The Compositional Structure of the Asteroid Belt

, 2015
The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measurement of physical characterization.

Magnetic Fields Recorded by Chondrules Formed in Nebular Shocks

, 2018
Recent laboratory efforts (Fu et al., 2014) have constrained the remanent magnetizations of chondrules and the magnetic field strengths at which the chondrules were exposed to as they cooled below their Curie points.

Trace elements in the silicate minerals of the Borodino Meteorite (Н5)

Записки Горного института
Major (EPMA) and trace (SIMS) element geochemistry in olivine, low-Са pyroxene and mesostasis from porphyritic and barred chondrules, as well as the pyroxene-olivine aggregate and matrix of equilibrated ordinary Borodino chondrite (Н5) is discussed. No

Chondrule Formation in Bow Shocks around Eccentric Planetary Embryos

, 2012
Recent isotopic studies of Martian meteorites by Dauphas & Pourmond (2011) have established that large (~ 3000 km radius) planetary embryos existed in the solar nebula at the same time that chondrules - millimeter-sized igneous inclusions found in ...
