Prograde zircon growth in migmatites

Journal of Metamorphic Geology, 2023
AbstractEmpirical studies of zircon in migmatites document features compatible with growth during heating at suprasolidus conditions. However, numerical modelling of zircon behaviour suggests that suprasolidus zircon is expected to grow only during cooling and melt crystallization.

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

Migmatites, Melting, and Metamorphism

Eos, Transactions American Geophysical Union, 1985
This is a praiseworthy collection of papers that illustrates the great range of interests necessary to understand migmatite genesis. The strength of the collection lies in its broad approach to the study of migmatites and its emphasis on the link between “igneous” and “metamorphic” processes.

Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

Archaeological Prospection, Volume 33, Issue 2, Page 499-517, April/June 2026.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

Neoproterozoic magmatic accretion and Pan-African reworking-differentiation of mafic crust derived from an enriched mantle: evidences from structural analysis, petrology and geochemistry of the Ketté gold district (Eastern Cameroon)

BSGF - Earth Sciences Bulletin
The gold-rich Ketté formations belong to the Adamawa-Yadé block of the Neoproterozoic Central Africa Orogenic Belt. They consist of a complex association of tonalite, granodiorite, and heterogeneous granite including rafts of metapyroxenite, amphibolite,

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

Journal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

Geology of the Montigiu Nieddu metamorphic basement, NE Sardinia (Italy)

Journal of Maps, 2020
A geological map at 1:10,000 scale is presented that shows the distribution of the metamorphic rock units in the area of Montigiu (Mt.) Nieddu (NE Sardinia). These units belong to the High-Grade Metamorphic Complex in the Inner Zone of the Variscan chain

METALLOGENY OF SOUTH TISIA - MOSLAVAČKA MT., PSUNJ, PAPUK AND KRNDIJA

Rudarsko-geološko-naftni Zbornik, 2013
Core of the Moslavačka Mt. is built of S-type granite and granodiorite, wrapped up in migmatites. Outer zone is represented with metamorphites of amphibolite facies. The Moslavačka Mt.

Sorption–desorption behavior of lateritic soils at low heavy metal concentrations

Next Materials
The increasing solid waste production and leachate-related contamination risks demand effective containment strategies, particularly in tropical regions where lateritic soils are widely considered for landfill liner applications.
