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.

Tectonics, Volume 45, Issue 3, March 2026.Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

, 2015 Migmatites are a meta-igneous rock which crystallized early in the stages of melt, capturing the process of anatexas, or partial melting. As part of a multi-disciplinary study of rocks in the Migmatite-Granite belt of the Northern Appalachians, we have ...

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

Genesis of the migmatites of Breidvagnipa, East Antarctica
, 1998 P(論文)Various types of migmatites and peraluminous granites are widely distributed at Breidvagnipa, which is situated in the granulite-facies part of the Lutzow-Holm Complex (LHC) on the eastern coast of Lutzow-Holm Bay, East Antarctica.

Migmatite and melt segregation at Cooma, New South Wales
, 1992 The Cooma Complex of southeastern New South Wales comprises an andalusite-bearing S-type granodiorite surrounded by migmatites and low-pressure metamorphosed pelitic and psammitic sediments.

Lithosphere Destabilization by Melt Weakening and Crust-Mantle Interactions : Implications for Generation of Granite-Migmatite Belts [PDF]
, 2018 Orogenic crustal anatexis is a still poorly understood process due to the complexity of the thermal and geodynamical interaction between mantle and crustal processes during and after continental collision. Here we present a novel conceptual model for the

Residual Soils Derived from Charnockite and Migmatite as Road Pavement Layer Materials [PDF]
, 2017 Suitable soils for road pavement layer construction are getting depleted. Highway Engineers are consistently in search of locally-available and suitable soils for road construction. This paper investigates the potential use of residual soils derived from

Shear strain in the St. Malo migmatite dome (N Brittany)
, 1997 The Cadomian migmatite dome of St. Malo is affected by centimetric to metric shear bands. The shear bands bear a stretching lineation underlined by alignments of fibrous sillimanite crystals at Dinard and St. Briac outcrops.
