Chondrules: The canonical and noncanonical views
WEBSep 30, 2016 · Chondrules are igneous rocks found within chondritic meteorites, which are the most abundant meteorites found on Earth. These rocks provide science with the age of the Solar System and contain a record of the first solids to form and evolve in the earliest time period of Solar System formation.
Chondrules - ScienceDirect
WEBJul 30, 2004 · The present paper briefly reviews the main characteristics of chondrules and the relevant properties of chondrites, the leading arguments concerning the origin of chondrules and the nature of their precursor material, and the approaches that presently appear the most promising to unravel this mystery. 2.
The Formation Conditions of Chondrules and Chondrites | Science …
WEBJun 20, 2008 · Chondrules, which are roughly millimeter-sized silicate-rich spherules, dominate the most primitive meteorites, the chondrites. They formed as molten droplets and, judging from their abundances in chondrites, are the products of one of the most energetic processes that operated in the early inner solar system.
CHONDRULES - Annual Reviews
WEBChondrules are ∼1-mm igneous droplets in primitive meteorites, and their abundance suggests widespread melting in the protoplanetary disk. Chondrules with relict unmelted grains or igneous rims record multi111ple melting events.
Chondrules - SpringerLink
WEBApr 19, 2017 · Definition. Chondrules are the most abundant component of chondrite meteorites. The term chondrule comes from the ancient Greek word for the kernel of a grain of wheat, χονδρος (chondros), which chondrules roughly resemble in size and shape. Chondrules are rounded, millimeter, or submillimeter stone particles.
Chondrules: The canonical and noncanonical views
WEBSep 30, 2016 · We examine the evidence for the canonical view of chondrule formation, in which chondrules were free-floating particles in the protoplanetary disk, and the noncanonical view, in which chondrules were the by-products of planetesimal formation.
Physical properties of chondrules in different chondrite groups ...
WEBAug 15, 2010 · Abstract. Chondrite groups (CV, CK, CR) with large average chondrule sizes have low proportions of RP plus C chondrules, high proportions of enveloping compound chondrules, high proportions of chondrules with (thick) igneous rims, and relatively low proportions of type-I chondrules containing sulfide. In contrast, chondrite groups (CM, CO, OC ...
WEBWe examine the evidence for the canonical view of chondrule formation, in which chondrules were free-oating particles in the protoplanetary disk, and the noncanonical view, in which. fl. chondrules were the by-products of planetesimal formation.
