TLDR
In this paper, a probabilistic kernel density analysis of large databases (up to nearly 40,000 samples) of U/Pb zircon ages suggests an optimum bandwidth of 25-30 My for many key features, yielding approximately 40 peaks with confidence levels of c ǫ ≥ 0.9.

The supercontinent cycle: A retrospective essay

TL;DR: In this article, the authors trace the development of ideas concerning long-term episodic orogeny and continental crust formation, such as those embodied in the chelogenic cycle, through the first realization that such episodicity was the manifestation of the cyclic assembly and breakup of supercontinents, to the surge in interest in supercontinent reconstructions.

The continental record and the generation of continental crust

TL;DR: In this paper, detrital zircons have been used to estimate that at least 60% to 70% of the present volume of the continental crust had been generated by 3 Ga, which may have been linked to the onset of signifi cant crustal recycling through subduction at convergent plate margins.
Journal ArticleDOI

Archean upper crust transition from mafic to felsic marks the onset of plate tectonics

TL;DR: New geochemical proxies for MgO track the chemistry and evolution of Earth’s continental crust over 4 billion years, suggesting the onset of global plate tectonics at ~3.0 billion years ago.
Journal ArticleDOI

Secular change in metamorphism and the onset of global plate tectonics

TL;DR: In this article, thermal gradients of metamorphic rocks were analyzed for 456 localities from the Eoarchean to Cenozoic Eras to test the null hypothesis that thermal gradient through time did not vary outside of the range expected for each of these distinct plate tectonic settings.
Journal ArticleDOI

Statistical geochemistry reveals disruption in secular lithospheric evolution about 2.5 Gyr ago

TL;DR: The coincidence of the observed changes in geochemistry and crustal thickness with stepwise atmospheric oxidation at the end of the Archaean eon provides a significant temporal link between deep Earth geochemical processes and the rise of atmospheric oxygen on the Earth.

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.

Finite mixture models: McLachlan/finite mixture models

TL;DR: The important role of finite mixture models in statistical analysis of data is underscored by the ever-increasing rate at which articles on mixture applications appear in the statistical and geospatial literature.

Parameter estimation and inverse problems

TL;DR: "Parameter Estimation and Inverse Problems, 2/e" introduces readers to both Classical and Bayesian approaches to linear and nonlinear problems with particular attention paid to computational, mathematical, and statistical issues related to their application to geophysical problems.
