The orthogneisses of the Orlica–Śniez2nik complex (West Sudetes, Poland): geochemical characteristics, the importance of pre-Variscan migmatization and constraints on the cooling history
TL;DR: In this paper, geochemical analyses in combination with Rb-Sr (whole-rock, phengite, biotite) and U-Pb zircon ages provide important constraints on the magmatic, metamorphic and structural evolution of the Gieraltow gneisses from the Orlica-Śniez2nik complex (West Sudetes).
Sm-Nd and U-Pb dating of high-pressure granulites from the Zlote and Rychleby Mts (Bohemian Massif, Poland and Czech Republic)
TL;DR: In this article, the authors show that the central grain parts of zircon from this sample yielded a large spread in apparent 206 Pb/ 238 U SHRIMP ages (c. 462-322 Ma) with a distinct cluster at c. 365 Ma.

Numerical calibration of the Devonian-Carboniferous boundary: Two new U-Pb isotope dilution–thermal ionization mass spectrometry single-zircon ages from Hasselbachtal (Sauerland, Germany)
TL;DR: In this paper, the authors performed U-Pb isotope dilution-thermal ionization mass spectrometry (ID-TIMS) analyses on (sub)microgram-sized single zircons and zircon fragments extracted from two metabentonites (beds 79 and 70) in the lowermost Tournaisian part of the section.

The Numerical Age of the Upper Frasnian (Upper Devonian) Kellwasser Horizons: A New U-Pb Zircon Date from Steinbruch Schmidt (Kellerwald, Germany)
Abstract: Steinbruch Schmidt (Kellerwald, Germany) is probably the world’s most famous locality that exposes the late Frasnian anoxic events (Kellwasser Crisis). A 3‐cm‐thick bentonite layer (Bed 36) is intercalated between the two Kellwasser horizons and can be precisely assigned to the Upper rhenana conodont Zone. Twenty‐four U‐Pb ID‐TIMS (isotope dilution–thermal ionization mass spectrometry) analyses of single zircons extracted from this layer yielded 17 concordant results, which form an elongated cluster along concordia. The oldest point of this cluster is assumed to represent the lowest amount of Pb loss, and its 206Pb/238U age of \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc}

Two new Emsian (Early Devonian) U–Pb zircon ages from volcanic rocks of the Rhenish Massif (Germany): implications for the Devonian time scale
TL;DR: In this article, two new U-Pb isotope dilution-thermal ionization mass spectrometry (ID-TIMS) zircon ages were obtained from volcanic rocks of the Rhenish Massif (Germany).
