DETRITAL-ZIRCON GEOCHRONOLOGIC PROVENANCE ANALYSES THAT TEST AND EXPAND THE EAST SIBERIA - WEST LAURENTIA RODINIA RECONSTRUCTION
… position in the Neoproterozoic supercontinent Rodinia is a topic of continuing debate. Several reconstructions involving Laurentia and Siberia have been proposed, including the east Siberia-west Laurentia connection. The east Siberia-west Laurentia Rodinia reconstruction includes …

Mesoproterozoic Basement From The Central And Southern Appalachians Reveal High-temperature Magmatic Conditions And Non-laurentian Origin Of Earth’s Most Zircon Fertile Magmas
… led to the formation of the supercontinent Rodinia. One unique characteristic of the Grenville Orogeny is that it produced a volumetrically significant amount of zirconium- (Zr) enriched granitoids, evidently more than any period both prior to and after the Grenville. To investigate this …

Cu2cl: a Cuda-To-Opencl Translator for Multi- and Many-Core Architectures
… several applications from the CUDA SDK and Rodinia benchmark suite. CU2CL's translation times are reasonable, allowing for many applications to be translated at once. The number of manual changes required after executing our translator on CUDA source is minimal, with some compiling and …

A Task-based Programming Methodology Using MCA Standards for Multicore Systems
… MTAPI RTL implementation using applications from Rodinia and BOTS. We compare our MTAPI implementation with the Siemens MTAPI and with GCC-OpenMP, and observe that our MTAPI outperforms Siemens MTAPI significantly on the embedded board and competes favorably with GCC-OpenMP on both testbeds.

Re-Os geochronology and geochemistry of Proterozoic sedimentary successions
… the West African craton during the assembly of Rodinia is required. New Re-Os geochronology for the Ballachulish Slate Formation of the Dalradian Supergroup, Scotland yields a depositional age of 659.6 ± 9.6 Ma. The Re-Os age represents a maximum age for the glaciogenic Port Askaig Formation and …

The geochemistry and geochronology of the barby formation in the sinclair area, Southern Namibia
… which took place during the assembly of the Rodinia supercontinent. It is slightly younger at 1204 ±9 Ma and reflects the end of subduction-related volcanism due to the collision of Namaqua terranes with the Konkiep Terrane. The Spes Bona syenite and the Barby units have Lu-Hf crustal …

Pre-rift evolution of Malawian high-grade basement rocks
… early stages of the East African orogen or Rodinia break-up at 900-800 Ma while the second occurred during the late stages of the East African orogen at 650-600 Ma. Possible remnants of the Kuunga Orogeny are recorded in Chilumba and Maganga as an amphibolite facies metamorphic event which …

The Neoproterozoic São Francisco Basin, central Brazil: tectonic evolution, paleoclimate, and mineral systems
… accumulated during breakup of the supercontinent Rodinia. Deposition was punctuated by globally correlative Sturtian glacial deposits (ca. 717-660 Ma). Copious post-glacial organic matter and pyrite-rich siltstones formed during the subsequent passive margin stage. The overlying Bambuí Group is a …

The thermal and metamorphic evolution of the Northern Highlands Terrane, Scotland
… c. 600 Ma, possibly related to the break-up of Rodinia at that time. A potentially important heat source in orogenic systems, like those preserved in Scotland, is the thermal energy dissipated during deformation, otherwise known as shear heating. It is important to consider to how shear heating …

Investigating the metamorphic evolution of reworked terrains.
… which existed on a margin of the supercontinent Rodinia. As an additional result of this study, the P-T evolution of the Grampian event (c. 460 Ma) of the Caledonian Orogeny in both Shetland and Scotland has been well constrained.

Supercontinents and glaciation: a perspective from western Gondwana.
… the breakup of south-western Congo Craton from Rodinia. The northern Paraguay Belt in South America developed in response to the collision between the Amazonian Craton, the Rio Apa Block, the São Francisco Craton and the Paranapanema Block. The alleged ‘Brasiliano’ age (~620 Ma) of orogenesis …

Metamorphic and crustal evolution of Australian-Antarctic Proterozoic margins
… of the Australian–Antarctic continent in the Rodinia system. Despite its significance, precise details of the Mesoproterozoic metamorphic evolution of some constituent terranes of the MAFWO are unclear. A metamorphic framework for the orogen in its entirety is also non-existent. To address …

Space-Time Analysis of Magmatism: Evidence for a Early Cryogenian Plume Track in Eastern Laurentia
In the Grenville age basement rocks of Virginia and North Carolina, nearly thirty Cryogenian volcanic/plutonic complexes have been recognized. A-type granites and rhyolites dominate the igneous complexes within the Cryogenian Magmatic Province (CMP), but compositional variations range from gabbro …

Palaeozoic Palaeomagnetism of South-Eastern Australia
… history of Gondwana following the break-up of Rodinia (or perhaps Pannotia) to the amalgamation into Pangaea has great implications in many disciplines in Earth sciences, but remains largely unknown. Among the apparent polar wander (APW) paths published for Gondwana in the last few decades, …

Effectiveness of program transformations and compilers for directive-based GPU programming models
Accelerator devices like the General Purpose Graphics Computing Units (GPGPUs) play an important role in enhancing the performance of many contemporary scientific applications. However, programming GPUs using languages like C for CUDA or OpenCL requires relatively high investment of time and the …
