Mineralogy and petrography of phosphate minerals from Brazilian pegmatites, with a special emphasis on their relations with silicates

photo_projet3_resized

Abstract The family of phosphate minerals contains more than 500 mineral species, which generally occur in rare-element granitic pegmatites. The knowledge of the crystal structures of these minerals, of their stability, and of their petrographic relationships, constitutes a powerful tool to understand the pressure-temperature-oxygen fugacity conditions which prevailed in rare-elements granitic pegmatites, during the crystallisation..

Mineralogy of Luxembourg: Inventory of the minerals species and their localities

photo_projet2__resized

Abstract Only a few thinks are known about the mineralogy of Luxembourg. Very few scientific studies were published before 1996. However, the first studies bring many interesting surprises. In particular studies of the copper, lead and antimony mines of the “Oesling” have revealed extremely rare mineral species such as brandholzite, chalcostibnite or ullmannite. In the.. Lire la suite

The Rocks of the Grand-Duchy of Luxembourg: Creation of a lithotheca and microscopic analysis of the facies.

photo_projet1__resized

Abstract The first real petrographical collection of the Museum dates back to 1852, when amateur geologists decided to make a geological map of the country. Now, the existing rocks collection contains approximately 1500 samples, 350 are national samples. The idea of developing a concept called “scientific lithotheca of the rocks of Luxembourg” was born in.. Lire la suite
