Neodymium (Nd) concentrations, Nd radiogenic isotopes (143Nd/144Nd) and Nd stable isotopes (d146/144Nd) for chondritic meteorites, terrestrial basalts and mantle rocks, and rock reference materials.

Pyrite samples from selected sedimentary organic-rich formations or associated igneous and metamorphic rocks were analysed by conventional S isotopic analysis. Pyrites were measured in order to provide insights into their origin. Light and variable S isotope compositions in pyrite have been used to infer the influence of sulphate-reducing bacteria (and subsequent Se precipitation by sulphate-reducing microbes), whereas heavier S isotope compositions indicate a non-biological origin (i.e. physical and chemical diagenesis).

Organic carbon, total nitrogen, total reduced sulfur and carbonate-associated sulfur isotopes measured on decarbonated stromatolite samples from the Paranoa Group (1.1 Ga).

Organic carbon and bulk nitrogen isotope data for black shale samples from six different drill cores with varying distance from the major Zn ore body (HYC) in the McArthur basin. Data show trends with distance in d15N and C/N ratios. A more detailed interpretation is provided in Stüeken, E.E., Gregory, D.D., Mukherjee, I. and McGoldrick, P., 2021. Sedimentary exhalative venting of bioavailable nitrogen into the early ocean. Earth and Planetary Science Letters, 565, p.116963.

This data set consists of sets of qualitative data in the form of vulnerability questionnaires (referred to as tool 1) and interviews (referred to as Tool 2) from 4 communities - 2 in Northern Ghana and 2 in Burkina Faso.

We present new age models for the Ediacaran-Cambrian which lacks a robust global temporal framework. This interval marks the radiation of animals, but there are major uncertainties in the evolutionary dynamics of this critical radiation and its relationship to changes in palaeoenvironmental changes. Here we present global data from 130 successions that enable us to create four new possible global age models (A to D) for the interval 551–517 million years ago (Ma). These models comprise composite carbonate carbon isotope (δ13Ccarb) curves, which are anchored to radiometric ages and consistent with strontium isotope chemostratigraphy, and are used to calibrate metazoan distribution in space and time. These models differ most prominently in the temporal position of the basal Cambrian negative δ13Ccarb excursion (BACE). Two age models (A and B) place the BACE within the Ediacaran, and yield an age of ~538.8 Ma for the Ediacaran-Cambrian boundary; however models C and D appear to be the most parsimonious and may support a recalibration of the boundary age by up to 3 Myr younger. All age models reveal a previously underappreciated degree of variability in the terminal Ediacaran, incorporating notable positive and negative excursions that precede the BACE. Nothwithstanding remaining uncertainties in chemostratigraphic correlation, all models support a pre-BACE first appearance of Cambrian-type shelly fossils in Siberia and possibly South China, and show that the Ediacaran-Cambrian transition was a protracted interval represented by a series of successive radiations. Data were compiled by Fred Bowyer, with support from Andrey Yu. Zhuravlev, Rachel Wood, Maoyan Zhu, Graham Shields, Ying Zhou, Chuang Yang, Simon Poulton, Dan Condon, Andrew Curtis.

Dihedral angle data and bulk rock P2O5 concentrations for cumulates from the Skaergaard Intrusion of East Greenland. The data were used to constrain the thickness of the mushy layer at the point in the stratigraphic where apatite arrives as a liquidus phase. The work was published: Holness et al.
