Abstract The Rhodope crystalline massif is an Alpine metamorphic complex exposed across several mountain ranges in southern Bulgaria and northern Greece which has experienced a history including continental collision, partial subduction syn-metamorphic nappe stacking followed by syn- to post-contractional extension. We present new 40 Ar/ 39 Ar fission-track data from samples taken both sides of...

This study was carried out at Federal Polytechnic; Ado Ekiti in state on geochemical appraisal of three different genetically derived lateritic soils from south western Nigeria and their respective engineering performance 2019. Twelve (12) disturbed soil samples were collected granite (GDS), gneiss (GNS) migmatite (MGS) rock terrains. These four horizons 0.5m intervals, resulting into a maximum...

Abstract Water resources in the West African Sudan Savannah are concentrated fractured crystalline and sedimentary rock aquifers. Due to their low storage, these aquifers vulnerable changes climate. This study assesses future temperature precipitation trends Koumfab watershed of northern Togo. The impact climate on surface water two types is also investigated. A fully integrated hydrologic mode...

Abstract Geological investigations of a part the crystalline basement in Baltic Sea have been performed on drill core collected from depth 1092–1093 m beneath Phanerozoic sedimentary cover offshore Latvian/Lithuanian border. The sample was analyzed for geochemistry and dated with SIMS U–Pb zircon method. Inherited cores this migmatized granodioritic orthogneiss an age 1854 ± 15 Ma. Its chemical...

The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure a continent–continent collision zone. To test established exhumation models, we synthesize geochronology and structures major basement windows provide new ages from poorly dated areas. Migmatite U–Pb zircon samples date melt crystallization at c. 405 Ma in Øygarden Comp...

The method of spectral analysis was applied to the total aeromagnetic intensity data covering district Ibapara, located on Nigeria Basement Complex in Oyo State, SW Nigeria. Prior analysis, inclined magnetisation converted vertical, reduced pole and filtered out order more correctly reflect spatial location morphology magnetic sources over geological bodies, enhance effects shallower deeper one...

The higher rate of slope erosion in the Himalayan basins is contributing to rapid change landform mountainous terrain, which has caused sedimentation, and inundation downstream. Tamakoshi basin a trans-boundary river that originates from Tibet flows through Dolakha Ramechap districts before joining Sapta Koshi river. Few studies exist Nepal attempting quantify susceptibility. However, they are ...
