解读《地学元素和离子周期表》

本文对最近出版、颇受国外学界关注的《地学元素和离子周期表》作了介绍。内容涉及其与传统周期表相比的优点、新的理论基础、构成、其中元素和离子的分类、揭示的地球化学型式与趋势、应用实例、存在的问题、及其对科研与地学教学的意义,即(1)它有助于启迪研究出其他学科的《元素和离子周期表;》(2)它本身将随化学等基础学科与测试手段的发展而进阶,从而解释更多的例外;(3)它是地球化学整体论的成果,是对地球化学、海洋化学、营养化学中的自然组合和趋势的综合,给地球化学普遍型式与趋势一种更清澈的多维标度下的透视。所以它对地球化学总体及更低层次分学科的研究都有指导意义,必将成为地质学的必修内容和地球化学的入门工具。它也是作为挂图模式的纲要视图的杰出案例。

Understanding An Earth Scientist''''s Periodic Table of the Elements and Their Ions

This paper introduces the recently published,overseas academically attention-getting production An Earth Scientist's Periodic Table of the Elements and Their Ions.It covers the table's advantages over the conventional analogs,the new theoretical bases,the makeup,the classification of elements and ions therein,the indicated geochemical patterns and trends,the cases exemplifying them,the existing problems and the significance for scientific research and geoscience education: it helps to instruct scientists to develop analogs in other fields;it itself will be upgraded with the developments of both basic theories in chemistry and geochemical testing instruments;it is a geochemical holistic product synthesizing natural groupings and trends in geochemistry,marine chemistry and nutrient chemistry,and rendering general geochemical patterns and trends a clearer multiscale perspective.Thus it is significant for the researches in the overall and subordinate levels of geochemistry,and will definitely become a requirement for geology majors and an introductory tool for studying geochemistry,and as a model for poster presentations it is an outstanding example of synoptic design.
