Optimizing Raman Spectral Collection for Quartz and Zircon Crystals for Elastic Geothermobarometry

, 2020
Raman microspectroscopy is widely used to identify and characterize organic and inorganic compounds. In the geosciences, Raman microspectroscopy has been used to identify mineral and fluid inclusions in host crystals, as well as to calculate pressure ...

Geothermobarometry of Cordierite-Bearing Metapelites of the Hudson Highlands, Southeastern NY

, 2014
Various P-T determinations have been reported on metasedimentary rock suites in the New Jersey and Hudson Highlands using different geothermobarometers, but all have yielded relatively large P-T ranges and none have used cordierite in a quantitative way.

Petrography, Mineral Chemistry and Geothermobarometry of Andalusite- Bearing Schists North of Azna (Northern Sanandaj-Sirjan Zone, Iran)

Journal of Economic Geology, 2016
Introduction The area studied is located north of Azna (Lorestan Province) in a small portion of the Sanandaj – Sirjan structural zone (Mohajjel et al., 2003).This area is part of the Zagros orogenic belt, formed by the opening and closure of Neotethyan

Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: Origin and evolution of the Kangâmiut mafic dyke swarm, West Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2006
The Kangâmiut dyke swarm in West Greenland intruded Archaean terrains at 2.04 Ga, and its northern portion was subsequently metamorphosed to granulite facies during the Nagssugtoqidian orogeny(c. 1.8 Ga).

Arc-related Alaskan type magmatism: evidence from pyroxenites associated with the Pakkanadu alkaline-ultramafic complex, Southern India

Frontiers in Earth Science
Petrological and major-trace element mineral chemistry studies have been carried out on pyroxenites from the Pakkanadu alkaline-ultramafic complex from the southern India to understand their origin and nature of magma responsible for ultramafic magmatism

The Wongwibinda Complex, New England fold belt: a tilted low-P high-T terrane?

, 2018
The Wongwibinda Complex is a rare exposure of deep low-pressure, high-temperature (low-P, high-T) New England Fold Belt near Armidale, NSW. The west to east thermal gradient in the Complex, which ranges from virtually unmetamorphosed sediments to ...
