Survey of ‘Low-Z’ Particles from the Interplanetary Dust Collection in Search of IDPs
Micrometeorites are one of the most common types of extraterrestrial material that fall to the Earth, beside meteorites and interplanetary dust particles (IDPs). All of these materials are known to contain presolar grains that, when studied in the laboratory, provide information about the origin of the solar system and help to constrain models of nucleosynthesis in stars. Recent studies of micr...
متن کاملProduction of Cosmic Dust by Hydrous and Anhydrous Asteroids: Implications for the Production of Interplanetary Dust Particles and Micrometeorites. G
Introduction: In our Solar System the asteroid belt is compositionally zoned, with the asteroids similar in reflection spectrum to the carbonaceopus meteorites dominating the outer-half of the main belt. In the outer-half of the main belt about one-half of the carbonaceous asteroids are hydrous, based on their infrared spectra [1]. The asteroids in the inner-half of the main belt are predominan...
متن کاملPyroxene Whiskers in Cp Interplanetary Dust Particles: Evidence of Vapor Phase Growth
CP micrometeorites are highly porous and fragile interplanetary dust particles (IDP' s) that have chondritic elemental abundances. Among the mineral species found within these particles are pure enstatite crystals, which are unique among the micron-sized constituents of CP IDP' s in that they are euhedral. They exhibit at least three distinct forms, henceforth referred to as rods, ribbons and p...
متن کاملOrdinary Chondrite Micrometeorites from the Koronis Asteroids
Introduction: Micrometeorites (MMs) are large (>25 µm) interplanetary dust particles that survive atmospheric entry to be recovered from the Earth's surface. Amongst those particles that escaped significant heating during atmospheric entry two groups have been identified [1]: (i) fine-grained MMs (fgMMs), which are similar to the fine-grained matrices of hy-drated carbonaceous chondrites (CCs),...
متن کاملA Raman spectroscopic study of organic matter in interplanetary dust particles and meteorites using multiple wavelength laser excitation
Raman spectroscopy was used to investigate insoluble organic matter (IOM) from a range of chondritic meteorites, and a suite of interplanetary dust particles (IDPs). Three monochromatic excitation wavelengths (473 nm, 514 nm, 632 nm) were applied sequentially to assess variations in meteorite and IDP Raman peak parameters (carbon D and G bands) as a function of excitation wavelength (i.e., disp...
