimentary deposit, strata stable. Due to the technical and economic conditions of the current stage of the restrictions, the current mining depth are not more than 100 meters deep, mostly open-cut. Therefore, to find shallow Fu Yi deposits is our task. To this end, priority should be given to prospecting in areas with gentle strata, where there is enough ore
