Summary
Chondrules are among the most abundant components of chondrites, constituting, for example, 55 vol% of CR carbonaceous chondrites and 65–75 vol% of type-3 OC (Table 7.1). Their average apparent diameters range from ~150 µm in CO3 chondrites to ~900 µm in CV3 chondrites; the overall range in diameter is 0.25 µm to ~5 cm. The most common chondrules in all chondrite groups are ferromagnesian objects, rich in olivine and/or low-Ca pyroxene. There are five common textural types of ferromagnesian chondrules.
