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.

Yankuang ceshi, 2014 Accompanied by the crucial breakthrough of prospecting for skarn-type Cu-W deposit in Zhuxi of Jiangxi Province, the previously established model of ore distribution was incorrect in that the W and Cu deposits distribution was in the south and north ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).

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.

Lamprophyric rock locations in Greece [PDF]
Mineralogia, 2019 Abstract Twenty-four areas with lamprophyric formations have been located through a bibliographic search in Macedonia, Thrace, the islands and Attica. Most lamprophyre types have been identified including rare “alkali minette”. In most localities the dikes/sills appear to be late mantle products associated with deep faulting following

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract One of the main limitations in simulating subsolidus metasomatism is the decoupling between thermomechanical models and chemical/thermodynamic modeling. This decoupling amplifies the uncertainty associated with mass transport. Here, we introduce a fluid‐rock chemical‐thermomechanical interaction scheme, which integrates thermodynamic modeling (

Ages of Lamprophyre Dikes and of the Mongowin Pluton, North Shore of Lake Huron, Ontario, Canada
, 1971 Rb–Sr analyses have been carried out on samples of lamprophyre dikes and of granophyric phases of the Mongowin Pluton, two units that intrude Huronian metasediments in the Espanola–Massey area.
