Bubble Sizes in Vesicular Basalt

Jason Turflinger and Carl Drummond

Indiana University - Purdue University Department of Geosciences


Students analyze vertical changes in vesicle size-frequency distributions over small distances. They cut and prepare a hand sample of vesicular basalt, creating polished parallel to horizontal slabs that can then be treated with acetate peels to produce images for digital analysis and interpretation.
