Microseismicity of the ultraslow-spreading Gakkel ridge, Arctic Ocean: a pilot study
S U M M A R Y The active mid-ocean ridge of the Arctic Ocean, named Gakkel ridge, is the slowest spreading ridge of the global system of mid-oceanic ridges with full spreading rates declining from about 12.5 to 6 mm yr−1 from west to east. Geological models of seafloor spreading predict a decreasing intensity of magmatic processes with decreasing spreading rate. In summer 2001, the multidiscipl...
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
15 صفحه اولConstraints on shallow mantle viscosity from morphology and deformation of fast‐spreading ridges
[1] We show that the morphology and the deformation of a fast spreading ridge constrain shallow upper mantle viscosity. A fast spreading center is simulated in a numerical model that couples tectonic deformation due to plate spreading and periodic dike emplacements. The amount of magma intruded into dikes or extruded is enough to make a 7 km thick crust and the axial lithosphere is fixed at ∼2 ...
متن کاملSlow Spreading Ridges of the Indian Ocean: An Overview of Marine Geophysical Investigations
Sparse and non-availability of high resolution geophysical data hindered the delineation of accurate morphology, structural configuration, tectonism and spreading history of Carlsberg Ridge (CR) and Central Indian Ridges (CIR) in the Indian Ocean between Owen fracture zone at about 10N, and the Rodriguez Triple Junction at ~25S. Analysis of available multibeam bathymetry, magnetic, gravity, sea...
متن کاملthe effect of the utilization of electronic dictionaries on depth and breadth of vocabulary knowledge: a case of iranian efl learners
مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...
