Stratigraphic, geochronologic, and geochemical patterns of Neoproterozoic to Cambrian
sedimentary and volcanic rocks in Utah, Nevada, and SE Idaho record a dynamically …

Stromatolites are abundant in shallow marine sediments deposited before the evolution of
animals, but in the modern ocean they are restricted to locations where the activity of …

Abstract Death Valley (California, USA) hosts iconic Cryogenian snowball Earth deposits,
but the lack of direct geochronological constraints has permitted a variety of correlations and …

Abstract The Mesoproterozoic–Neoproterozoic sedimentary succession of the eastern part
of the Siberian Craton consists of several unconformity-bounded, kilometer-scale siliciclastic …

The primary mineralogy of marine carbonate precipitates has been a crucial factor in
constraining the major element composition of ancient oceans. Secular changes in …

The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to
an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of …

Abstract The upper Tonian ChUMP (Chuar-Uinta Mountains-Pahrump) strata of the
southwestern USA are hypothesized to be regional correlatives and to record a time of rift …

Neoproterozoic to Cambrian isolation of Laurentia during the breakup of Rodinia was
associated with multiple large igneous provinces, protracted multiphase rifting, and variable …

Biostratigraphy underpins the Phanerozoic time scale, but its application to pre-Ediacaran
strata has remained limited because Proterozoic taxa commonly have long or unknown …

The reason for the abundance of dolomite lithologies in Earth's early geological record
