Are A-type granites the high-temperature felsic granites? Evidence from fractionated granites of the Wangrah Suite
King, I; Chappell, Bruce; Allen, Charlotte M; White, A
A-type granites are a minor, but distinctive, component of the granites of the Lachlan Fold Belt of southeastern Australia. They are felsic rocks with SiO2 contents ranging from 69.7 to 77.1%, with an average of 73.8% (55 analyses). When unfractionated, as evidenced by high Ba contents, they are distinguished from felsic l-type granites by a greater abundance of high-field-strength elements, such as Zr. The Wangrah Suite contains a diverse association of A-type granites, comprising four main...[Show more]
