The data set contains grain size distributions, organic matter (OM) content and trace metal distribution (including Fe, Zn, Cu, Cr and Pb) of 37 shallow cores of sediments sampled from dams across the Limpopo River Basin. The dams include: Gaborone, Lotsane and Shashe dams in Botswana;...

In-situ rock deformation and micron-scale crack network evolution: a high-resolution time-resolved x-ray micro-tomography dataset

Cartwright-Taylor, Alexis | Main, Ian | Butler, Ian | Fusseis, Florian | Flynn, Michael | King, Andrew

2020

This collection comprises two time-series of 3D in-situ synchrotron x-ray microtomography (μCT) volumes showing two Ailsa Craig micro-granite samples (ACfresh02 and ACHT01) undergoing triaxial deformation. These data were collected in-situ at the PSICHE beamline at the SOLEIL synchrotron,...

2024

The dataset consists of eleven spreadsheet tabs, each tab containing lipid biomarker palaeothermometry (air temperature reconstructions) and bulk organic carbon isotope data from individual lignites that are known to stratigraphically span the Cretaceous-Palaeogene (K-Pg) boundary....

High precision zircon U-Pb data for plutonic rocks from the Masirah and Ra's Madrakah ophiolites, South East Oman

Jansen, Max | MacLeod, Christopher | Lissenberg, Johan | Parkinson, Ian | Condon, Daniel

2024

Zircon U-Pb isotope data are presented for eight plutonic rocks from the Masirah ophiolite and one plutonic rock from the Ra's Madrakah ophiolite (South East Oman). These data constrain the age of formation of the two ophiolite nappes exposed on Masirah Island (early Cretaceous), whereas two...

Stoer Group and Sibley Group nitrogen geochemistry in red beds

Stüeken, Eva E. | Fralick, Philip | Prave, Anthony R.

2024

Nitrogen abundances in red shales are shown to be suitable as a biosignature that may be applicable to red beds on Mars. The data set includes organic carbon and nitrogen abundances and isotopic ratios, carbonate carbon and oxygen isotope ratios, and metal abundances. We evaluate potential...

40Ar/39Ar geochronology of basaltic samples from Bruce Bank and Jane Bank of the Scotia Sea

Riley, Teal

2023

The datasets refer to the dating of three basaltic samples collected from Bruce Bank and Jane Bank in the southern Scotia Sea. The samples were dredged from depths between 850 -1900 m from steep scrap slopes at two locations (DR.225: 59.927 degrees S, 39.154 degrees W; DR.84: 62.468 degrees...
