Western Carpathian mid-Permian Magmatism: Petrographic, geochemical, and geochronological data

Abstract

This study presents geochemical and geochronological data from rock samples collected from the Western Carpathian mountains, eastern Slovakia. Granite assemblages that intrude the Gemeric and Veporic Superunits were imaged using a petrographic microscope to determine rock textures and their mineral assemblages. Zircon grains from seven individual portions of the Gemeric granites (Hnilec, Betliar, Elisabeth Mine, Poproč plutons) and one from the Veporic unit (Klenovec pluton) were dated using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) and Secondary Ion Mass Spectrometry (SIMS). Eight individual portions of the Gemeric unit's Betliar pluton and seven from the Klenovec granite were analyzed for major and trace elements using Fusion Inductively Coupled Plasma (ICP) and Fusion ICP-mass spectrometry. We also report detrital zircon ages from a radiolarite from the Meliata Unit that overlies blueschist and harzburgite-lizardite serpentinite assemblages near the city of Dobšiná, Slovakia. We applied X-ray Diffraction to a sample from the serpentine rocks, which reveal the presence of lizardite. The data are available for re-use to compare to future analyses of these Permian-age granites found in the Carpathian Mountains or similar Permiam assemblages elsewhere more broadly. Data reported in this article relates to G. Villaseñor, E.J. Catlos, I. Broska, M. Kohút, Ľ. Hraško, K. Aguilera, T.M. Etzel, J.R. Kyle, and D.F.
