摘要/Abstract

摘要： 本文试图以数学推演和计算机图形显示相结合的手段，对安徽沙溪斑岩型铜矿床多年来勘探成果的数据进行合理的归纳分组，应用趋势分析方法揭示了沙溪斑岩型铜矿体的空间形态在不同构造部位的变化特征。结合全区的地质构造、矿化蚀变特点探讨了矿体空间分布与控矿构造以及矿化蚀变之间的对应关系。研究结果表明；应用趋势分析和计算机成图技术求得的矿体空间分布与矿区勘探揭露的结果有着较一致的对应性。

Abstract: This paper presents the morphological feature of the ore bodies in Shaxi porphyry copper deposit by means of trend analysis and with the help of computer program. Considering the geological structures and the thermal fluid alteration which control the ore bodies, the authors dicuss the relationship between the distribution of ore bodies and the ore-controlling structures and thermal fluid alteration in the ore deposit. The results show that there exists good correlation between the ore bodies derived from the trend surface analysis and those from exploration.
