Resources

EarthByte endeavours to make a variety of geological and geophysical data sets available to the community with every publication and project collaboration.

Where possible, all our data sets are able to be visualised using GPlates. Furthermore, every GPlates release is accompanied by a sample data bundle which includes published reconstruct-able raster and vector data.

Our data sets are available below, and are attached to their publication or news item. When using these data please cite the relevant publication.

PyBacktrack 1.1 has been released as Python package and Docker image

by

PyBacktrack is a Python package that backtracks the paleo-water depth of ocean drill sites through time by combining a model of tectonic subsidence with decompaction of the site stratigraphic lithologies. PyBacktrack can also include the effects of mantle-convection driven dynamic topography on paleo-water depth, as well as sea-level variations. PyBacktrack provides a model of tectonic … Read more…

The interplay of dynamic topography and eustasy on continental flooding in the late Paleozoic

by

Abstract: Global sea level change can be inferred from sequence stratigraphic and continental flooding data. These methods reconstruct sea level from peri-cratonic and cratonic basins that are assumed to be tectonically stable and sometimes called reference districts, and from spatio-temporal correlations across basins. However, it has been understood that long-wavelength (typically hundreds of km) and … Read more…

AuScope reviews innovations of the ARC Basin Genesis HUB

The influence of carbonate platform interactions with subduction zone volcanism on palaeo-atmospheric CO2 since the Devonian

by

Abstract: The CO2 liberated along subduction zones through intrusive/extrusive magmatic activity and the resulting active and diffuse outgassing influences global atmospheric CO2. However, when melts derived from subduction zones intersect buried carbonate platforms, decarbonation reactions may cause the contribution to atmospheric CO2 to be far greater than segments of the active margin that lacks buried carbon-rich rocks and … Read more…

Abstract The motion of plates and continents on the planet’s surface are a manifestation of long-term mantle convection and plate tectonics. Present-day plate velocities provide a snapshot of this ongoing process, and have been used to infer controlling factors on the speeds of plates and continents. However, present-day velocities do not capture plate behaviour over … Read more…
