| 摘 要： | 姚家岭锌金多金属矿床是近年来在长江中下游成矿带铜陵矿集区新发现的大型多金属矿床。姚家岭锌金多金属矿床的成矿作用具有多阶段性的特点,矿床范围内围岩蚀变强烈,蚀变类型复杂多样。三维地质信息技术及三维空间分析方法为定量化分析围岩蚀变的空间分布以及与矿化之间的相关关系提供了有利工具。本文基于上述方法,有效地对姚家岭锌金多金属矿床的围岩蚀变的分带性及其与不同矿化之间的关联性行了定量分析。较之于传统研究方法,不仅能快速地对蚀变与矿化的分布特征进行分析,还能从定量的角度获取不同信息之间的规律性和相关性。本文采用的相关方法不但有助于更准确的判定蚀变分带及规律,还可为矿床的成矿模式及找矿模型的建立提供定量化的数据支持。

| Abstract: | Yaojialing zinc-gold polymetallic deposit is a newly discovered large zinc-gold deposit in Tongling ore district, the Middle-Lower Reaches of Yangtze River metallogenic belt in recent years. Because of the multi-phase mineralization in Yaojialing zinc-gold polymetallic deposit, the alteration is strongly and complicated. Three dimensional geological information technology and spatial analysis methods provide a suit of very useful tools for quantitative analysis of spatial distribution of alteration and their relationship with mineralization. Based on them, this paper quantitatively analyses the characteristics of alteration zones and their relationship with mineralization in Yaojialing zinc-gold polymetallic deposit. Compared with common methods, the distribution pattern of alteration and mineralization can be analyzed very quickly, and meanwhile, the regularity and correlation between different information can also be acquired quantitatively. These methods can not only help to identify the alteration zone and regularity more clearly, but also can provide quantitative data for metallogenic model and exploration model established. |
