Novel Mantle flow retrodictions reveal preferential material flow in the sublithospheric European mantleHans-Peter Bunge, Siavash Ghelichkhan & Jens Oeser
The Cenozoic tectonic evolution of Northern Europe involves a number of events that are difficult to reconcile with an intra-plate setting, including magmatic events and topographic changes that are located far from plate boundaries. It is entirely plausible to relate these events to sublithospheric processes in a vigorously convecting mantle. However, traditional mantle convection models are difficult to link to the spatiotemporal constraints provided by geologic archives, because their output invariably depends on the assumptions...
OneGeochemistry: Enabling a coordinated online global network of multiple distributed geochemical repositories and databasesKerstin Annette Lehnert , Lesley Wyborn , Dominik Hezel , Alexander Prent , Kirsten Elger , Geertje ter Maat , Marthe Klöcking & Jens Klump
Since the discipline of ‘geochemistry’ was first defined in 1838, geochemical data has been pervasively acquired and used in the Earth, environmental and planetary sciences and become fundamental for understanding past, present, and future processes in natural systems. Initially, geochemical data was published in hard-copy literature, but as analytical systems became computerised, major digital databases emerged (EarthChem, PetDB, OZCHEM and GEOROC) which revolutionised data access. They have proven the power of re-use of geochemical data...
Today, research data is widely available in digital form, datasets are easily accessible online and the dataset creator should consider it advantageous as this leads to greater uptake. However, the downside is that digital datasets can be easily copied, duplicated in multiple places, and re-published through more than one repository or service. Particularly with web services, mirroring resources is a common practice, especially in online GIS packages and dashboards. ‘Copy WMS link’ buttons are common,...
The European continental crust through detrital zircons from modern rivers: biasing effects in the detrital zircon recordPaula Castillo , Heinrich Bahlburg , Rodrigo Fernández , Mark Fanning & Jasper Berndt
We present U-Pb, Lu-Hf, and O isotopic data, as well as size-shape data for approximately 3700 detrital zircons from 15 European rivers. In combination with geomorphological information for each river basin (area, drainage length, and hypsometric curves), we evaluate the representativeness and biases affecting such datasets. The new data allow us to demonstrate that the detrital zircon record from major rivers represents all relevant geological events in Europe at the continental scale, with detrital zircon...
The Australian AuScope Virtual Research Environments (AVRE): a Flexible, Service-Oriented Geoscience Platform to Empower Researchers for the Global Challenges of Today and Those of the FutureJens Klump , Tim Rawling , Carsten Friedrich , Ulrich Engelke , Vincent Fazio & Lesley Wyborn
AuScope is Australia’s National Geoscience Research Infrastructure Program and seeks to provide a world-class research physical and digital infrastructure to help tackle Australia's key geoscience challenges. Launched in 2007, AuScope’s data-generating infrastructures range from VLBI telescopes to geochemistry/geochronology laboratories and geophysical data acquisitions. To utilise data collected by these infrastructures and equivalents elsewhere, the Australian Geoscience Research and Government communities have collaborated on building a suite of data portals, tools, software and virtual laboratories that...
Carbonatites do not exist in vacuum: carbonatite–rock interactions from experiment and nature, and implications for REE mineralisationMichael Anenburg
The igneous nature of carbonatites has been controversial for decades until experimental work in the 1960s and 1970s conclusively showed that carbonatite melts can exist in geologically reasonable conditions. The observation of natrocarbonatite eruptions at Ol Doinyo Lengai further confirmed their igneous nature. However, these lines of evidence for igneous carbonatites have been a red herring: many ideas, processes, and terms deriving from silicate magma systems were inaccurately projected into carbonatite systems. Instead, carbonatites should...
