摘要
洞穴是岩溶环境系统的重要组成部分,在发育过程中形成了极为丰富的洞穴堆积物。洞穴堆积物主要包括原地碎屑堆积物、异地碎屑堆积物、化学堆积物、生物堆积物以及人为堆积物,在堆积、埋藏过程中受到沉积期后作用的扰动。微形态是利用显微及超显微技术对原位定向样品进行研究的一门学科,旨在分析肉眼无法识别的成分、结构、构造特征,以及其时序、空间和成因关系。通过总结洞穴堆积物微形态研究的最新进展,重点介绍了微形态分析在恢复洞穴古气候与古环境、重建洞穴堆积物的堆积与埋藏过程、构建地层年代学框架、解译古人类活动及遗传信息等方面的应用,评估了洞穴堆积物中所蕴含的地质学与考古学价值。目前,在国内的洞穴堆积物研究中,微形态分析并未得到广泛的应用,由此展望了微形态分析的未来发展方向与广阔应用前景。
As the important part of a karst system,caves preserve numerous geological and archaeological deposits,including autochthonous,allochthonous,chemical,biological,and anthropogenic deposits,which are disturbed by the post-depositional processes in the cave deposit process.Micromorphology is the study of undisturbed,oriented samples,with the aid of microscopic and ultramicroscopic techniques,to identify the composition,texture,and structure that cannot be observed by the naked eye and deduce their chronological,spatial,and genetic relationships.Here,we reviewed the current research on micromorphological analysis of different cave deposits.The micromorphological analysis has been applied widely,including the restoration of the cave paleoclimate and paleoenvironment,the reconstruction of the cave deposit and burial process,the construction of stratigraphic chronology framework,and the interpretation of ancient human activities and genetic information.However,micromorphological analysis has not fully applied on the cave deposits in China.We are curious as to the broad application prospect of this effective research method.
