BACKGROUND The submental artery island flap is a reliable reconstructive option for lower face defects. Advantages of this flap include suppleness of tissue, excellent color and texture match to facial skin, a wide arc of rotation, prominent blood supply, and a well-hidden donor site scar. METHODS This article describes a 61-year-old man with eccrine carcinoma of the chin necessitating extens...

Abstract Eastern Indonesia has a complicated structure due to the collision of Eurasian Plate, Pacific Indo-Australian and Philippine creating an active seismic zone. The Banda - Seram segment eastern comprises subduction, rollback, detachment, slab tear, back-arc thrust, volcanic arc. Sri Widiyantoro did previous study in utilizing tomography methods detect upper mantle 180-degree curved trans...

Various evidence, including size and volume of the Siberian Traps, timing and duration of eruptions, paleotectonic and paleogeographic reconstructions, lithospheric structure, heat flow, trace element and radiogenic isotope compositions of lava are reviewed in this chapter. The major evidence may be summarized as follows. The Siberian Traps erupted in a number of brief volcanic events from the ...

Volcanic activity at convergent plate margins is localized along lineaments of active volcanoes that focus rising magma generated within the mantle below. In many arcs worldwide, particularly continental arcs, the volcanic front migrates away from the interface of subduction (the trench) over millions of years, reflecting coevolving surface forcing, tectonics, crustal magma transport, and mantl...
