Land Degradation &Development, Volume 37, Issue 9, Page 4230-4250, 30 May 2026.ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Microfossils in metasediments from Prins Karls Forland, western Svalbard [PDF]
, 1988 The stratigraphic importance of fossils is never more apparent than in attempts to unravel the complexities of metamorphic terrains. The age and stratigraphic relationships of the thick metasedimentary and metavolcanic succession of Prins Karls Forland ...

Correlation of radiometric ages of Nipissing diabase and Huronian metasediments with Proterozoic orogenic events in Ontario [PDF]
, 1969 Field evidence shows that the Huronian section of metasediments in Ontario is younger than the Archean and older than the Nipissing diabase. Previous radiometric investigations show the age of the latest Archean granitic intrusions to be about 2500 m.y.

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

Basin Research, Volume 38, Issue 3, May–June 2026.The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

The geologic potentials of Riau Islands Province and its development design
Jurnal Perspektif Pembiayaan dan Pembangunan Daerah, 2018 Geologically Riau Islands is located in the topography of the old stadium erosion. The morphology is characterized by smooth hills with convex slopes and alluvial plain consisting of the erosion products. The morphology exhibits the remnants of peneplain

Dehydroxylation of Minerals of Gadisunkapur Area with Special Reference to FTIR and Thermal Study
International Journal of Economic and Environment Geology, 2020 This paper attempts to explain the presence of OH group for micas along with some sulfate, chlorite, quartz and feldspar minerals. These minerals are found to be associated with barite vein, metasediments (quartz-chlorite schist ...
