TL;DR: In this article, the authors used geochemical and geochronological constraints of a suite of preserved mafic-ultramafic rocks in the Paleoproterozoic Capricorn Orogen of Western Australia to reveal ophiolites, continental ribbons and aborted rifts.

TL;DR: In this paper, two compositionally heterogeneous cordierite-spinel-bearing granulites from Vizianagaram, Eastern Ghats Province (EGP), India, were investigated to provide P-T-time constraints using petrography, phase equilibrium modelling, U-Pb geochronology, the rare earth element (REE) composition of zircon and monazite, and Ti-in-zircon thermometry.

TL;DR: In this article, it has been shown that Quaternary ice sheets were profoundly, and arguably catastrophically, influenced by the operation of transitory ice streaming, and the resulting icebergs cooled North Atlantic waters enough to alter ocean circulation and produce ~4°C flips in climate on abrupt time scales.

TL;DR: This article examined the stratigraphy of the megaridges using new decimetric-resolution geophysical data correlated to sediment cores to test hypothetical tidal vs glacial modes of formation.

TL;DR: Numerical simulations shed light on how such an ice shelf could have formed, its dynamics and most likely configuration are shed, and it is suggested that grounding on the Lomonosov Ridge requires complete Arctic ice shelf cover.
