OCTOPUS: an open cosmogenic isotope and luminescence database

We present a database of cosmogenic radionuclide and luminescence measurements in fluvial sediment. With support from the Australian National Data Service (ANDS) we have built infrastructure for hosting and maintaining the data at the University of Wollongong and making this available to the research community via an Open Geospatial Consortium (OGC)-compliant web service. The cosmogenic radionuclide (CRN) part of the database consists of 10Be and 26Al measurements in modern fluvial sediment samples from across the globe, along with ancillary geospatial vector and raster layers, including sample site, basin outline, digital elevation model, gradient raster, flow-direction and flow-accumulation rasters, atmospheric pressure raster, and CRN production scaling and topographic shielding factor rasters. Sample metadata are comprehensive and include all necessary information for the recalculation of denudation rates using CAIRN, an open-source program for calculating basin-wide denudation rates from 10Be and 26Al data. Further all data have been recalculated and harmonised using the same program. The luminescence part of the database consists of thermoluminescence (TL) and optically stimulated luminescence (OSL) measurements in fluvial sediment samples from stratigraphic sections and sediment cores from across the Australian continent and includes ancillary vector and raster geospatial data. The database can be interrogated and downloaded via a custom-built web map service. More advanced interrogation and exporting to various data formats, including the ESRI Shapefile and Google Earth\u27s KML, is also possible via the Web Feature Service (WFS) capability running on the OCTOPUS server. Use of open standards also ensures that data layers are visible to other OGC-compliant data-sharing services. OCTOPUS and its associated data curation framework provide the opportunity for researchers to reuse previously published but otherwise unusable CRN and luminescence data. This delivers the potential to harness old but valuable data that would otherwise be lost to the research community

OCTOPUS database (v.2)

OCTOPUS v.2 is an Open Geospatial Consortium (OGC) compliant web-enabled database that allows users to visualise, query, and download cosmogenic radionuclide, luminescence, and radiocarbon ages and denudation rates associated with erosional landscapes, Quaternary depositional landforms, and archaeological records, along with ancillary geospatial (vector and raster) data layers. The database follows the FAIR (Findability, Accessibility, Interoperability, and Reuse) data principles and is based on open-source software deployed on the Google Cloud Platform. Data stored in the database can be accessed via a custom-built web interface and via desktop geographic information system (GIS) applications that support OGC data access protocols. OCTOPUS v.2 hosts five major data collections. CRN Denudation and ExpAge consist of published cosmogenic 10Be and 26Al measurements in modern fluvial sediment and glacial samples respectively. Both collections have a global extent; however, in addition to geospatial vector layers, CRN Denudation also incorporates raster layers, including a digital elevation model, gradient raster, flow direction and flow accumulation rasters, atmospheric pressure raster, and CRN production scaling and topographic shielding factor rasters. SahulSed consists of published optically stimulated luminescence (OSL) and thermoluminescence (TL) ages for fluvial, aeolian, and lacustrine sedimentary records across the Australian mainland and Tasmania. SahulArch consists of published OSL, TL, and radiocarbon ages for archaeological records, and FosSahul consists of published late-Quaternary records of direct and indirect non-human vertebrate (mega)fauna fossil ages that have been systematically quality rated. Supporting data are comprehensive and include bibliographic, contextual, and sample-preparation- and measurement-related information. In the case of cosmogenic radionuclide data, OCTOPUS also includes all necessary information and input files for the recalculation of denudation rates using the open-source program CAIRN. OCTOPUS v.2 and its associated data curation framework allow for valuable legacy data to be harnessed that would otherwise be lost to the research community. The database can be accessed at https://octopusdata.org (last access: 1 July 2022). The individual data collections can also be accessed via their respective digital object identifiers (DOIs) (see Table 1)

Zircon Geochronology and Tectonic Evolution of Eclogites from the Beishan and Qinling Orogens, China

Central Asia is host to some of the best examples of ultra-high pressure metamorphic rocks in the world. The study sites located in Beishan and Qinling Orogens contain examples of these high pressure rocks, called eclogites. They are an evidence of ancient continental collisions and their age and composition provide invaluable information about tectonic mechanics during collisions. This study focuses on geochronology of eclogites sampled from Beishan and Qinling Orogens. The Beishan eclogite, occurs as small mafic pods within highly deformed gneisses. The geological context and geochemistry of these eclogites determined in this study suggests they were originally rift-related MORB-type basalts rather than discrete fragments of oceanic crust, as previously thought. Zircon dates obtained from the Beishan eclogite reveal peak metamorphism at 466 ± 27 Ma, which is concordant with the literature. However, U/Th ratios in zircon cores (ca. 880 Ma) are too low to have crystallized from mafic magma and therefore represent xenocrystic cores or previous metamorphic event rather than age of the protolith. The maximum age of the eclogite protolith is constrained by the crystallization age of the country rock orthogneiss at 920 ± 14 Ma. The end of retrogression metamorphism in the studied terrane was constrained by granitic vein that intruded the eclogite at 424 ± 8.6 Ma. This study provides the age for this rock for the first time. From evidence gathered for Beishan Orogen, this study proposes new tectonic model for initial stage of orogen development. The Qinling eclogites did not yield significant amount of zircons, so they could not be dated with certainty. One zircon was dated at 490 ± 83 Ma which is consistent with metamorphic age established in literature, but statistically they cannot be used as a reliable age. However, its remarkably well-preserved eclogite facies mineral assemblage, that is contrary to Beishan eclogite, suggest diversity of dynamics during high pressure terrane exhumation. Lastly, this study has found possible connection between extrusive tectonics of India- Eurasia collision and its long distance (~600 km) effects on Beishan terrane. Here named, “Cenozoic Thermal Event”, led to reset of metamict zircons in the eclogite, where new ages correspond to major tectonic developments in Tibetan Plateau. This finding provides a new, previously undocumented relationship between tectonism and reset of the zircon geochronometers, which may have significant implications for future geochronology of crustal-scale fault systems

Magmatic records from the Karakoram terrane: U–Pb zircon ages from granites and modern sediments in the Nubra Valley, NW Himalaya

The Karakoram terrane is a sliver of peri-Gondwana continental crust preserved within the Karakoram and Saltoro ranges in Ladakh, India. It became a part of Eurasia during the Jurassic, and until Late Cretaceous its southern margin was an active continental margin represented by the Karakoram (Arc) Batholith. Its magmatism is thought to be extinguished during Late Cretaceous by collision with the Shyok ophiolite, however, geochronological data are limited. The Karakoram terrane is a key element in the geodynamics of Himalaya and more studies are needed to improve geological understanding and tectonic evolution of the southern margin of Eurasia pre- and post- final continental collision with the Indian continent. We present petrographic, geochemical, and geochronological observations for anatectic magmatism which formed granitic intrusions within the terrane at c. 14 Ma and 12 Ma. Results from detrital zircon dating of modern sediments from the Karakoram terrane reveal three distinct age populations at c. 108, 82, and 13 Ma which correspond to known geological events. Current geochronological data for the Karakoram terrane indicate presence of two major magmatic episodes, the first occurred during Jurassic–Cretaceous and was related to subduction processes, and second, occurred during the Miocene and was related to the anatexis of the Karakoram lithosphere upon the terminal continental collision. The intervening magmatic events are still uncharacterised
