The respective tectonic effects of back arc spreading and continental collision in Asia are considered either as two independent processes or as closely interrelated. Extrusion tectonics assumes that the opening of the South China Sea and the left-lateral motion along the Red River fault are geometrically linked in a pull-apart manner. This model is not accepted by several workers because the s...

The Java Back-arc Thrust scars the entire back-arc area of Island, but faults’ nature, timing, and activity remain partly elusive. Characterising structure seismogenic (historical earthquakes up to 7 Mw) is a cornerstone evaluate associated geohazards. We focus on western part that reaches megalopolis Jakarta. combine morphotectonic data, seismic reflection, electric resistivity profiles, kinem...

We examine two prominent upper mantle velocity anomalies in the southwest Pacific, the Tonga slab anomaly and the corresponding ov. erlying mantle wedge anomaly, using data collected during a combined land-sea deployment of temporary seismometers. The linear geometry and small interstation spacing of the instruments yield high-resolution data along a cross section of the Tonga subduction zone, ...

The studied serpentinites occur as isolated masses, imbricate slices of variable thicknesses and as small blocks or lenses incorporated in the sedimentary matrix of the mélange. They are thrusted over the associated island arc calc-alkaline metavolcanics and replaced by talccarbonates along shear zones. Lack of thermal effect of the serpentinites upon the enveloping country rocks, as well as th...

Modal analysis of sandstones for conglomerate rich marine basins is useful investigating the provenance types surrounded by plate tectonics. Different kinds siliciclastic rocks are important indicators defining paleogeography and geotectonic conditions sedimentary basin analysis. This paper, which focuses on petrography turbidite systems, one rarest studies characteristics in scientific literat...

U–Pb ages were obtained on single detrital zircon grains separated from six samples of Neoproterozoic and Lower Palaeozoic sedimentary and volcanosedimentary rocks from NW Iberia using the laser ablation microprobe-inductively coupled plasma mass spectrometry (LAM-ICP-MS) method. Precambrian greywackes yielded abundant zircons with Neoproterozoic (800–640 Ma) and Mesoproterozoic (0.9–1.2 Ga) ag...
