DOI: 10.1002/esp.4284
Abstract: The age of past lava flows is crucial information for evaluating the hazards and risks posed by effusive volcanoes, but traditional dating methods are expensive and time-consuming. This study proposes an alternative statistical dating method… read more here.

DOI: 10.1007/s00445-017-1187-8
Abstract: The impact of Holocene eruptive events from hot spots like Iceland may have had significant global implications; thus, dating and knowledge of past eruptions chronology is important. However, at high-latitude volcanic islands, the paucity of… read more here.

DOI: 10.1007/s12040-019-1208-4
Abstract: The Deccan trap basaltic lava flows host a plethora of secondary minerals, notably zeolites, quartz and calcite. These minerals occupy the vesicles and cavities that are formed during the solidification of the lava flows. Much… read more here.

DOI: 10.1016/j.aquabot.2017.10.005
Abstract: Recent volcanic lava flows extending into the ocean represent an ideal opportunity to study the long-term successional development of marine floral assemblages on the bare new substratum. We describe the floral assemblages of nine lava… read more here.

DOI: 10.1016/j.chemgeo.2019.119355
Abstract: Abstract The geomagnetic field prevents a portion of incoming cosmic rays from reaching Earth’s atmosphere. During magnetic reversals and excursions, the field strength can decrease by up to 90% relative to the modern-day value. During… read more here.
