The Pieniny klippen belt: its tectonic structure and evolution

Role of supra-subduction zone ophiolites in the tectonic evolution of the southeastern Zagros Orogenic Belt, Iran

Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were u...

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

Mesozoic Basin Development and Tectonic Evolution of the Dabieshan Orogenic Belt, Central China

Tectonic and Volcanic Evolution of Dark Terrain and Its Implications for the Internal Structure and Evolution of Ganymede

Furrows in ancient dark terrain on Ganymede form three systems that are each hemispheric or greater in scale. The oldest of the systems, designated system ]II, is dominated by approximately concentric troughs centered on about 60øN,50øW. System I, in the anti-Jovian hemisphere, contains concentric and subradial furrows arrayed around a large, degraded palimpsest centered at 15øS,165øW. Furrows ...

Tectonic evolution of the early Mesozoic blueschist-bearing Qiangtang metamorphic belt, central Tibet

[1] A >500-km-long east-west trending metamorphic belt in the Qiangtang terrane of central Tibet consists of tectonic melange that occurs in the footwalls of Late Triassic–Early Jurassic domal low-angle normal faults. The melange is comprised of a strongly deformed matrix of metasedimentary and mafic schists that encloses lesser-deformed blocks of metabasites, Carboniferous–Triassic metasedimen...
