成矿的

In this paper, the study of metallogenic system and its evolution is summarized into several main points as follows.

中文摘要：成矿系统研究体现了系统观和历史观的结合，是现代矿床学的一个发展趋势。

Because metallogenic systems are largely self-organized, they have spontaneously ordered structure in space, time and process.

由于成矿系统在很大程度上是自组织的、具有自发产生空间上、时间上或作用上的有序结构。
