The complexity of cold chain conditions, the timeliness of delivery as well as the need to mitigate risk of any deviation are identified as critical challenges for successful large-scale vaccination. In the next few months, billions of doses of COVID-19 vaccines will need to be rapidly and safely administered to people around the world. COVID-19 vaccine logistics chain reliability and compliance -īureau Veritas and OPTEL partner together to launch V-TRACE, a complete and assured traceability solution for COVID-19 vaccines along the whole supply chainīureau Veritas, a world leader in testing, inspection, and certification, and OPTEL, a leading global provider of pharmaceutical supply chain traceability platforms, join forces to address the critical issue of reliability and traceability in COVID-19 vaccine logistics chains. This back-arc basin likely formed from east-dipping subduction during the development of Ordovician volcanic arcs outboard of Laurentia.Neuilly-sur-Seine, France – January 6, 2021 Geochemical analyses of Cat Square terrane mafic complexes west of the Newton window suggest these bodies represent vestiges of oceanic crust formed in a back-arc basin setting or from both MORB and volcanic-arc sources as characterized by mixed N-MORB and calc-alkaline volcanic-arc signatures. Both granitoids crystallized from the same parent magma the Vale charnockite is an autolith, or early crystallization of the melt, incorporated into the later crystallizing Walker Top Granite. Whole-rock geochemical and isotopic data indicate the Vale charnockite and Walker Top Granite are genetically related and were derived from deep crustal melting of largely Proterozoic-affinity metasediments in an arc environment. Zircon saturation thermometry estimates minimum magmatic temperatures for the granitoids at 800-840⁰ C. Zircon geochronology data indicate crystallization of the Vale charnockite at 366.4 ± 3.1 Ma and the enclosing Walker Top Granite at 356.5 ± 5.3 Ma. Dominant foliation, mineral lineation, and fold-axis orientations suggest north-northwest directed flow occurred in this portion of the Inner Piedmont. The discontinuity of map-scale bodies of metagraywacke, mafic complexes, and amphibolite is attributed to extension during sheath fold formation. Portions of three map-scale sheath folds have been identified by map patterns and orientation of dominant mineral lineations, fold axes, and shear-sense indicators. The Brindle Creek fault has been folded multiple times, resulting in a sinuous outcrop pattern and the formation of the Newton window and smaller Howards Creek window. Structures related to six deformational events have been identified in this portion of the Inner Piedmont. The Brindle Creek fault is a terrane boundary that separates the overlying Siluro-Devonian assemblage of metasedimentary rocks and Devonian-Mississippian anatectic plutons of the Cat Square terrane from the Neoproterozoic(?)-Ordovician metasedimentary and igneous rocks of the Tugaloo terrane. Detailed geologic mapping of portions of the Banoak, Reepsville, Lincolnton West, and Cherryville 7.5-minute quadrangles has confirmed the easternmost exposure of the Brindle Creek fault, which frames the Newton window.
