逻辑信息法优化及其在湘黔汞矿带南段资源潜力预测中的应用

本文阐述逻辑相息法的某些改进。引入有利度和信息度作为评价对象的主要指标,建立起湘黔汞矿带南段三态逻辑信息模型。讨论了汞矿资源量同有利度的相关关系,达到了定位定量预测的目的。文章指出:湘黔汞带南段,经多年地质勘探工作已基本探明,但还有一定的资源潜力。本次研究获得的有利成矿地段,有的就是已知矿点或在已知矿床外围及延伸部位,可望增加储量。另外一些地段因矿小、分散和埋藏过深,凭目前技术经济条件,尚难发现和提供工业利用,可视为潜力资源,供长远规划参考。

An Improvement in the Logical Information Mcthod and its Application to the Potential Resources Calculation of the Southern Section of the Xiang-Qian Mercury Ore Zone

This paper deals with an improvement in the logical information method. The advantage degree and the information degree are introduced as the main indexes of evaluating a target, and a three-form logical information model of the southern section of he Xiang-Qian mercury ore zone is established. The correlation of the mercury ore resources with the advantage degree is discussed, and the aim of the orientating and quantitative calculation is achieved. This paper points out: The southern section of the Xiang-Qian mercury ore zone is basically revealed through many years' exploration, but there are some more potential resources. Some of the likely ore-forming areas determined in this research are on the points of the known deposits or nearby, which are expected to increase tht reserves. Some other mineral deposits are small, dispersed and deeply located, so their discovery and exploitage remain difficult in the present conditions of technology and economy. These may be regarded as final potential resources at the present indusstrial level for reference in making a long-term programme.
