The N ano SIMS ion probe is a new‐generation SIMS instrument, characterised by superior
spatial resolution, high sensitivity and multi‐collection capability. Isotope studies of certain …

The carbonate factories model, as defined at the beginning of the century, provides a
subdivision of marine carbonate sediment production‐systems based on the style of …

A mechanistic understanding of relationships between global glaciation, a putative second
rise in atmospheric oxygen, the Shuram carbon isotope excursion, and the appearance of …

Ooid shoals, sedimentary structures consisting of carbonate grains, are often used as
proxies to explore changes in seawater chemistry over Earth history. Despite their …

Carbonate minerals have precipitated from seawater for at least the last 3.8 billion years, but
changes in the physical and chemical properties of carbonate rocks demonstrate that the …

Abstract The Araripe Basin, located in northeastern Brazil, originated during the Gondwana
continental break-up responsible for the opening of the South Atlantic during the Early …

Since a NanoSIMS high-resolution secondary ion mass spectrometry (SIMS) instrument was
first used for cosmochemistry investigations over a decade ago, both interest in NanoSIMS …

Signals indicative of paleo-seawater rare earth element (REE) composition and microbial
activity were identified in marine ooids from the Lower Triassic of South China using in situ …

The origin and micro-texture of ooids remain controversial. This study presents a review of
microstructure of ooids and explains the origin of microstructures in Cambrian ooids in the …

Ooid formation remains elusive despite their importance as palaeoclimatic indicators and
important contributors to global carbonate budget. Based on stable isotopes, nutrient and …
