锡铁山铅锌矿床氧化带是在典型干旱气候条件下生成的。对应于不同类型的原生矿体有硫化物型、氧化物型、浸染型等不同类型的氧化带,它们有不同的矿物共生组合,在空间分布上有明显的水平分带和垂直分带。在各类氧化带中,按照共生矿物间生成时代的相互关系及生成环境又可划分出多个亚带。运用有序地质量的最优分割法不仅可以对氧化带的划分定量化,而且揭示了氧化带形成过程的内在规律性。本文还将干旱气候条件下的氧化带与温湿地区氧化带的分带性作了系统对比。
The oxidation zone of the Xieshan lead-zinc deposit is formed under typical arid climate conditions. Corresponding to different types of primary ore bodies, there are different types of oxidized belts such as sulphide type, oxide type and dipping type. They have different mineral assemblages and have obvious horizontal and vertical zonation in spatial distribution. In various types of oxidation zone, according to the intergrowth of intergrowth mineral generation era and the formation of the environment can be divided into multiple sub-zones. Using the optimal segmentation method of ordered geology not only quantifies the division of the oxidation zone, but also reveals the inherent regularity of the formation of the oxidation zone. In this paper, we also systematically compare the zonation of oxidation zone in arid climatic conditions with the oxidation zone in warm and humid areas.
