Mössbauer Spectroscopy of Olivines across the Mg-fe Solid Solution
Introduction: Olivine is a major mineral component on terrestrial planetary surfaces and, therefore, it is important to understand its spectroscopic characteristics at all wavelengths. Here we present a detailed Mössbauer study of ten synthetic olivines in the fayalite-forsterite series in the interest of answering the following questions: 1. What are the Mössbauer parameters corresponding to t...
متن کاملIdentification of Feo-rich Relict Olivines in Type Iia Chondrules Using Fe-mn
Introduction: Relict grains (i.e., grains that did not crystallize in situ from the host chondrule melt) provide a real physical record of chondrule precursor grains. Most relicts appear to be derived from previous generations of chondrules and hence represent evidence for recycling of material in the chondrule forming region(s). [1] estimated that at least 15% of chon-drules contain material t...
متن کاملFe/Mg-Fe/Mn SYSTEMATICS OF CHONDRULES AND THEIR HOST CHONDRITES: CLUES FOR THEIR
Introduction: Composition of chondrites on Fe-MgMn diagram show distinct patterns that result from nebular processes like volatility-controlled Mn-Mg fractionation, metal/silicate fractionation under reducing conditions and subsequent oxidation leading to variations in FeO/MgO ratio [1]. As chondrules are the major constituent of chondrites (except CI) their effect on bulk chemical compositions...
