Geochemical comparison between Archaean and Proterozoic orthogneisses from the Nagssugtoqidian orogen, West Greenland
In the Palaeoproterozoic Nagssugtoqidian orogen of West Greenland reworked Archaean and juvenile Proterozoic orthogneisses occur side by side and are difficult to differentiate in the field. Archaean gneisses have tonalitic to trondhjemitic compositions with relatively low Al2O3 and Sr, and may have been derived from magmas formed by melting of basaltic or amphibolitic rocks at moderate pressur...
متن کاملProtoliths of the 3.8–3.7 Ga Isua greenstone belt, West Greenland
The Isua greenstone belt (Fig. 1) contains the oldest known, relatively well preserved, metavolcanic and metasedimentary rocks on Earth. The rocks are all deformed and many were substantially altered by metasomatism, but both the deformation and metasomatism were heterogeneous. Transitional stages can be seen from relatively well preserved primary volcanic and sedimentary structures to schists ...

رشد انفجاری تکنولوژی فرصت های آموزشی مهیج و جدیدی را پیش روی فراگیران و آموزش دهندگان گذاشته است. امروزه معلمان برای اینکه در امر آموزش زبان بروز باشند باید روش هایی را اتخاذ نمایند که درآن ها از تکنولوژی جهت کمک در یادگیری زبان دوم و چندم استفاده شده باشد. با در نظر گرفتن تحولاتی که رشته ی آموزش زبان در حال رخ دادن است هم اکنون زمان مناسبی برای ارزشیابی نگرش های موجود نسبت به تکنولوژی های جدید...
15 صفحه اولGeological and Geophysical Reconnaissance for the ONR Geoclutter Program
The common goals of the Geoclutter program are to: (1) understand the acoustic scattering process in shallow water, in order to design physics-based signal processing algorithms to distinguish acoustic returns originating from naturally-occurring features on the world's continental shelves (e.g., iceberg scours, shallow gas accumulations, outcrops of high-amplitude shallow subsurface reflectors...
متن کاملGeological Reconnaissance in the Bridge River Mining Camp
The Bridge River mining camp comprises five former producing mines and numerous currently active mining prospects. The camp may be roughly defined as those properties lying within the Bridge River drainage basin bounded by the Coast plutonic complex on the southwest and the Shulaps ultrabasic complex on the northeast. Reconnaissance work by ministry field parties in 1986 and 1987 covers approxi...
