Thermochronological constraints on the post-Variscan exhumation history of the southeastern Bohemian Massif (Waldviertel and Weinsberg Forest, Austria): palaeogeographic and geomorphologic implications

Autor: Ewald Hejl, Bianca Heberer, Bernhard Salcher, Gert Sekyra, Peter Van den haute, Jaromír Leichmann

Publikováno v: International Journal of Earth Sciences. 112:1203-1226

Resolving the Mesozoic and Cenozoic palaeogeography and geomorphologic development of outcropping Variscan basement is a pre-condition for the understanding of central European geodynamics. For our study, we have applied apatite fission-track (AFT) a

Synchysite was identified in the Rožná uranium deposit in a quartz–carbonate–sulfide vein, which is a part of the late (post-uranium and, post-Variscan) stage of the development of the hydrothermal system. The synchysite forms needles or lamell

Origin and the Silurian odyssey of the Brunovistulian terrane: paleomagnetic evidence from the Brno Massif (central Europe)

Autor: Magdalena Pańczyk, Jerzy Nawrocki, Jaromír Leichmann

The Brno Massif forms a part of larger tectonostratigraphic unit named the Brunovistulian Terrane (BVT) that is one of crustal block of Europe with the Neoproterozic basement. However, the Neoproterozoic orogenic belt was developed in wide area i.e.

Dual imaging of uranium ore by Laser Ablation Inductively Coupled Plasma Mass Spectrometry and Laser Induced Breakdown Spectroscopy

Autor: Viktor Kanický, Juraj Mozola, Jan Dobeš, Veronika Faltusová, Markéta Holá, Jaromír Leichmann, Ivo Krempl, Karel Novotný, Vojtěch Wertich, Martin Kubeš

Publikováno v: Spectrochimica Acta Part B: Atomic Spectroscopy. 186:106312

The great potential in combining two elemental imaging techniques - Laser Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) is demonstrated for uranium ore sample investigation. Dual ima

Metamictization and fluid-driven alteration triggering massive HFSE and REE mobilization from zircon and titanite: Direct evidence from EMPA imaging and LA-ICP-MS analyses

Autor: Viktor Kanický, Radek Škoda, Martin Kubeš, Jaromír Leichmann, Vojtěch Wertich, Markéta Holá, Juraj Mozola

Publikováno v: Chemical Geology. 586:120593

The major and trace element composition of the main HFSE-bearing phases from highly evolved miaskitic syenites has been investigated to assess their stability, an important control on HFSE retention and mobility during post-magmatic hydrothermal acti

Mid-Ediacaran bimodal magmatism and peri-Baltic affinity of the Brunovistulian terrane documented by the U-Pb isotope and palaeomagnetic data from the Brno Massif (Central Europe)

Autor: Jaromír Leichmann, Jerzy Nawrocki, Magdalena Pańczyk

Publikováno v: Precambrian Research. 358:106147

Palaeomagnetic and isotope (U-Pb, 40Ar-Ar39) studies were conducted in the area of the Brno Massif (Central Europe). The basaltic and granitic dykes, so far regarded as Silurian, were sampled in four localities. New U-Pb isotope ages and palaeomagnet

Experimental study of anisotropy of quartz dissolution and its role in fluid migration in rocks

Autor: Šárka Benedová, Jaromír Leichmann

Publikováno v: Acta Geodynamica et Geomaterialia. :193-200

Quartz dissolution in hydrothermal-metasomatic processes is common feature in magmatic and metamorphic quartz rich rocks. This experimental work aims to compare the dissolution of individual quartz faces and to clarify the role of mechanical defects
