沉积型铝土矿预测方法及其影响因素——以贵州省铝土矿为例

以全国矿产资源潜力评价技术要求为基础,以贵州省铝土矿预测方法为实例,在简述国内沉积型铝土矿矿床类型、特征和预测方法的基础上,重点论述了地质单元法、网格单元法中划分预测单元、拟选预测要素和赋值的方法,以及地质填图精度、矿床特征、地-物-化-遥等信息对矿产预测的影响。该网格单元法考虑因素较全面,应用信息较充分,预测精度达到了矿体-矿床级。

The prediction methods and its influencing factors of the sedimentary bauxite resource,taking bauxite resource of Guizhou Province,China as an example

According to the technical requirements of national mineral resources potential evaluation, this article, taking the bauxite resource prediction in Guizhou Province as the example, this paper focuses on the prediction units division of the geological-unit and grid-unit method, the selection of essential factors for prediction, assigning value to essential factors as well as discussion of the influence of geological mapping scale, the characteristics of mineral deposit, geophysical and geochemical remote sensing information on mineral resource prediction, with the introduction of mineralizing types and its characteristics, prediction methods of sedimentary bauxite resource in China. This grid-unit method has considered the most essential prediction factors, and its accuracy has reaches to each single orebody or deposit.
