The Irony of Iron – Life'S Major Trace Element

Modeling Major and Trace Element Chemistry of Zoned Metal Grains

Introduction: The compositional variations [1 and references therein] in the zoned metal grains from the CH and CB chondrites are generally interpreted as unequivocal evidence for their condensation from a parcel of H 2-rich gas with solar or somewhat increased dust/gas (D/G) ratios [2,3]. Although different origins of such gas are discussed [e.g., 4-7], its high enrichment in H 2 [8] and low a...

Major and trace element composition of copiapite-group minerals and coexisting water from the Richmond mine, Iron Mountain, California

Copiapite-group minerals of the general formula AR4(SO4)6(OH)2d nH2O, where A is predominantly Mg, Fe , or 0.67Al, R is predominantly Fe, and n is typically 20, are among several secondary hydrous Fe sulfates occurring in the inactive mine workings of the massive sulfide deposit at Iron Mountain, CA, a USEPA Superfund site that produces extremely acidic drainage. Samples of copiapite-group mine...

Trace Element Microanalysis in Iron Meteorites by Laser Ablation ICPMS.

A laser ablation microanalysis system has been developed that can analyze trace elements with a sensitivity in the ppb range, using a CETAC LSX-200 laser ablation system with a Finnigan Element. This capability has been applied to a set of iron meteorites to demonstrate the laser microprobe's analytical capability for the determination of platinum group elements (PGEs) with a spatial resolution...

Canadian Precambrian Iron-formations: Ages and Trace Element Compositions

the trace of translators ideology in literary translations: a case study of persian translation of the scaret letter

رساله ی حاضر تلاشی است برای بررسی مبحث ایدئولوژی در ترجمه ادبی و تاثیرات آن بر کار مترجم، اعم از گزینش واژگان و ساختارهای دستوری؛ با تمرکز بر تحلیل انتقادی گفتمان در متن مبدأ و متن مقصد، که در این رساله متن مبدأ رمان داغ ننگ اثر ناتانیل هاوثورن و ترجمه فارسی سیمین دانشور به عنوان متن مقصد مورد بررسی قرار گرفته است. تجزیه و تحلیل رمان های مورد نظر به طور عمده بر اساس مدل پیشنهادی فرحزاد(2007) بر...
