#In basin & tectonic analyses, volcanic sediments can be treated methodologically like non vplcanic sediments, but the close association of tectonism & volcanism provides an added dimension to the analytical importance of volcaniclastic sediments [p.1]

1] volcanic rocks
2] widespread ash layer
3] dissemination ash in sediments
4] alteration products

1] size, freq & loct of past eruptions
2] the composition of the erupted magma
3] amounts of climatologiccaly important volatiles released (CO2, SO2. HCl)
#Historic eruptions (up to about 50km3 of erupted magma, e.g., Tambora AD 1815 that produced idespread clouds of sulfuric acid aerosols are associated w/ small (<1degree C) coolings on a hemispheric to global scale that last from 1 to 3 years after the eruptions
