Southern granulite terrain, south of the Palghat-Cauvery shear zone: Implications for India-Madagascar connection

, 1999
The present paper correlates the southern Madgascar terrain, south of the Ranotsara shear with the granulite terrain of southern India, occurring south of the Palghat-Cauvery (P-C) shear zone.

Degradation of granulite and charnockite aggregates under simulated train loading: Morphological and mechanical insights for railway ballast

Journal of Materials Research and Technology
The performance of railway ballast strongly depends on the mineralogical and morphological characteristics of the aggregates. However, little is known about the behavior of regional rocks in Rio de Janeiro, Brazil, under manipulation caused by railway ...

Are Estimates of Lower Continental Crust Bulk Composition Biased Due to Seismic Anisotropy?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Most seismic inferences on the bulk composition of the lower continental crust are based on P‐wave velocities inferred from seismic wide‐angle data, for which the direction of propagation in the target region is sub‐horizontal. Given the likely presence of anisotropy in many parts of the lower continental crust, these estimates could be biased

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Granulite-hosted gold: Tectonic setting and lithogeochemistry of the Tropicana deposit, Western Australia

, 2016
The Tropicana gold deposit (7.9 Moz) is hosted by the Neoarchean, amphibolite-to granulite-grade Tropicana Gneiss. These rocks form part of the Plumridge terrane, a tectonic unit that separates the in situ eastern margin of the Yilgarn craton from ...

FT-IR spectroscopic investigation of hydrous components in sillimanite from Eastern Ghat Granulite Belt, India

, 1999
FT-IR spectra of sillimanite samples from high grade regionally metamorphosed rocks belonging to the granulite terrain (amphibolite to pyroxene granulite facies) deciphers prominent OH features.

An Analysis of an Appalachian Metamorphic Suite

, 2011
The Blue Ridge is one of over a dozen provinces located in the much larger Appalachian Mountain Range which spans across the eastern United States. The Appalachian Mountains began to form close to 500 million years ago and rocks within the Blue Ridge ...

Origin of the granulite enclaves in Indo-Sinian peraluminous granites, South China and its implication for crustal anatexis

, 2012
Metasedimentary granulite enclaves hosted in the Indo-Sinian Darongshan-Shiwandashan granite belt from the southeastern Guangxi province, South China, experienced a three-stage metamorphic evolution: (1) the early prograde metamorphism in the stability ...
