TITANITE OF THE VISHNEVOGORSKY ALKALINE COMPLEX (South Ural) [PDF]

Минералогия, 2019
Titanite CaTi(SiO4 )O is a common accessory mineral of alkaline rocks and pegmatites of the Vishnevogorsky alkaline complex, South Urals. It occurs in many magmatic assemblages, is found in some metasomatites, underwent deformation and recrystallization.

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

OIB‐Type Garnet Amphibolites From the Xuerongzangbu Area, Central Lhasa Terrane, Tibet: Implications for Songduo Paleo‐Tethys Ocean Evolution and Permian Mantle Activity Along North Gondwana

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Whether the Songduo metamorphic belt represents an in situ Paleo‐Tethyan suture within the Lhasa Terrane or far‐traveled allochthonous high‐pressure slices, and how Permian mantle activity along the North Gondwana margin relates to subsequent Tethyan evolution, remain central questions in Tibetan tectonics.

Concurrent sinter-crystallization and microwave dielectric characterization of CaO-MgO-TiO2-SiO2 glass-ceramics

Journal of Asian Ceramic Societies, 2020
The present work aims to clarify sinter-crystallization behavior and microwave dielectric features of CaO-MgO-TiO2-SiO2 glass-ceramics fabricated via one-step sintering procedure at 800–950°C for 4 h. In this regard, starting glasses were obtained from a

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

MINERALOGICAL-PETROGRAPHIC FEATURES OF SYENITIC MIGMATITES OF THE ILMENOGORSKY MIASKITE BLOCK (SOUTH URALS) [PDF]

Минералогия, 2019
Syenitic migmatites of the contact of the Ilmenogorsky miaskite block are characterized by high (>500 ppm) contents of REEs, which are mainly hosted in fluorapatite and titanite of the leucosome.

Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

Probing the Elastic Anisotropy of Schistose Rocks West of the Tauern Window (Eastern Alps, Austria): The Largest Homogeneous Volume

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The anatomy of orogens is difficult to decipher as structural information is usually limited to surface and seismic data. Seismic properties are directionally dependent on anisotropic minerals, especially phyllosilicates. Due to tectonic complexity, the effect of anisotropy in seismic data is difficult to determine.
