(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

Authigenic ferrimagnetic iron sulfides, essentially greigite (Fe 3 S 4 ), are commonly found in gas hydrate-bearing marine sediments of active accretionary prisms. Greigite is a by-product, either intracellular or extracellular, microbial activity, and therefore provides good indication processes which closely related to the occurrence hydrate. A high-resolution rock magnetic study was conducte...

Fault-controlled mixed siliciclastic-carbonate-evaporite depositional systems exhibit distinct sensitivity to tectonic and eustatic controls that are expressed in the sedimentary architecture. In Upper Carboniferous Billefjorden Trough (Svalbard, Norway), up 2,000 m of a warm arid climate syn-rift basin fill comprises such systems, documented this study with traditional field techniques support...

We use the L-band Advanced Land Observing Satellite (ALOS) and C-band Envisat interferometric synthetic aperture data and campaign GPS observations to study the postseismic deformation due to the 2005 magnitude 7.6 Kashmir (Pakistan) earthquake that occurred in the northwestern Himalaya. Envisat data are available from both the descending and ascending orbits and span a time period of~4.5 years...

First-order (transform) and second-order ridge-axis discontinuities create a fundamental segmentation of the lithosphere along mid-ocean ridges, and in slow spreading crust they commonly are associated with exposure of subvolcanic rust and upper mantle. We analyzed available morphological, gravity, and rock sample data from the Atlantic Ocean to determine whether consistent structural patems oc...

Timing of surface uplift of the Tibetan Plateau has received much attention because of proposed links between high topography and change in regional and global climate, southern Asian paleoecology, and ocean chemistry (Quade et al., 1989; Edmond, 1992; Prell and Kutzbach, 1992; Raymo and Ruddiman, 1992; Molnar et al., 1993; Derry and France-Lanord, 1996). However, the actual vintage of high ele...
