The Kangareh gabbro body is located in south of the Kurdistan Povince and southwest of the Qorveh area. The area belongs to the Sanandaj-Sirjan zone. Tectonic evolutions during Mezozoic and magmatism, due to subduction of the Neo-Tethys oceanic lithosphere beneath the Iran microplate, led to formation of various igneous bodies in this area. Chemical analysis of pyroxene minerals and whole rock ...
We present a multidisciplinary study of morphology, stratigraphy, sedimentology, tectonic structure, and physical oceanography to report that the complex geomorphology Palomares continental margin adjacent Algerian abyssal plain (i.e., Gulf Vera, Western Mediterranean), is result sedimentary response Aguilas Arc indentation in Eurasian–Africa plate collision. The imprinted on basement with elon...
Abstract Continental-scale recycling of detrital zircon (DZ) grains and associated sediment across North American is not well understood. We trace a through line following the DZ proxy for detritus originally sourced from Grenville Appalachian orogens. This paper lays out an antecedent framework one greatest sedimentation episodes Phanerozoic: initial dispersal Appalachian- Grenville-age to wes...
Cretaceous volcano-sedimentary basins and successions in the Korean Peninsula are located along NE-SW- NNE-SSW-trending sinistral strike–slip fault systems. Soft-sediment deformation structures (SSDS) of lacustrine sedimentary strata occur Wido, Buan, Haenam areas southwestern Peninsula. In this study, systematic geological, geochronological, geochemical investigations volcanic-sedimentary were...
The shelf areas around the Antarctic Continent are locations of dense water formation; part of these water masses ventilate the adjacent deep ocean basins and enter the global thermohaline circulation. This paper takes a look at regional differences of shelf sea–deep ocean exchange in high southern latitudes (mainly between the Weddell and Ross Seas), highlights a few physical mechanisms potent...
Decomposition of dissolved organic carbon, nitrogen and phosphorus (DOC, DON, DOP) was measured for surface and bottom waters of the middle Atlantic bight (MAB) and deep slope water adjacent to the MAB on two occasions in March and August 1996. We used standard bottle incubation techniques to measure the decrease in dissolved organic matter (DOM) concentrations over a 180-day interval. Generall...
