石质文物表面变质层的环境地球化学特征

ENVIRONMENTAL GEOCHEMICAL CHARACTERISTICS OF ALTERED SURFACE LAYERS OF STONY CULTURAL RELICS

用电子探针法分析石质文物表面层切片,变质层厚度、结构和组成等的差异,是由于不同的大气环境造成的。

Electron mieroprobe analysis of thin sections prepared from altered surface layers of stony cultural relics has been conducted,revealing that the differences in thickness,structure and composition of the altered surface layers are due to varying degree of atmospheric weathering.
