Poster presented at ToScA 2015 (Tomography for Scientific Advancement conference) held at Manchester University.

The poster outlines preliminary studies applying x-ray microtomography to the analysis of volcanic ash horizons preserved in lake sediments. This work has application to the field of tephrochronology, the study of volcanic ash (tephra) to determine the age, either relative or absolute, of sedimentary deposits.

This work relates to a larger project investigating the effect of sedimentary reworking on the position of the tephra isochrons.

This is a Swansea University funded project using equipment at Swansea's AIM facility.

This poster has a "lightening" talk associated with it found in the links below.
