| 摘 要： | 化学地层学因其交叉学科特点和研究对象的复杂性使得研究过程中任何一个环节的不足都将造成测试出现偏差,成果的可信度也将出现问题。高昂的成本也要求研究者把有限的资源集中到正确的目标上。近20年研究历程却恰恰将此类性质的问题陆续暴露了出来。如采样阶段获取原生性状考虑不充分或依据不足、测试阶段缺乏校验、数据分析阶段挖潜和综合利用有待完善以及化学岩、碎屑岩和生物岩各自的基础性和针对性研究有待提高等。有些问题带有相当程度的普遍性,有些甚至是严重的核心技术问题。笔者结合最新相关研究成果对上述问题进行了逐一分析和系统修正。

| Abstract: | Chemical stratigraphy has been playing an increasingly important part in solving stratigraphical problems.Nevertheless,its inter-discipline characteristics such as multi-step, intricate technology and high cost present critical requirements to its researchers for their comprehensive qualifications such as structure of knowledge.Deficiency of any step would bring defects or mistakes to the test result and study reliability.These problems have already been exposed one by one in chemical stratigraphy in the past twenty years.Hence the guaranteeing of original characteristics of testing samples constitutes a most important problem. The research resources could be focused to the proper targets in the process of sampling in field work and the preparation of testing samples in indoor study. With the help of cathode luminescence,the disturbance of diagenesis could be excluded and eliminated eventually.How to verify the systematic errors of testing instruments and how to make the most of these testing data are also the crucial problems which should be solved.Owing to the characteristics of carbonatite,debris and fossil shells,there are still some weak points that should be strengthened in chemical stratigraphy studies. |
