Upper cretaceous magmatic suites of the Timok magmatic complex [PDF]

Geološki Anali Balkanskoga Poluostrva, 2010
The Upper Cretaceous Timok Magmatic Complex (TMC) developed on a continental crust composed of different types of Proterozoic to Lower Cretaceous rocks. The TMC consists of the magmatic suites: Timok andesite (AT) - Turonian-Santonian, Metovnica

Cretaceous magmatism in the Antarctic Peninsula and its tectonic implications

Journal of the Geological Society, 2022
Periods of cessation, resumption and enhanced arc activity are recorded in the Cretaceous igneous rocks of the Antarctic Peninsula. We present new geochronological (laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) zircon U–Pb) analyses of 36 intrusive and volcanic Cretaceous rocks, along with LA-ICP-MS apatite U–Pb ...

A Paleogene magmatic overprint on Cretaceous seamounts of the western Pacific [PDF]

Island Arc, 2021
AbstractThe West Pacific Seamount Province (WPSP) represents a series of short‐lived Cretaceous hotspot tracks. However, no intraplate volcanoes in advance of petit‐spot volcanism erupted near a trench have been identified after the formation of the WPSP on the western Pacific Plate.

Fingerprints of the Kerguelen Mantle Plume in Southern Tibet: Evidence from Early Cretaceous Magmatism in the Tethyan Himalaya

The Journal of geology, 2020
Early Cretaceous magmatism suggested to be related with the Kerguelen mantle plume has been reported in both the eastern and western Tethyan Himalayan terrane.

Caribbean Plate margin evolution: constraints and current problems

Geologica Acta, 2006
Oceanic crust was generated at multiple spreading centres during the Jurassic and Early Cretaceous, forming a “proto-Caribbean” oceanic domain. During the Cretaceous, part of that crustal domain thickened into an oceanic plateau, of petrologic Mid-Ocean ...

Early Cretaceous displacement on the Tanymas thrust fault, Northern Pamir, Tajikistan, and regional tectonic implications

Journal of Asian Earth Sciences: X, 2023
An ongoing question in understanding the evolution of the Himalayan-Tibetan orogeny is how much of the observed upper crustal shortening and crustal thickness is related to the Cenozoic collision between India and Asia vs earlier tectonic events along ...

A review of the stratigraphic characteristics and age data of the main rock units in the Bor Metallogenic Zone (Timok Magmatic Complex) [PDF]

Journal of Mining and Metallurgy. Section A: Mining
This study reports on the stratigraphic characteristics of the main units and indicates the link between magmatism and mineralization in the Bor Metallogenetic Zone (BMZ)-the Timok Magmatic Complex (TMC).
