The Moruya Batholith and geochemical contrasts between the Moruya and Jindabyne suites

摘要: Abstract Rocks of the Moruya Batholith range from gabbros and gabbroic diorites through quartz tonalites to granodiorites rare adamellites. The appear as small, early bodies intruded enclosed by tonalites. These gabbroids are petrographically chemically distinct granitoids. latter occur a meridionally‐oriented sequence nine separate plutons. Mafic xenoliths most abundant in tonalites; they similar their host granitoids more mafic extension variation granitoid compositions. various considered be derived source rocks, with representing modified material relict partial melting that source. Comparison chemical data those I‐types Jindabyne Suite Kosciusko Batholith, shows potassium content is indistinguis...
