CHONDRITE MELTING EXPERIMENTS: CAN ANGRITE LEW87051 BE PRODUCED BY PARTIAL MELTING OF A CV OR CM CHONDRITE? A.J.G Jurewicz
Introduction: LEW2 consists of abundant, coarse subhedral to euhedral olivine crystals (-FOG()90, typical grainsize -0.5mm) set in a fine-grained intergranular groundmass composed primarily of plagioclase, olivine, and Ca-A1 pyroxene [eg. 1,2]. The groundmass clearly represents a crystallized melt [3,4]. McKay et al. [6] proposed that this interstitial groundmass melt was produced by fractional...

متن کاملGraphite and Organic Matter in Abee Enstatite Chondrite
The Ries Crater impact breccia deposits are accessible through a series of boreholes. In 2008, a further hole was cored near the village of Enkingen (SE Ries), accessing the crater breccias at the inner slope of the crystalline ring. The 100 m drill core comprises 21.2 m crater sediment above suevite to )86.24 m and a rather massive impact melt rock to endof-hole [1]. Downhole, the abundance an...
متن کاملA Pristine Amoeboid Olivine Aggregate Protolith from the Vigarano Cv3 Chondrite
Introduction: Amoeboid olivine aggregates (AOA) are irregularly shaped inclusions found within all carbonaceous chondrites except CI [1,2]. Their bulk compositions are intermediate between those of anorthite-rich (Type C) calcium-aluminium rich inclusions and chondrules [2], and consist mostly of fine-grained olivine plus enclosed refractory nodules of spinel, pyroxene, feldspathoids, Fe-Ni met...

تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
