image: Researchers sampling Kaharoa rhyolitic domes (lava flows) in this study. The rhyolite dome material (most of the field of view) is overlain by layers of basaltic tephra from the 1886 deposit (reddish, layered deposits at top of photo). The 1886 fissure exposed the interior of the lava domes, making them accessible to sampling. This material relates to a paper that appeared in the June 16, 2017, issue of Science, published by AAAS. The paper, by A.E. Rubin at University of California, Davis in Davis, CA, and colleagues was titled, 'Rapid cooling and cold storage in a silicic magma reservoir recorded in individual crystals.' view more
