volcaniclastic series from Asia, with the aim of discussing if absolute ages obtained on volcaniclastic rocks can be used directly to date sedimentation. For all these volcaniclastic series, volcanism and sedimentation are reputedly coeval and zircon grains have been dated to obtained depositional ages.

Volcaniclastic Sedimentation and Facies
First-order volcaniclastic facies are generally defined by position of the rock body relative to source within non-marine or marine environments, e.g., proximal, medial and distal facies. These designations are generalized and depend upon the size and volume of deposits.
Volcaniclastic Processes and Deposits in the Deep-Sea
Volcaniclastic Sedimentation in Various Deep-Sea Environments In the first part of this chapter, we presented individual volcanic and volcaniclastic-sedimentation processes in a generic framework.
Sedimentation in Volcanic Settings | Semantic Scholar
We have gained considerable experience with volcaniclastic materials over the past 30 years, but the field has undergone considerable growth in the decade following the 1980 eruption of Mount St. Helens. This eruption resulted in an accelerated research in explosive volcanic products and spurred a renewed interest in volcaniclastic materials as they …
Volcaniclastic Sedimentation in Lacustrine Settings
The unifying theme is that the effects of volcanism on lacustrine sedimentation are diverse and distinctive, and that volcaniclastic lacustrine sediments …

Volcaniclastic sedimentation associated with trachytic …
Dokdo is an erosional remnant of an oceanic intraplate volcano built on the backarc basin floor off the Korean peninsula. Basaltic and trachytic volcaniclastic rocks named the Dongdo and Seodo tuffs, respectively, are sandwiched between the submarine and subaerial volcanic rocks of the island. The Dongdo Tuff consists of polymictic …

The spatial relationship between all the lithofacies provided a four-dimensional reconstruction of the palaeoenvironmental evolution, showing how the original, clastic sedimentation in alluvial/fluvial and lake environments was modified by short-lived volcanic events during three volcanic cycles, and how the environment reacted after the …
Geochemistry and origin of a black mudstone in a volcaniclastic …
Black mudstones in marine volcaniclastic environments have been interpreted both as non-volcanic 'background'sedimentation and as fine grained vitric dust from the waning stages of primary volcanism.
