The Eastern Andean Metamorphic Complex at Península La Carmela (48°50’S) consists of quartz-rich metaturbiditic sequences with tectonic slices pillow metabasalt bodies deformed under low-grade metamorphic conditions. Previous and new detrital zircon U–Pb geochronological data from metasandstones indicate a preferred early Carboniferous maximum depositional age the protolith, interpreted younges...

The transition along the strike of Sunda subduction zone, from oceanic in west to continental Australian lithosphere east is envisioned as one canonical examples structural changes that take place within an overriding plate when a wedge enters zone. Yet, along-strike offset trench toward margin represents response opposite predictions numerical models. To understand this paradox, we analyse mor...

Subducted sediment plays a key role in modulating pore pressure and seismic behavior at subduction zones. We investigated the character of incoming sediments to test how basement variations relate along-strike changes within accretionary prism plate boundary conditions Nankai Trough. High-resolution data reveal for first time presence countourite mounded drifts Shikoku Basin. These features hav...

The metamorphosed mafic-ultramafic sequences of the Eastern Andean Metamorphic Complex outcropping in Patagonian Andes are critical to disclose late Paleozoic tectonic evolution southwestern margin Gondwana. In study area, bodies thrusted onto polydeformed metasedimentary rocks and intruded by mid-Carboniferous composite Leones Pluton. metabasalts (mostly tremolite-chlorite schists amphibolites...

The evolution of the Taiwan orogen, an active arc–continent collision zone between North Luzon Arc (NLA) and Eurasian continent, is recorded in arc volcanic sedimentary rocks from Taiyuan retro-foredeep basin Coastal Range, eastern Taiwan. volcanism northern NLA experienced a magmatic culmination at 9–7 Ma cessation 5.3–4.3 Ma, based on new U-Pb zircon ages. Young ages (1.74, 1.58, <1.2 Ma) low...

background: in radiation therapy, the peripheral dose is important when anatomical structures with very low dose tolerances are involved. in this study, the two available calculation algorithms of the varian eclipse 8.6 treatment planning system(tps), the anisotropic analytic algorithm (aaa) and pencil-beam convolution (pbc) was used to compare measured and calculated peripheral dose distributi...

The formation ages and tectonic features of the Bulunkuole Complex (BKC) is critical for understanding geological evolution western section West Kunlun Orogenic Belt (WKOB), they are also metallogenic background Taxkorgan Iron Belt. In this paper, we report new geochemical in situ zircon U–Pb isotopes data most southwestern iron-bearing BKC. petrography sedimentation BKC reveal that main part w...

The Central Asian Orogenic Belt (CAOB) is the world’s largest accretionary orogenic belt, and its formation related to closure of Paleo-Asian Ocean (PAO). However, time style PAO remain controversial. To address these issues, this paper presents zircon U-Pb dating, whole-rock geochemistry Lu-Hf isotope analyses volcanic rocks in Faku-Kaiyuan area on northern margin North China Craton. results s...

Introduction: Wedge filters are used in radiotherapy to modify photon beam and improve dose uniformity in the target volume. Determination of wedge dose distribution is important to improve treatment planning accuracy. The utilization of treatment planning software to obtain dose distribution is not always available. In this work an analytical model has been developed to calcu...

[1] Drilling in the Cascadia accretionary complex enable us to evaluate the contribution of dehydration reactions and gas hydrate dissociation to pore water freshening. The observed freshening with depth and distance from the prism toe is consistent with enhanced conversion of smectite to illite, driven by increase in temperature and age of accreted sediments. Although they contain gas hydrate ...
