Abstract
⺠Various mineral microspherules have been identified in coal. ⺠Most microspherules, such as pyrite, glauconite, hematite, calcium oxalate and allophane, are colloidal in origin. ⺠Some microspherules, such as garnet and sphene, are mainly derived from sediment-source region. ⺠A few microspherules are probably from volcanogenic sources or from cosmic dust. ⺠Fine-grained minerals may play an important role in the formation of ultrafine fly ash particles.
