Environmental Mineralogy [PDF]

, 2000
Abstract The writing and production of this volume recognize its potential role as a textbook for courses in “Environmental Mineralogy”, a field that calls on both core mineralogical skills and interdisciplinary understanding across chemical, biological and geological fields.

Chemical weathering and provenance evolution of Holocene–Recent sediments from the Western Indus Shelf, Northern Arabian Sea inferred from physical and mineralogical properties [PDF]

, 2012
We present a multi-proxy mineral record based on X-ray diffraction and diffuse reflectance spectrophotometry analysis for two cores from the western Indus Shelf in order to reconstruct changing weathering intensities, sediment transport, and provenance ...

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]

, 2017
Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

Jarosite versus Soluble Iron-Sulfate Formation and Their Role in Acid Mine Drainage Formation at the Pan de Azúcar Mine Tailings (Zn-Pb-Ag), NW Argentina [PDF]

, 2014
Secondary jarosite and water-soluble iron-sulfate minerals control the composition of acid mine waters formed by the oxidation of sulfide in tailings impoundments at the (Zn-Pb-Ag) Pan de Azúcar mine located in the Pozuelos Lagoon Basin (semi-arid ...

Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]

, 2017
We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...

SR-FTiR microscopy and FTIR imaging in the earth sciences

, 2013
During the last decades, several books have been devoted to the application of spectroscopic methods in mineralogy. Several short courses and meetings have addressed particular aspects of spectroscopy, such as the analysis of hydrous components in ...

Crystal-chemistry and short-range order of fluoro-edenite and fluoro-pargasite: a combined x-ray diffraction and ftir spectroscopic approach [PDF]

, 2013
In this study we address the crystal-chemistry of a set of five samples of F-rich amphiboles from the Franklin marble (USA), using a combination of microchemical (EMPA), SREF, and FTIR spectroscopy methods. The EMPA data show that three samples fall into

An ion probe study of the sulphur isotopic composition of Fe-Ni sulphides in CM carbonaceous chondrites [PDF]

, 2004
From the Introduction: The CM chondrites have endured variable degrees of aqueous alteration [1] which has changed their original mineralogy. A detailed study of the petrology and mineralogy of the sulphides in a suite of increasingly aqueously altered ...

Zircon ages in granulite facies rocks: decoupling from geochemistry above 850 °C? [PDF]

, 2018
Granulite facies rocks frequently show a large spread in their zircon ages, the interpretation of which raises questions: Has the isotopic system been disturbed? By what process(es) and conditions did the alteration occur?
