贵州省石炭纪早期古土壤的发现及其意义

The Discovery and Its Significance of Early Carboniferous Paleosols in Guizhou Province

古土壤蕴涵着古老时期的大气氧、二氧化碳以及生态植被的演化信息 ,利用有效的手段提取这些信息并据此推测古气候环境。在贵州省的遵义苟江、道真县、正安县等地发现了保存完好的石炭纪早期的古土壤剖面 ,为恢复该地质时期云贵高原的大气氧演化、二氧化碳浓度与生态植被提供了天然的现场条件。

Paleosols (fossil soil) contained lots of the evolution information over geologic time scales, such as past oxygen, carbon dioxide, ecological plant. Paleo environmental information could be speculated by using effective methods. The paleosols sections found in Goujiang of Zunyi county, Zhenan county and Daozheng county in Guizhou province provided condition to recover the past air oxygen, carbon dioxide, ecological plant in Early Carboniferous.
