| 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. There are two morphological (zircon) types recognized in this sample. Type 1 zircons show a well-developed prism and pyramids. They belong to subtypes S16-S17 and/or S21-S22 of Pupin's (1980) typological classification. Such morphological forms are common in zircon from tonalites. Type 2 zircons from the Kosciusko tonalite have a well-developed prism and pyramids. They correspond to subtypes L2-L3 and/or S2-S3 and/or S7-S8. This morphological type is more typical of zircon from aluminous monzogranites and granodiorites." |
