地球化学填图与地球化学块体的谱系分析——编号系统及谱系树图的自动绘制

中国的地球化学填图研究工作起步较早并发展成为在国际上具有明显优势的学科。在此基础上提出的地球化学块体理论通过一定的编号系统绘制谱系树图来追索某元素在块体内部逐步浓集成矿的轨迹。通过谱系树图可以发现不同级别的子块体之间的亲缘关系,研究它们在时间和空间上的分布规律,结合已发现矿床的信息,预测潜在矿床的分布及其储量,从而指导找矿工作。提出了一种全新的谱系编号系统并编制了在计算机上自动绘制谱系树图的软件,同时实现了与原有编号系统的一致,解决了长期以来谱系树图不能自动绘制的问题,为地球化学块体的研究提供了一个很好的工具。

Geochemical mapping and structure of geochemical blocks-Coding system and family tree diagram computer drawing

China's geochemical mapping has maintained its leading position in the world for decades,thus stimulating the development of the concept and methodology of geochemical blocks.The geochemical family tree diagram drawn based on the concept of geochemical blocks and using a certain coding system is a powerful tool for studying the internal structure of geochemical blocks and tracing the progressive concentration of a particular metallic element to form ore deposits.Through the family tree diagram we can find the affinity between blocks of different orders and study their temporal-spatial distribution patterns,and,by using the family tree diagram,combined the information of ore deposits that have been found,we can prediction the distribution and reserves of the potential deposits and thus can guide mineral exploration.The coding and construction of the family tree diagram have been conducted manually in the past.It is a very tedious work.In this paper,the authors have developed a new family tree coding system and a software for automatic coding and construction of the family tree diagram,thus solving the long-standing problem that the family tree diagram cannot be drawn automatically.
