Abstract
The origination and differentiation of rare metalbearing, alkaline granites has attracted extensive interests because of their economic significance.
Highlights
The origination and differentiation of rare metalbearing, alkaline granites has attracted extensive interests because of their economic significance
The unalterated alkaline granites of the intrusion is mainly composed of orthoclase (~30 vol %), albite (~40 vol %), quartz (~15 vol %), biotite
Considering relatively low whole-rock fluorine concentrations (2187 to 8833 ppm) as well as the positively linear correlation between whole-rock CaO and F, implying that most fluorine initially incorporated in the melts were likely removed because of the separation of Ca-fluoride melt and silicate melt
Summary
The origination and differentiation of rare metalbearing, alkaline granites has attracted extensive interests because of their economic significance.
