Impaction and non-eruption of teeth is a common problem encountered in orthodontics and many techniques have been proposed for the management of this condition. It has been advocated that a system utilizing magnets would supply a continuous, directionally sensitive, extrusive force, through closed mucosa and thus provide not only a physiological sound basis for successful treatment, but also re...

Abstract Late brittle extension is a common feature in orogenic belts, and its role mountain building processes still the subject of debate. Its timing relationship with crustal thickening, topography, basin infill, rock exhumation are key importance determining whether it major factor development or merely causes near-surface secondary effects. We examined this question relation to active arc-...

Abstract Volcanoes switching from quiescence to eruption shortly after catastrophic earthquakes have raised interest for volcanic triggering and the influence of on activity. Its already active systems especially at open-vent volcanoes is more difficult apprehend. A number recent observations suggest an tectonic Popocatépetl’s activity, importance which remains unknown. To further investigate t...

A variety of structures results from the interplay evolving far-field forces, plate kinematics, and magmatic activity during continental break-up. The east Limpopo transform margin, offshore northern Mozambique, formed as Africa Antarctica separated mid-Jurassic period break-up Gondwana supercontinent. nature crust onshore has been discussed for decades in an effort to resolve issues with kinem...

Mare domes, small shield volcanoes typically <∼30 km diameter, are part of the spectrum lunar volcanic features that characterize extrusive basalt deposits. We used new spacecraft data to document these in Tranquillitatis, among oldest maria and site commonly interpreted as an ancient degraded non-mascon impact basin. found 283 known suspected mare with majority (n = 229) concentrated on a broa...

The Jurassic ophiolites in the Northern Apennines and Western Alps represent fossil mid-ocean ridge (MOR) oceanic lithosphere that formed Mesozoic Ligurian-Piedmont Ocean Basin (LPOB). Their sedimentary covers include chaotic rock units containing ophiolite-derived material. processes of formation lithostratigraphic position these remain a matter debate, unlike their counterparts Apennines. Thi...

Magnetic anomaly variations near mid-ocean ridge spreading centers are sensitive to a variety of crustal accretionary processes as well geomagnetic field when the crust forms. We collected near-bottom vector magnetic data during series 21 autonomous underwater vehicle Sentry dives 9°50′N on East Pacific Rise (EPR) covering ∼26 km along-axis. These document 2–3 wide axial high that is commonly o...

The Neoproterozoic rocks of the Nakora Ring Complex (NRC) consist three phases (Extrusive, Intrusive and Dyke) that are based on detailed geological mapping (contact relationship, mode occurrence, position xenolith, flows, dykes veins) their stratigraphic position. NRC consists mainly acid volcanic besides minor amount basic with intermediate calc-alkaline to tholeiitic affinities occurs in for...
