Voluminous acid volcanism in the Busheveld Complex: A

The 2.1 b.y. old Rooiberg Felsite roofs and is intruded by the mafic layered rocks and granites of the Bushveld Complex. The felsite unit, which locally exceeds 5 km in thickness and may represent an originally erupted volume of more than 300,000 km3, is dominated by rhyolitic to dacitic lavas with minor pyroclastic and sedimentary rock types.

Felsic End to Bushveld Differentiation

Abstract. The similarities in age (c. 206 Ga) and isotopic composition of the Bushveld Igneous Complex and the overlying Rooiberg Group felsic volcanic rocks suggest the possibility that the two are cogenetic.To investigate this possibility we derive a robust new estimate of the major and trace element bulk composition of the Bushveld Upper Zone and Upper Main Zone (UUMZ).
