论风化壳相、古风化壳相矿床

DISCUSSIONS ON THE MODERN AND ANCIENT WEATHERING CRUST DEPOSITS

摘要: 现代风化作用形成的风化壳相矿床和更新世以前古风化作用形成的古风化壳相矿床,既不同于一般陆相沉积,如河流相、湖沼相沉积,也不同于一般海相沉积。它们有大同小异的形成机制和物质组成,后者包括风化壳物质的结构、构造,如碎屑、砾块,豆鲕、结核(结石)及矿物组成。

Abstract: It is suggested that both the weathering crust deposits resulted from modern weathering processes and the ancient weathering crust deposits resulted from pre-Pleistocene weathering processes differ from the general continental sediments and common marine sediments, respectively. They are well worth discussing as a kind of characteristic rock facies.
