沉积型矿产预测工作中预测要素变量的优选——以贵州省铝土矿为例

Optimization of Predicted Factor Variable in the Sedimentary Mineral Resource Prognosis

矿产预测是矿产资源潜力评价的最终目标和最重要环节。预测要素选取是矿产预测的重中之重,其主要是在典型矿床预测模型的基础上,初步拟选预测要素变量,通过分析已知矿床(点)与预测要素之间的关系,通过定性和定量分析,从而优选出对成矿有利、贡献较大的因素作为预测要素。

In this paper,the lithology and geochemistry characters of carbonate lens which occurred in Jiumenchong formation,Lower Cambrian is narrated,the analysis shows that the genesis is unusual sediment-crust-mantle mixed hydrothermal exhalative sediment.New information and acknowledge are afford for the searching of crust-mantle mixed hydrothermal mineral and the study of sedimentary environment in this period.
