摘要

    

///Beryl occurred in mineral association of granite greisened muscovite, albite, beryl and quartz. Goniometry indicated that the single form crystal face growth is in turn c{0001}, s{112-1}, p{101-1}, m{101-0} and v{213-1}, the next place is n{459-4} and a{112-0}. The fluid inclusion temperatures tested by homogenous method and ingredient analysis by laser Raman spectroscope(LRS) all revealed that the tabular beryl has grown in medium-high temperature(about 303 )and stabling thermodynamics, the gas and the liquid inclusion mainly composed by H2O, CO2 and micro CH4, N2. CO2 and micro CH4, N2 possible concerns to the carbonate wallrock.
