Meiling jade belongs to tremolite jade series, which can be classified as white jade, grey-white jade, and grey jade. The mineralogical and metallogenic features of Meiling jade have been studied on the bases of field work, microscopic observation , chemical and spectrum analyses. The results show that the mineral compositions of white jade and grey jade are mainly tremolite and Na-enriched tremolite respectively. It can be deduced that white jade was formed under the condition of contact metasomatism, whereas grey jade was the injected mass of “jade liquid” under the condition of low pressure and high temperature, formed later than white jade.
