Leucogranite from Srednja Rijeka (Moslavacka Gora, Croatia)

2007
The Mt. Moslavacka Gora represents crystalline crust exposed over an area of 180 km2 in the southwestern part of the Pannonian Basin. It consists of a S-type granitoid pluton surrounded by migmatites and metamorphic rocks of amphibolite to granulite facies grade.

The Isotopic Characterization of Aqueous and Leucogranitic Crustal Fluids

1989
The H- and O-isotope characteristics of the principal water types - sea, meteoric, formation, organic, metamorphic, magmatic and hydrothermal-are outlined. Sea and meteoric surface waters can be involved with deep crustal processes following their downward penetration, or by their upward infiltration after oceanic or continental subduction processes ...

Himalayan leucogranites and migmatites: nature, timing and duration of anatexis

Journal of Metamorphic Geology, 2016
AbstractWidespread anatexis was a regional response to the evolution of the Himalayan‐Tibetan Orogen that occurred some 30 Ma after collision between Asia and India. This paper reviews the nature, timing, duration and conditions of anatexis and leucogranite formation in the Greater Himalayan Sequence (GHS), and compares them to contemporaneous granites

Leucogranite intrusions in Eastern Kazakhstan: age, composition and mechanisms of formation

Doklady Rossijskoj akademii nauk. Nauki o Zemle
There are several large intrusions composed of 70–75% leucogranites within Eastern Kazakhstan. Information on the age of the intrusions is provided, the features of the composition of the rocks are considered, and conclusions about the petrogenetic mechanisms of forming of leucogranite magmas are drawn.

Comportement magmatique et hydrothermal de l’uranium dans les leucogranites peralumineux syntectoniques : le cas des leucogranites carbonifères fertiles en uranium du Massif Armoricain

2016
Dans la chaine hercynienne européenne, la majorité desminéralisations uranifères (filons ou épisyenites) est représentéepar des gisements hydrothermaux spatialement associés àdes leucogranites peralumineux d’âge Carbonifère. Ainsi, dans leMassif Armoricain, 20000 t d’uranium ont été extraites principalementdes trois districts uranifères associés aux ...
