Origins of Chondrules in the Metal-rich Carbonaceous Chondrites
Introduction: The metal-rich CH and CB chondrites are among the most primitive (unmetamorphosed, unaltered), but controversial meteorites: both nebular and asteroidal models have been proposed to explain the origins of their components [1-14]. In addition to porphyritic chondrules and rare refractory inclusions, the CHs contain a high abunbance (~20 vol%) of metal and dominant cryptocrystalline...
متن کاملCarbonaceous Nanospheres in Chondrites
Introduction: In the 1960s, prior to the widespread use of TEMs, several papers described rounded, micron-sized organic particles from carbonaceous chondrite (CC) meteorites [1-3]. Some of these particles were hollow. Except for two early TEM studies [4, 5], the rounded structures were essentially neglected until similar material was discovered in the Tagish Lake meteorite [6]. We subsequently ...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولSpectral reflectance properties of carbonaceous chondrites: 3. CR chondrites
Powdered samples of a suite of 14 CR and CR-like chondrites, ranging from petrologic grade 1 to 3, were spectrally characterized over the 0.3–2.5 lm interval as part of a larger study of carbonaceous chondrite reflectance spectra. Spectral analysis was complicated by absorption bands due to Fe oxyhydroxides near 0.9 lm, resulting from terrestrial weathering. This absorption feature masks expect...
