摘要:Abstract(#br)We have applied the unspiked K-Ar and the 40 Ar/ 39 Ar methods to samples precisely collected and localised, on both Central Indian Ridge flanks, to test their effectiveness and reliability when applied to the dating of recent (i.e. less than 1 Ma) MORBs. Twenty...

摘要:Abstract(#br)The Blake excursion was among the first recognized with directional and intensity behavior known mainly from marine sediment and Chinese loess. Age estimates for the directional shifts in sediments are poorly constrained to about 118−100 ka, i.e., at the marine ...

摘要:Abstract(#br)Reversals and excursions of Earth's geomagnetic field create marker horizons that are readily detected in sedimentary and volcanic rocks worldwide. An accurate and precise chronology of these geomagnetic field instabilities is fundamental to understanding several asp...

摘要:Abstract(#br)Rhyolitic magmas have rarely erupted during historical times, thus we have a poor record of the signals of unrest that precede them. The Laguna del Maule volcanic field (LdM), Chile, is in the midst of a decade-long episode of unrest including surface inflation at mo...

摘要:Abstract(#br)The Andean Southern Volcanic Zone comprises > 30 active arc front volcanoes that grew over periods of hundreds of thousands of years. Quantifying the rates at which these volcanoes grow is key to appreciating geological hazards, clarifying petrologic evolution, ...

摘要:Abstract(#br)The June, 6, 1912 eruption of more than 13 km 3 of dense rock equivalent (DRE) magma at Novarupta vent, Alaska was the largest of the 20th century. It ejected >7 km 3 of rhyolite, ∼1.3 km 3 of andesite and ∼4.6 km 3 of dacite. Early ideas about the origin of pyr...

摘要:Abstract(#br)The Réunion event is one of the earliest recognized periods of normal polarity within the reversed Matuyama chron. Named for the site at which it was first discovered on Réunion Island, it has since purportedly been found globally in both volcanic rocks and sedi...
