TL;DR: In this article, a comprehensive approach, combining phase equilibria, solubility experiments and melt inclusion and textural analyses, is presented to analyze the remarkable oscillatory zoning of anorthoclase feldspar megacrystals erupted from the lava lake of Erebus volcano, Antarctica.
Preliminary Integrated Chronostratigraphy of the AND-1B Core, ANDRILL McMurdo Ice Shelf Project, Antarctica

TL;DR: In this article, a relatively well-constrained age model was constructed for the upper 700 m of the AND-1B drill core, based on the available diatom biostratigraphic constraints and 40 Ar/39 Ar ages.
Petrology and Geochemistry of the AND-1B Core, ANDRILL McMurdo Ice Shelf Project, Antarctica
Massimo Pompilio,Nelia W. Dunbar,A. C. Gebhardt,D. Helling,Gerhard Kuhn,Philip R. Kyle,Robert M. McKay,Franco M Talarico,Slawek Tulaczyk,S. W. Vogel,T. I. Wilch +10 more
TL;DR: In this paper, preliminary data and results on petrology and geochemistry of AND-1B core were reported, and a detailed analysis of the petrological and geochemical properties were presented.
Journal ArticleDOI
Advancements and best practices for analysis and correlation of tephra and cryptotephra in ice
TL;DR: In this article, the authors developed a flexible workflow for preparation of tephra and cryptotephra samples to allow accurate and robust geochemical fingerprinting, which is fundamental to tephrochronology.
Journal ArticleDOI
Ice motion and mass balance at the Allan Hills blue-ice area, Antarctica, with implications for paleoclimate reconstructions
Nicole E. Spaulding,Vandy Blue Spikes,Gordon S. Hamilton,Paul Andrew Mayewski,Nelia W. Dunbar,Ralph P. Harvey,John Schutt,Andrei V. Kurbatov +7 more
TL;DR: In this paper, a new surface-balance and ice-motion dataset derived from high-precision GPS measurements from a network of steel poles within three icefields of the Allan Hills blue-ice area, Antarctica, was presented.
