A case for late-Archaean continental emergence from thermal evolution models and hypsometry
TLDR
Rey et al. as discussed by the authors investigated the continental freeboard predicted using different models for the cooling of the Earth and showed that constancy of the freeboard is possible throughout the history of the planet as long as the potential temperature of the upper mantle was never more than 110−210°C hotter than present.About:

The diversity and evolution of late-Archean granitoids: Evidence for the onset of “modern-style” plate tectonics between 3.0 and 2.5 Ga
TL;DR: A review of the nature, petrogenesis and global evolution of late-Archean granitoids and their geodynamic significance can be found in this article, where the authors classify granitoid types into four groups: volumetrically dominant and juvenile tonalites, trondhjemites and granodiorites (TTGs).
Journal ArticleDOI
Subduction styles in the Precambrian: Insight from numerical experiments
TL;DR: In this paper, a series of experiments using a 2D petrological-thermomechanical numerical model of oceanic subduction was conducted to investigate the dependence of tectono-metamorphic and magmatic regimes at an active plate margin on upper-mantle temperature, crustal radiogenic heat production, degree of lithospheric weakening and other parameters.
Journal ArticleDOI
Emergence of modern continental crust about 3 billion years ago
TL;DR: The continental crust provides a record of Earth's evolution and has been used to study the evolution of plate tectonics about 3 billion years ago as discussed by the authors, using a geochemical signature of continental crust.
Journal ArticleDOI
Atmospheric oxygenation caused by a change in volcanic degassing pressure
TL;DR: It is proposed that a decrease in the average pressure of volcanic degassing changed the oxidation state of sulphur in volcanic gases, initiating the modern biogeochemical sulphur cycle and triggering atmospheric oxygenation.

Atmospheric Evolution on Inhabited and Lifeless Worlds
TL;DR: In this article, the authors present a survey of the current understanding of the atmospheric evolution and climate on Earth, on other rocky planets within our Solar System, and on planets far beyond.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.
Journal ArticleDOI
Chronology of fluctuating sea levels since the triassic.
TL;DR: An effort has been made to develop a realistic and accurate time scale and widely applicablechronostratigraphy and to integrate depositional sequences documented in public domain outcrop sections from various basins with this chronostratigraphic framework.
Journal ArticleDOI
Hypsometric (area-altitude) analysis of erosional topography.
TL;DR: The percentage hypsometric curve (area-altitude curve) as discussed by the authors relates horizontal cross-sectional area of a drainage basin to relative elevation above basin mouth, and is used to measure the sinuosity of form and proportionate area below the curve.

TL;DR: Long-term sea level peaked at 100 ± 50 meters during the Cretaceous, implying that ocean-crust production rates were much lower than previously inferred, and presents a new sea-level record for the past 100 million years.
