Petrology of the Unbrecciated Eucrite, Cumulus Hills 04049
Introduction: Eucrite meteorites represent earlyformed (~4.557-4.565 Ga) crustal basalts and basaltic to gabbroic cumulates from the howardite-eucritediogenite (HED) parent body or bodies (e.g., [1]). The HED are commonly thought to originate from the asteroid Vesta (e.g., [2-3]), although O-isotopes for eucrites [4] and diogenites [5] indicate more than one parent body. Approximately 85% of eu...
متن کاملPetrology and Geochemistry of the Nwa 3368 Eucrite
Introduction: A considerable amount of debate exists on the petrogenesis of eucrites, basaltic meteorites believed to have originated on the asteroid 4 Vesta [1]. One school of thought, developed by Stolper [2], suggests that most eucrites are primary partial melts of chondritic material, while another by Mason [3] suggests that eucrites are residual liquids that resulted from fractional crysta...

متن کاملCarbonaceous Chondrite Fragments in the Polymict Eucrite
Introduction: Buchanan et al. [1] and Zolensky et al. [2] described carbonaceous chondrite fragments in a variety of howardites and concluded that the majority are CM2 and CR2 materials. Gounelle et al. [3] also described similar, but very small, fragments in these meteorites. These clasts are important because they represent materials that were in orbital proximity to the HED parent body (4 Ve...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
