GPlates Portal

4 February, 201916 November, 2014 by Michael Chin

The GPlates Portal is a free and interactive cloud-based tool that enables the visualisation of cutting-edge geoscience datasets. Using a published plate kinematic model, datasets can be reconstructed back through time to the Jurassic, 200 million years ago.

Currently, global satellite-derived vertical gravity gradient data can be visualised via the Portal, and global maps of free-air gravity anomalies and magnetic anomalies can be tectonically reconstructed.

The GPlates Portal is also the gateway to the Paleomap Maker, a web service designed to provide researchers with plate-tectonic data reconstruction and visualization services. The core reconstruction engine is powered by the cutting-edge open-source plate-tectonic reconstruction software, GPlates, and the visualization is made available by using Matplotlib Basemap Toolkit. … Read more…

Summary
Break-up–related extrusive magmatism, imaged in reflection seismic data as seaward-dipping reflectors (SDRs), extends sym- metrically along the volcanic margins of the Atlantic Ocean. Recent research found distinct along-margin variations in the distribution of SDRs, and abundance of volcanic material was found to be spatially linked to transfer fault systems. These segmented the propagating rift that later developed into the ocean, and are interpreted as rift propa- gation barriers. Based on these observations, we develop a numeri- cal model, which shows that rift-parallel mantle flow and locally enhanced rates of volcanism are the result of delays in rift propaga- tion and segmented opening. … Read more…

Summary
New global marine gravity model from CryoSat-2 and Jason-1 reveals buried tectonic structure.

View the new gravity map in an online 3D portal!

Gravity models are powerful tools for mapping tectonic structures, especially in the deep ocean basins where the topography remains unmapped by ships or is buried by thick sediment. We combined new radar altimeter measurements from satellites CryoSat-2 and Jason-1 with existing data to construct a global marine gravity model that is two times more accurate than previous models. We found an extinct spreading ridge in the Gulf of Mexico, a … Read more…
