![]() ![]() ![]() The Cannery Formation-Devonian to Early Permian arc-marginal deposits within the Alexander Terrane, Southeastern Alaska In this interval, the Neotethys Ocean opened between India/Arabia and the Cimmerian microcontinents in the east, while widespread lithospheric wrenching and magmatism took place in the west around the Adriatic promontory. The transformation occurred after the cooling of the Variscan mega-suture and lasted Ëœ20 Myr. We therefore review geological evidence from the literature in support of an intra-Pangea dextral megashear system. The transformation from Pangea 'B' to Pangea 'A' took place during the Permian because Late Permian paleomagnetic data allow a Pangea 'A' configuration. We therefore regard the paleomagnetic evidence for an Early Permian Pangea 'B' as robust. We demonstrate, however, by using a dataset consisting entirely of paleomagnetic directions with low inclinations from sampling sites confined to one hemisphere from Gondwana as well as Laurasia that the effects of a zonal octupole field contribution would not explain away the paleomagnetic evidence for Pangea 'B' in the Early Permian. The ultimate option to reject Pangea 'B' is to abandon the geocentric axial dipole hypothesis by introducing a significant non-dipole (zonal octupole) component in the Late Paleozoic time-averaged geomagnetic field. The use of paleomagnetic data strictly from igneous rocks excludes artifacts from sedimentary inclination error as a contributing explanation for Pangea 'B'. New paleomagnetic data from radiometrically dated Early Permian volcanic rocks from parts of Adria that are tectonically coherent with Africa (Gondwana), integrated with published coeval data from Gondwana and Laurasia, again only from igneous rocks, fully support a Pangea 'B' configuration in the Early Permian. The pre-drift Wegenerian model of Pangea is almost universally accepted, but debate exists on its pre-Jurassic configuration since Ted Irving introduced Pangea 'B' by placing Gondwana farther to the east by Ëœ3000 km with respect to Laurasia on the basis of paleomagnetic data.

As part of the Aurora line, the Caliente Aurora only scans flat on the X-axis, so once you have it rigged and focused securely, its good to go just like any other lighting effect. With deep DMX controls and also impressive automatic modes, the Caliente Aurora is perfect for those who want to create big and bold multicolored liquid sky and hot beam effects, even in smaller venues. Following the very successful Caliente RGB700, the Caliente Aurora is brighter, safer, easier to use and more affordable than ever before. This projector requires a variance that can be obtained with the X-Laser EZ Variance Kit (view accessories).Īfter months of development, X-Laser finally has a fully color-mixing Aurora laser: the Caliente Aurora. ![]()
