Field excursion guide to the Geology of Fruška Gora (Southern Pannonian Basin, Serbia) [PDF]

Geološki Anali Balkanskoga Poluostrva
Fruška Gora, a prominent inselberg within the southern margin of the Pannonian Basin, preserves a complex geological record of both orogenic and post‐orogenic processes in the central Balkans.

General features of the Paleogene orogenic magmatism in Bulgaria

Geologica Balcanica, 1989
This paper is a review of the available data on the Paleogene magmatism in Bulgaria. On the Balkan Peninsula its products (mainly volcanics) form the arcuate Maccdonian-Rhodope-North Aegean volcanic zone (MRNAVZ). The Bulgarian section has been divided into volcanic areas (Struma – SVA, Central Rhodope – CRVA and East Rhodope –ERVA) which have been ...

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

Geological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Re-Evaluating A-Type Granite Petrogenesis: Formation during Ocean Opening [PDF]

Lithosphere
A-type granites are commonly emplaced in extensional settings, including post-collisional, intraplate, and back-arc environments. This study delves into the early Permian A-type granite and its felsic enclaves from the southern Beishan orogenic belt, a ...

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

Geological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Mineralogy, geochemistry, tectonic environment and origin of granodiorite in the east of Bideshk (Urumieh-Dokhtar magmatic zone)

Journal of Economic Geology, 2021
Introduction Granitoids are one of the most abundant and common igneous rocks in the continental crust and they formed the world's largest batholiths. They are widely distributed in Precambrian to Cenozoic orogenic belts (e.g., Raymond, 2002), but some ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)

Terra Nova, EarlyView.
ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Petrogenesis and Geochronology of A1-Type Rhyolites in the Late Late Triassic of the East Kunlun Orogenic Belt: Constraints on the End of the Paleo-Tethys Orogenic Event

, 2023
The rhyolites which are widely exposed to the northern margin of the East Kunlun orogenic belt were chosen as a research object to discern the post-orogenic tectonic evolution of the East Kunlun orogenic belt and reconstruct the post-collision orogenic ...

LATE PALEOZOIC CONTRASTING MAGMATISM OF THE EASTERN KAAKHEM MAGMATIC AREA (CENTRAL ASIAN OROGENIC BELT)

Geodynamics & Tectonophysics, 2022
Based on the isotope-geochronological (zircons, U-Pb method), petrogeochemical, and structural and petrologic data, the following paper provides a detailed description of the characteristics of the Late Paleozoic basic and granitoid magmatism in the eastern part of the Kaakhem magmatic area (Eastern Tuva).
