Active microplate boundaries in ocean-continent subduction zones may induce deformation of the overlying plate and spatial or geochemical variations in the volcanic arc. We discuss two modern cases. The first is the South Gorda-Juan de Fuca plate boundary in the Cascadia subduction zone, where there is little or no effect on the overriding plate and the oceanic plate takes up much of the deform...

Strain patterns within the forearc at a convergent margin adjacent to a passing fault-fault-trench triple junction show a systematic evolution. We describe late Neogene and Quaternary deformation in northern coastal California in the last 3 m.y. associated with the migration of the Mendocino triple junction. Deformation in the North American forearc near Humbolt Bay consists of a 30-km-wide zon...

The genetic contribution to dizygotic (DZ) twinning was investigated using 6,596 twin pairs from the Australian Twin Registry who provided information on other twins in their families. Responses were classified by the zygosity (DZ; monozygotic [MZ]) of the proband twins and by the relationship and zygosity of related twins. MZ probands and MZ twins reported by DZ probands were used as controls ...

The Shah-Kuh granitoid has intruded in the Triassic–Jurassic, pelitic and psammitic low-grade metamorphic rocks of the NE LutBlock, in Central Iran. Cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. Deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. Therela...

Tectonic interpretations of arc remnants in the Himalayan orogen remain uncertain, despite their important implications for overall convergence history between India and Eurasia. Provenance results from deep-water volcaniclastic rocks Indus Suture Zone Ladakh provide new constraints on Mesozoic tectonic evolution Dras Kohistan-Ladakh arcs. Detrital zircon (DZ) U-Pb ages whole-rock geochemistry ...

The ~30-km-long surface ruptures associated with the Mw 7.0 (Mj 7.3) earthquake at 01:25 JST on April 16 in Kumamoto Prefecture appeared along the previously mapped ~100-km-long active fault called the Futagawa-Hinagu fault zone (FHFZ). The surface ruptures appeared to have extended further west out of the main FHFZ into the Kumamoto Plain. Although InSAR analysis by Geospatial Information Auth...

1. The effects of the benzodiazepine receptor agonist, diazepam (DZ), and the inverse agonist, methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (DMCM), on gamma-aminobutyric acid (GABAA) receptor single channel currents were characterized. Outside-out patches were obtained from somata of cultured mouse spinal cord neurones and voltage clamped at -75 mV (ECl = 0 mV). 2. GABA (2 microM) ...

Small-angle neutron scattering measurements of deformed single-crystal copper have been performed over a wave-vector transfer range of 0.0655 <__ Q < 1.32 nm l . The measurements included four samples deformed in compression at room temperature along the [110] direction to 6.8, 15.6, 35.0 and 54.3% reduction in thickness and an undeformed reference sample. The response of the reference sample f...
