摘要: Using chemical evidence, particularly the variations between titanium and iron + magnesium, we demonstrate that petrogenetic processes operated within Central Victorian granitic host magmas their igneous microgranular enclave suites are dissimilar. Chemical series result from a variety of what might be called ‘orderly’ processes, resulting in linear or curvilinear trends variation diagrams. Those affected commonly resulted scattered, chaotic variations. Even cases where an suite displays more orderly variation, it is demonstrable hypothesis simple mixing magma magma, to bring about overall variations, cannot supported. The had vastly smaller volumes compared with magmas. Thus, they have undergone hybridisation through deep crustal melts both mechanical interactions...
