Highly N-enriched Chondritic Clasts in the Cb/ch-like Isheyevo Meteorite
L. Bonal*, G.R. Huss, A.N. Krot, and K. Nagashima, HIGP/SOEST, University of Hawai‘i at Mānoa, Honolulu, HI 96822, USA. *[email protected] Metal-rich (CB, CH, CB/CH-like) carbonaceous chondrites exhibit several anomalous characteristics not observed in other chondrite groups, including (i) a nearly complete absence of interchondrule fine-grained matrix, and (ii) the highest whole-rock enri...
متن کاملHydrogen Isotopic Composition of N-rich Clasts in the Cb/ch-like Chondrite Isheyevo
Metal-rich (CB, CH, Isheyevo) carbonaceous chondrites are characterized by the highest whole-rock enrichments in 15 N (δ 15 N up to +1500‰) and nearly complete absence of interchondrule fine-grained matrix [e.g., 1]. The fine-grained material occurs mainly as chondritic clasts, which experienced low-temperature aqueous alteration on their initial parent body(ies) and were subsequently accreted ...
متن کاملHighly N-enriched Chondritic Clasts in the Isheyevo (ch/cb) Meteorite: Tem Analyses
Introduction: Isheyevo, a metal-rich CH/CB-like meteorite, shows whole-rock δ 15 N enrichment up to ~+1500‰ [1]. Bonal et al. discovered rare chondritic clasts in Isheyevo containing mafic silicates, large bulk 15 N enrichments (δ 15 N from +1000 to 1300‰) and µm-sized " hotspots " with δ 15 N approaching +5000‰ [2,3]. The source of these high 15 N enrichments, whether due to molecular cloud, n...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
A Hierarchical 3d Reconstruction Approach for Documenting Complex Heritage Sites
Digitally reconstructing a large and complex heritage site, for example a medieval castle, for documentation and virtual reality simulation is a challenging task that requires combining models created by different data sets from several digitisation technologies. Our approach resembles the level of detail (LOD) concept used in visualization of complex models. Our procedure is hierarchical by th...
