摘要

A preliminary study on the micro-structure of a special sericite-jade material has been carried out by using the XRD and SEM methods. By XRD analysis, the 2M_1 type sericite is identified as the main mineral composition of the white-colored, yellow-colored and green-colored jade. Quartz, as the secondary mineral, is also common in the green-colored jade. However, the dominant mineral composition of the black-colored jade is chlorite. SEM analysis reveals both the micro-morphology of the jade-forming minerals and the micro-structure of the mineral aggregates are various, which have significant relationships with the Guangning jade quality. Minuscular mineral grains and compact micro-structure make jade materials exquisite. Conversely, large mineral grains and the loose micro-structure make jade materials more rougher.
