Geochemical analyses and images of tephra and other particulate samples from the Law Dome Ice Core
Entry ID: Law_Dome_Tephra

[ Update this Record ]

Summary
Abstract: This data set contains geochemical information and backscattered electron
images of particulate material sampled from the Law Dome ice core. Some of
this material is volcanic ash, and other samples contain terrestrial dust
consisting mainly of quartz, feldspar, mica and clay minerals. The geochemical
information provided is based on electron microprobe analysis polished samples
of particulate material.
