Webated with the presence of olivine and pyroxene. In clasts with these phases, Ca phosphate is rare, suggesting that Ca phosphate was formed by aqueous alteration of Fe,Ni phosphide and Ca-bearing phases. As noted in [3], there is the rare presence of olivine-rich clasts that appear to be the least altered clasts in Ryugu samples. WebOlivine is one of the most common minerals in the earth, and is a major rock forming mineral. Despite this, good specimens and large crystals are uncommon and sought after. Only few localities yield large examples of this mineral, although small and microscopic grains are found worldwide. Olivine is also found in meteorites, and large grains ...
