Temperature effects on rock engineering properties and rock-fluid chemistry in opal-CT-bearing chalk
(Elsevier Science, 2018-10)
In this study, eight tri-axial tests on Cretaceous age outcrop chalk from Aalborg have been performed systematically by injecting MgCl2 for the first time at different temperatures (25, 60, 92, 110 and 130 °C) and for ...
Topaz magmatic crystallization in rhyolites of the Central Andes (Chivinar volcanic complex, NW Argentina): Constraints from texture, mineralogy and rock chemistry
(Elsevier Science, 2013-10)
Topaz-bearing rhyolite lavas were erupted as domes and cryptodomes during the early history of the Late Miocene Chivinar volcano, in Central Andes. These are the only topaz rhyolite lavas recognized in Central Andes. ...

Técnicas de análises de densidade e porosidade de minério de ferro por cálculo normativo mineralógico, microtomografia computadorizada, permoporosimetria e picnometria clássica : um estudo comparativo entre os métodos
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2019-11-21)
During the mineral resources estimation process the apparent density of the rock material is of great relevance because it is a multiplier factor of the modeled volumes. Mistakes caused by low numbers of samples, low ...
Application of the mineralogy and mineral chemistry of carbonates as a genetic tool in the hydrothermal environment
(MDPI, 2021)
The mineralogy and mineral chemistry of carbonates from various hydrothermal deposits, including volcanic-hosted Au-Cu epithermal, "Chilean Manto-type" Cu(-Ag), stratabound Mn, and Ag-Ba vein deposits from Spain and Chile, ...

Experiment and quantification of weight: Late-renaissance and early modern medical, mineralogical and chemical discussions on the weights of metals
(Brill Academic Publishers, 2020-11-17)
This paper explores how a set of observations on the weight of lead were interpreted and assessed between the 1540s and the 1630s across three different interconnecting disciplines: medicine, mineralogy and chemistry. The ...
Deciphering the weathering processes using environmental mineralogy and geochemistry: Towards an integrated model of laterite and podzol genesis in the Upper Amazon Basin
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2011)
This article reports major results from collaborative research between France and Brazil on soil and water systems, carried out in the Upper Amazon Basin. It reveals the weathering processes acting in the partly inundated, ...
