A New Gekko from Sibuyan Island, Central Philippines
We describe a new species of lizard in the genus Gekko from Sibuyan Island in the Romblon Island group of the central Philippines. Although the new species is diagnosed from other Philippine Gekko by body size and shape, coloration, and multiple characteristics of external morphology, additional support for the recognition of the Sibuyan Gekko population as a distinct evolutionary lineage is ga...
متن کاملUltra-calcic Magmas Generated from Ca- depleted Mantle: an Experimental Study on the Origin of Ankaramites
Ultra-calcic ankaramitic magmas or melt inclusions are ubiquitous in arc, ocean-island and mid-ocean ridge settings. They are primitive in character (XMg 4 0 65) and have high CaO contents (414 wt %) and CaO/Al2O3 (41 1). Experiments on an ankaramite from Epi, Vanuatu arc, demonstrate that its liquidus surface has only clinopyroxene at pressures of 15 and 20 kbar, with XCO2 in the volatile comp...
متن کاملPerformance Evaluation and Comparison of Ultra-thin Bulk (UTB), Partially Depleted and Fully Depleted SOI MOSFET using Silvaco TCAD Tool
Device miniaturization is an important part of VLSI design, which refers to reduction in dimension of device by keeping all other characteristic constant. As technology node is moving in submicron region, the performance of the device degrades due to short channel effects and narrow channel effects. The key issues due to these effects are draininduced-barrier– lowering (DIBL), leakage current, ...
متن کاملUltra-depleted, shallow cratonic mantle beneath West Greenland: dunitic xenoliths from Ubekendt Ejland
Dunitic xenoliths from late Palaeogene, alkaline basalt flows on Ubekendt Ejland, West Greenland contain olivine with 100 · Mg/(Mg + Fe), or Mg#, between 92.0 and 93.7. Orthopyroxene has very low Al2O3 and CaO contents (0.024–1.639 and 0.062–0.275 wt%, respectively). Spinel has 100 · Cr/ (Cr + Al), or Cr#, between 46.98 and 95.67. Clinopyroxene is absent. The osmium isotopic composition of oliv...
متن کاملBoninite-like intraplate magmas from Manihiki Plateau require ultra-depleted and enriched source components
The Ontong Java and Manihiki oceanic plateaus are believed to have formed through high-degree melting of a mantle plume head. Boninite-like, low-Ti basement rocks at Manihiki, however, imply a more complex magma genesis compared with Ontong Java basement lavas that can be generated by ∼30% melting of a primitive mantle source. Here we show that the trace element and isotope compositions of low-...
