In recent years, a rapidly expanding database, especially in sensitive high-resolution ion microprobe (SHRIMP) geochronology, has led to signifi cant advances in understanding of the Precambrian tectonic evolution of the Grenville Province, including its Adirondack outlier, and the Mesoproterozoic inliers of the Appalachians. Based upon this information, we review the geochronology and tectonic...

Explosion metal welding is high-speed angle oblique collision of two or more metal plates caused by detonation. The metal is joined – welded under high dynamic pressure creating by plastic deformation the waves on the bond interface, accompanied by local adiabatic heating 1 . The explosive metal cladding process can be divided into three stages: a) generation of explosion energy through the det...

Most subduction zones on Earth are oblique, i.e., the angle between plate convergence vector and trench notably differs from 90°. Therefore, modeling understanding strain partitioning in forearc, development of extensional basins back-arc region diachronous transition to collision require a 3D approach. Here, we assess how oblique oceanic subsequent associated mantle flow around subducted litho...

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...

[1] Using a high-speed video camera, we studied oblique collisions of lapilli-size pumice cylinders (with no rotation before impact) on flat pumice targets. Our results show that the rebound angle, the ratios of the components of velocities and the energy loss vary with the impact angle. In particular, in collisions with an average yaw angle approximately equal to zero, we observed relatively l...

The evolution of the Caribbean plate has resulted in formation volcanic arcs, Large Igneous Province (CLIP) and micro-plates across boundary zones. northern with North American been particularly segmented transition from oblique subduction to collision moving east west. However, there are few constraints on seismic structure upper mantle boundary. Here we use S-to-P receiver functions map veloc...
