Cosmogenic neon in grains separated from individual chondrules: Evidence of precompaction exposure in chondrules
Neon was measured in 39 individual olivine (or olivine-rich) grains separated from individual chondrules from Dhajala, Bjurböle, Chainpur, Murchison, and Parsa chondrites with spallation-produced Ne the result of interaction of energetic particle irradiation. The apparent Ne cosmic ray exposure (CRE) ages of most grains are similar to those of the matrix with the exception of three grains from ...
متن کاملOn the spectra of some matrices derived from two quadratic matrices
begin{abstract} The relations between the spectrum of the matrix $Q+R$ and the spectra of the matrices $(gamma + delta)Q+(alpha + beta)R-QR-RQ$, $QR-RQ$, $alpha beta R-QRQ$, $alpha RQR-(QR)^{2}$, and $beta R-QR$ have been given on condition that the matrix $Q+R$ is diagonalizable, where $Q$, $R$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of ord...

متن کاملOxygen Isotopes of Al-rich Chondrules from Unequilibrated Ordinary Chondrites
Al-rich chondrules (ARCs) are a rare constituent of chondrites. They have relatively high bulk Al20 3 content(> 10 wt%), which is due to the presence of Al-rich phases, such as plagioclase, spinel, Al-rich glass etc. [1]. ARCs share some chemical and petrologic characteristics with Ca, Al-rich inclusions (CAis), and may represent a genetic link between ferromagnesian chondrules and CAis. Twelve...
