TL;DR: In this article, the results from a second characterisation of the 91500 zircon, including data from electron probe microanalysis, laser ablation inductively coupled plasma-mass spectrometer (LA-ICP-MS), secondary ion mass spectrometry (SIMS), and laser fluorination analyses, were reported.

TL;DR: The first results from a suite of large, gem crystals which cover a broad spectrum of minerals in which light elements are major constituents using both in situ and wet chemical techniques were reported in this paper.

TL;DR: The Carajas Mineral Province in northern Brazil contains a variety of world-class (>100 Mt ore) iron oxide copper-gold (IOCG) deposits, including the only Archean examples of this deposit class (e.g., the Igarape Bahia/Alemao and Salobo deposits).

TL;DR: O tracer diffusion in Czochralski-grown mullite single crystals is investigated along [010] and [001]. Oxygen diffusion coefficients range between ∼5 × 10−20 m2/s (1250°C) and ∼9 × 10 −18 m2 /s (1525°C), the data does not show any significant anisotropic.

TL;DR: In this paper, the authors studied calcic amphiboles from an incompletely mixed magmatic rock association of mainly intermediate dioritic composition and showed that the amphibole grains consist of two different calcic hornblende varieties: (1) a Si- and Mg-rich variety and (2) a variety enriched in Al, Ti, Fe, K, and Na.
