This video shows the vesiculation of a thin (~100 microns) obsidian wafer from the 2008 eruption at Chaiten volcano, Chile. The obsidian was heated to 875 degrees C in a hot-stage at the facility in the Lancaster Environment Centre, Lancaster University. The growth of individual bubbles can be tracked and rates of growth determined. This is important for understanding the timescales of bubble growth in rhyolite, and decoding the vesiculation history of post-fragmentation pumice clasts and bombs. Some of the results from this research are presented at AGU fall meeting, 2012 and VMSG, 2013. With thanks to co-authors Dr Hugh Tuffen and Dr Mike James, Lancaster University. The song is 'Galaxy' from And Now We're Evens 3rd album 'Fall for you' [ Ссылка ]
