Crystallization processes in migmatites
American Mineralogist, 2001 An important prerequisite for interpreting microstructures in plutonic and metamorphic rocks is understanding crystallization processes. This study uses crystal size distribution (CSD) and grain shape parameters to investigate mineral-reaction-controlled crystal growth and melt solidification in migmatites of the Bayerische Wald (Variscan Orogeny ...

Petrogenesis of migmatites and leucogranites from Sierra de Molinos, Salta, Northwest Argentina: A petrologic and geochemical study [PDF]
Lithos, 2013 In Sierra de Molinos, Eastern Cordillera, NW Argentina the relationship between different components of an anatectic system developed in high temperature and low pressure conditions (800 °C and 4_6 kbar) can be observed. This allows the direct insight on

What can we learn from melt inclusions in migmatites and granulites? [PDF]
Lithos, 2015 With less than two decades of activity, research on melt inclusions (MI) in crystals from rocks that have undergone crustal anatexis – migmatites and granulites – is a recent addition to crustal petrology and geochemistry.

Journal of Geophysical Research: Solid EarthInternational audienceAbstract The coupling of magnetic fabrics and magnetic remanences is critical in interpreting paleomagnetic data. To estimate whether primary magnetic fabrics imply primary magnetic remanences, and to assess the practicability of ...

Mesoarchean migmatites of the Carajás Province: From intra-arc melting to collision
Lithos, 2021 In the Carajás Domain, northern Carajás Province, Amazonian Craton, the oldest units encompass the Mesoarchean migmatites of the Xicrim-Cateté Orthogranulite and Xingu Complex. The Xicrim-Cateté Orthogranulite underwent early dehydration and late water-

The composition of nanogranitoids in migmatites overlying the Ronda peridotites (Betic Cordillera, S Spain): the anatectic history of a polymetamorphic basement [PDF]
Contributions To Mineralogy and Petrology, 2016 International audienceThe study of the composition of primary melts during anatexis of high-pressure granulitic migmatites is relevant to understand the generation and differentiation of continental crust.

Analysis of Variance of the Composition of a Migmatite
Science, 1963To determine the variation of composition in a Front Range migmatite, an analysis of variance (nested design) was run on field measurements. The regional variation is too small to be considered significant, but the areal variation (between outcrops) is large enough to warrant comparison with some other measurable variable such as country rock ...
