Results of Studying the Material Composition and U-Pb (LA-ICP-MS) Age of Detrital Zircons From Terrigenous Rocks of the Vanavara and Oskobinskaya Formations of the Kamov Arch of the Baikit Antelise

Georesursy
The paper presents the results of studies on sandstones from the Vanavara and Oskobinskaya formations, which are part of the Nepa and Torskiy regional stratigraphic horizons, respectively. These formations were studied using the core from the Yur-92 deep

Palаeomagnetism of the Vendian traps of Volyn, southwestern margin of the East European platform. P. 1: palаeomagnetic directions and poles

, 2022
In Earth’s geological evolution the Vendian is significant because: 1) it preceded the «Cambrian Evolutionary explosion» when the multicellular organisms became suddenly much more diverse; 2) it is associated with the global tectonic and palaeogeographic

New Late Vendian palaeogeography of Baltica and the TESZ

, 2004
New palaeomagnetic poles obtained from the Vendian tuffs and basalts of western Ukraine indicate the necessity of a substantial revision of the Late Vendian-Early Cambrian palaeogeography of the Baltic plate. The palaeopole calculated for the most stable

Deep processes and magmatic activity of the Volyn-Podolian plate

Геофизический журнал, 2010
Conditions of formation of basalts of the Volyn-Podolian plate (VPP) have been considered. In Vendian primary melts which were close by their composition to picritic gabbro were differentiated at the depth of 30-35 km during first two stages of ...
