Silicon Isotope Evidence Against an Enstatite Chondrite Earth

open access: yesScience, 2012
Building Blocks of Earth Earth formed from an explosive and energetic series of collisions that accreted material over millions of years. Comparisons between rocks from Earth's interior and more primitive extraterrestrial samples can help tease apart the composition of Earth's starting material; however, discrepancies between the

The Parsa enstatite chondrite

open access: yesMeteoritics, 1980
Two meteoritic stones weighing roughly 600 and 200 g fell on 14 April 1942 near Parsa, Bihar, India. The meteorite is a high‐Fe (EH) enstatite chondrite on the basis of its large abundance of chondrules, its low concentrations of refractory elements, the Si content of its metal (25–30 mg/g), and its enstatite composition Mg0.975Ca0.007Fe0.018. The high

Lewis Cliff 87223, an anomalous enstatite chondrite and the diversity of enstatite chondrites

Meteoritics & Planetary Science, 2023
We studied a thin section of Lewis Cliff (LEW) 87223, an unusual EL3‐related, enstatite chondrite (EC) that has primary and secondary features not observed in other ECs. We studied its metal‐rich nodules, possible shock features, and chondrules, eight of

The Unequilibrated Enstatite Chondrites

Chemie Der Erde, 2012
Abstract The enstatite chondrites formed under highly reducing (and/or sulfidizing) conditions as indicated by their mineral assemblages and compositions, which are sharply different from those of other chondrite groups. Enstatite is the major silicate mineral.
