Evidence for secondary origin of chondrules

Evidence for secondary origin of chondrules Although chondrules have been extensively studied chemically1,2, petrologically3–5 and experimentally6–8, their origin is still not certain. I discuss here whether chondrules were condensed directly from the primitive solar nebula9–11 or were formed from precursory materials by various mechanisms, such as high velocity impact of small bodies12,13, impact on the surface of a parental body14,15 or dust fusion16–18. Investigations of an Antarctic meteorite suggest that chondrules could have formed through melting of pre-existing materials. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

Although chondrules have been extensively studied chemically1,2, petrologically3–5 and experimentally6–8, their origin is still not certain. I discuss here whether chondrules were condensed directly from the primitive solar nebula9–11 or were formed from precursory materials by various mechanisms, such as high velocity impact of small bodies12,13, impact on the surface of a parental body14,15 or dust fusion16–18. Investigations of an Antarctic meteorite suggest that chondrules could have formed through melting of pre-existing materials.
