Cadalso de los Vidrios leucogranite ‘Blanco Cristal’: a widely used heritage stone from Spain
Special Publications, 2019Cadalso de los Vidrios leucogranite is extracted from the Sierra de Guadarrama (Spanish Central System) under the trade name ‘Blanco Cristal’. It is a fine- to medium-grained, hypidiomorphic and equigranular building stone that has been used in many ...

The role of fluids in the formation of High Himalayan leucogranites
Geological Society, London, Special Publications, 1993Abstract During fractional melting of the crust, the availability of fluids is a critical variable that influences the melt fraction obtained, the capacity of the melt to migrate from its source and the relationship between melting and uplift.

The Formation and Age of Leucogranitic Melt in the Garhwal Himalaya
2023Metamorphism during orogenic evolution results in the melting of high-grade metamorphic rocks which dramatically decreases mechanical strength, activates shear zones, and may consequently initiate exhumation. The timescales of anatexis, melt amalgamation, migration, and emplacement are the focus of active research and have critical implications for ...

Late Vendian postcollisional leucogranites of Yenisei Ridge
Doklady Earth Sciences, 2017The Late Vendian (540–550 Ma) U–Pb zircon age of postcollisional granitoids in the Osinovka Massif was obtained for the first time. The Osinovka Massif is located in rocks of the island-arc complex of the Isakovka Terrane, in the northwestern part of the Sayany–Yenisei accretion belt. These events stand for the final stage of the Neoproterozoic history

The Isotopic Characterization of Aqueous and Leucogranitic Crustal Fluids
1989The 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 ...

Leucogranite intrusions in Eastern Kazakhstan: age, composition and mechanisms of formation
Doklady Rossijskoj akademii nauk. Nauki o ZemleThere 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.

Himalayan leucogranites and migmatites: nature, timing and duration of anatexis
Journal of Metamorphic Geology, 2016AbstractWidespread 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
