Modelling the combination of birefringence retardations from strain envelopes around multiple inclusions in diamond

Autor: L. M. Barron, Terrence P. Mernagh, B. J. Barron

Publikováno v: Australian Journal of Earth Sciences. 64:557-564

A paleo-alluvial 0.21 ct yellow diamond (L058) from Bingara (NSW) has three inclusions of coesite (two subequant crystals and one thin plate), each under more than 3.1 GPa internal pressure as measured by Raman spectroscopy. These inclusions cause ov

Re-appraisal of published nitrogen aggregation results in diamonds from Copeton, New South Wales

Autor: F L Sutherland, B. J. Barron, L. M. Barron

The Copeton and Bingara areas (near Inverell in the New England region, NSW, Australia) produced about 2 million diamonds from alluvial deposits mostly buried by Cenozoic basalt flows (MacNevin, 19...

Spectroscopic research on ultrahigh pressure (UHP) macrodiamond at Copeton and Bingara NSW, Eastern Australia

Autor: Terrence P. Mernagh, L. Barron, Ross E. Pogson, B. J. Barron

Publikováno v: Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy. 80:112-118

Millions of macrodiamonds were mined from Cenozoic placers across Eastern Australia, 98% from within the Copeton and Bingara area (85 km across) in the Phanerozoic New England region of New South Wales (NSW). Raman spectroscopy of inclusions in uncut

Ultrahigh pressure macro diamonds from Copeton (New South Wales, Australia), based on Raman spectroscopy of inclusions

Autor: W.D. Birch, Terrence P. Mernagh, B. J. Barron, L.M. Barron

Publikováno v: Ore Geology Reviews. 34:76-86

Mining of Cenozoic alluvial deposits at Copeton and Bingara (Eastern Australia) has produced two million macrodiamonds (0.25 ct median size). Raman spectroscopy is used to identify included minerals within uncut Copeton diamonds, with sealed chamber

Using strain birefringence in diamond to estimate the remnant pressure on an inclusion

Autor: L. M. Barron, Terrence P. Mernagh, B. J. Barron

Publikováno v: Australian Journal of Earth Sciences. 55:159-165

Raman spectroscopy is used to identify minerals in isolated sealed inclusion chambers in some New South Wales (Australia) diamonds and to determine the remnant internal pressure on each inclusion with values of each: 3.03, 3.31 and 3.54 – 3.62 GPa

Unusual pegmatoid crystallisations in a nephelinite plug, near Round Lagoon, eastern Central Plateau, Tasmania

Autor: John L. Everard, SM Forsyth, F L Sutherland, JD Hollis, Ross E. Pogson, B. J. Barron

Publikováno v: Papers and Proceedings of the Royal Society of Tasmania. :23-38

Pegmatoids in a Late Oligocene olivine nephelinite plug near Round Lagoon form a complex low-pressure fractionation suite. The host nephelinite contains meta-peridotite and meta-wehrlite mantle xenoliths and its composition (Mg# 0.63) may reflect bot

Formation conditions of Copeton (NSW) diamonds based on laser Raman spectroscopy of inclusions

Autor: Lawrence M. Barron, Terrence P. Mernagh, B. J. Barron

Publikováno v: ASEG Extended Abstracts. 2006:1-5

Laser Raman spectroscopy is used to identify mineral inclusions in situ within six Copeton diamonds and to determine the remnant internal pressure on them, namely 31-34 kbar for coesite, 13.6 and 23 kbar for diopsidic omphacite, and 8 kbar for grossu

Al-rich diopside in alluvial ruby and corundum-bearing xenoliths, Australian and SE Asian basalt fields

Autor: F L Sutherland, D A Schwarz, Gayle B Webb, R.R Coenraads, B. J. Barron, L. R. Raynor

Publikováno v: Mineralogical Magazine. 67:717-732

Alluvial rubies and sapphires are found in palaeodrainage deposits along the Cudgegong-Macquarie River system, central eastern New South Wales, Australia. A pink to red suite contains Cr (up to 0.6 wt.% Cr2O3) as the main chromophore, exceeding Fe (u
