Abstract

Microchemical analysis and x-ray micrographs were performed on thin slices of ice cylinders artificially grown in a tunnel by accretion of supercooled droplets of contaminated water. Characteristic distribution patterns of contaminants were determined for various types of growth, with reference to contaminant transport that can take place in bulk ice. The results, if extended to natural hail, can be very helpful in inferring the environmental growth conditions.
