pyroclastic fall deposit

GLOSSARY OF VOLCANIC TERMS
Volcaniclastic (pyroclastic) deposits formed from the rain-out of clasts through the atmosphere from an eruption jet and/or plume during an explosive eruption (Houghton et al., 2000, p. 555). Fall deposits typically exhibit mantle bedding, are well sorted, and commonly show well-developed planar stratification (Cas and Wright, 1987, p. 95-96).
