Orbitally‐Driven Nutrient Pulses Linked to Early Cambrian Periodic Oxygenation and Animal Radiation Open
During the Cambrian Explosion, episodic radiations of major animal phyla occurred in concert with repeated coupled carbon‐sulfur isotope excursions. These isotope patterns are thought to reflect oscillations in atmospheric and shallow‐mari…

Dynamic Evolution of the Transcrustal Plumbing System in Large Igneous Provinces: Geochemical and Microstructural Insights from Glomerocrysts and Melt Inclusions Open
The nature of the magma plumbing system of Large Igneous Provinces is still poorly understood. Among these exceptional magmatic events from Earth's past, the end-Triassic Central Atlantic Magmatic Province (CAMP) and the end-Cretaceous Dec…

Tracing the evolution of the world's first mined bauxite from palaeotopography to pyritization: Insights from Minjera deposits, Istria, Croatia Open
The Minjera bauxites are the first analysed and mined bauxites in the world. They are a group of pyritised bauxites situated in northern Istria, developed during the subaerial exposure phase which marked a major part of the Late Cretaceous…

Controls on the Termination of Cretaceous Oceanic Anoxic Event 2 in the Tarfaya Basin, Morocco Open
Oceanic Anoxic Event 2 (OAE2) has been the focus of considerable research, but biogeochemical dynamics during the recovery from the carbon cycle disturbance largely remain unknown. Here, we present a high-resolution reconstruction of water…

Modelling sulfate concentrations in the global ocean through Phanerozoic time Open
Understanding the long-term variations in seawater sulfate concentrations ([SO 4 2− ] sw ) is crucial to our understanding of the dynamic relationships between the sulfur, carbon, calcium and oxygen cycles, and their influence on the habit…

Anomalies of sulfur compound-specific molecular fossils link terrestrial ecosystem collapse to the end-Triassic crisis Open
The end-Triassic mass extinction (ETE), one of the “Big Five” in Earth history, was triggered by Central Atlantic Magmatic Province (CAMP) volcanism, releasing voluminous CO2, SO2 and halocarbons, which affected global marine a…

The transcrustal plumbing system of Large Igneous Provinces: Insights from glomerocrysts and melt inclusions Open
The magma plumbing system throughout the entire transcrustal section of Large Igneous Provinces (LIPs) is still poorly understood. Among the most voluminous LIPs, the Central Atlantic Magmatic Province (CAMP [1], ca. 201 Ma) and the Deccan…

Spatially heterogenous seawater δ34S and global cessation of Ca-sulfate burial during the Toarcian oceanic anoxic event Open
The early Toarcian of the Early Jurassic saw a long-term positive carbon-isotope excursion (CIE) abruptly interrupted by a significant negative excursion (nCIE), associated with rapid global warming and an oceanic anoxic event (T-OAE, ∼183…

Carbon, sulphur, and mercury geochemistry in a crater lake in the Siberian Traps Open
In the Siberian Traps Large igneous province (LIP), the emplacement of magma in sedimentary strata led to explosive release of volatiles and the formation of large pipe structures with explosion craters. Of the hundreds of pipes present, s…

Soil and plant-biochemical factors influencing the mobilization uptake of chromium, uranium and plutonium by plants Open
It is a well known phenomenon that many plant species, including important agricultural species, have the ability to absorb toxic metals. This is a major mechanism by which toxic metals enter the food chain, and is an especially important …
