Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Solid Earth SciencesMigmatites can record the complex melting processes during crustal anatexis, and investigating their petrogenesis is crucial for deciphering the chemical differentiation processes of continental crust.

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 ...

Interpretation of Nd, Sr and Pb isotope data from Archean migmatites in Lofoten-Vesterålen, Norway
, 1978 Sm-Nd data for the Archean granulite and amphibolite facies migmatites of Langøy and Hinnøy in Vesterålen are presented which indicate that their protoliths formed ∼2.6 AE ago.

MIGMATITES OF THE MUSKOKA DOMAIN, GRENVILLE PROVINCE, ONTARIO
, 1998 The Muskoka Domain, Central Gneiss Belt, Grenville Province, Ontario, is characterized by widespread highly migmatitic orthogneisses. The purpose of this study is to describe a variety of migmatites and associated rocks from a small section ...

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.

Chemical petrology of some pelitic gneisses and migmatites from the Thor-Odin area, British Columbia
, 1970 The Shuswap metamorphic terrain of British Columbia is marked by the occurrence of gneiss domes, one of these in the Thor-Odin area. In this case, a core of migmatites and granitoid gneisses is surrounded by a mantle of unmigmatized gneisses.
