洛塔岩溶山区的第四纪堆积物分布虽不普遍,但由于它作为第四纪沉积环境中所形成的产物,包含着本身形成条件和环境的信息,因此分析第四纪堆积物的地球化学特征,研究其元素迁移和富集的规律,有助于进一步阐明该区第四纪古气候、古环境的变迁;同时也是研究岩溶发育规律和发育历史的重要资料。本文就有关资料对洛塔岩溶山区第四纪以来地球化学环境特征作某些探讨。 一、自然地理条件
Quaternary sediments in Lota karst area are not widespread, but because of their formation as a product of Quaternary sedimentary environment, they contain information about their formation conditions and environment. Therefore, geochemistry of Quaternary deposits Characteristics and study of the rules of its elements migration and enrichment will help to further clarify the Quaternary paleoclimate and paleoenvironment changes in the area; it is also an important data for studying the law of karst development and development history. This paper makes some discussions on the geochemical environment characteristics of Quaternary in Lota karst area based on relevant data. First, the natural and geographical conditions
