| sample_remark | Belousova et al 2006 paraphrased: "The Berridale Adamellite and Kosciusko Tonalite belong to the 700 km wide Paleozoic Lachlan Fold Belt (LFB) of Eastern Australia, which is characterized by a ubiquitous Ordovician flysch cut by granitoids of different geochemical character. Chappell & White (1974, 1992) introduced the terms ‘S’ and ‘I’, which was a major contribution to granite classification at the time. They considered that the composition of granites reflects their source regions and showed that there are two contrasting granitoid types in the Kosciusko and Berridale Batholiths: the S-types derived from the partial melting of metasedimentary rocks, and the I-types from igneous sources that had not been through surface weathering processes. Zircon grains from the Berridale adamellite form four distinct morphological types. Type 1 is typical of zircon populations formed in sub-alkaline and alkaline series granitoids of crustal-plus-mantle or mainly mantle origin, according to the genetic classification. They have a well-developed prism and pyramid forms (Pupin 1980 subtypes G1 and P1). Type 2 zircons show a predominance of prism forms and the presence of two pyramids, one weakly developed and the other well developed (Pupin 1980 subtypes S14 and S19). This morphological type, according to Pupin's scale, is characteristic of calc-alkaline granodiorites of hybrid (crustal and mantle) origin." |
