摘要:In the present paper we selected some typical samples from Luodian jade to perform FUR test in order to study the vibration attribution of crystals structure. The results confirm that the main mineral composition of Luodian jade is tremolite. Not only has it been not reported in other IR study on natural nephrite that the absorption bands at wave numbers between 840 and 860 cm(-1) caused by residual diopside exist in Luodian jade with the process of tremolite rock transformed to nephrite, but is also the biggest difference between the Luodian jade and other nephrite. The results reveal important mineralogy evidence of metamorphism of Luodian jade, and on the other hand, it also shows that there is a certain difference in the process of nephrite change between Luodian jade and other natural nephrite. Moreover, it further suggests that Luodian jade is a kind of new genetic nephrite ore.
