湖泊碳酸盐在过去环境变化研究中的应用

Applications of Lacustrine Carbonate in Paleoenvironment Research

国内外的研究成果表明,湖泊沉积碳酸盐矿物及其微量元素、同位素分布特征记录了全球或区域古气候环境演变历史,可以从中提取大量定量化的古气候参数。因此,可以根据湖泊碳酸盐矿物的含量和碳、氧同位素变化等信息推知其形成时期的气候环境,重建古环境,揭示气候环境演变的规律。湖泊碳酸盐是一种研究古环境演化重要的代用指标,在过去气候环境变化研究中有广阔的应用前景。

Investigations revealed that the distribution of carbonates in lake sediments as well as trace elements and isotopes predominantly record the evolution of global or regional environments, from which many paleoenvimnmental parameters, such as paleotemperature, paleoprecipitation, paleosalinity, paleozoology, and paleoproductivity can be extracted. According to the contents and C,O isotopes of carbonate rocks, the rules of paleoclimate evolution can be inferred and the paleoenvimnment can be reconstructed. Lacustrine carbonate will have a vast application prospect in the future study on paleoenvimnment evolution.
