摘要
地球化学特征是硅质结核形成过程中,主微量元素和稀土元素的迁移的表征。通过对地球化学元素的研究,可反推出硅质结核形成环境和地质背景,了解当时的气候、温度等环境元素。
Geochemical characteristics are the characterization of the migration of main and trace elements and rare earth elements during the formation of siliceous nodules.Through the study of geochemical elements,can reverse deduce the formation environment and geological background of siliceous nodules,and understand the climate,temperature and other environmental elements at that time.
