Role of syn-eruptive plagioclase disequilibrium crystallization in basaltic magma ascent dynamics
Timescales of magma ascent in conduit models are typically assumed to be much longer than crystallization and gas exsolution for basaltic eruptions. However, it is now recognized that basaltic magmas may rise fast enough for disequilibrium processes to play a key role on the ascent dynamics. The quantification of the characteristic times for crystallization and exsolution processes are fundamen...
متن کاملCrystallization Stages of the BishopTuff Magma Body Recorded in Crystal Textures in Pumice Clasts
The BishopTuff is a giant silicic ignimbrite erupted at 0·76Ma in eastern California, USA. Five pumice clasts from the late-erupted Bishop Tuff (Aeolian Buttes) were studied in an effort to better understand the preand syn-eruptive history of the Bishop magma body and place constraints on the timescales of its existence. This study complements and expands on a previous study that focused on ear...
متن کاملAge and stratigraphic relationships of pre- and syn-rift volcanic deposits in the northern Puertecitos Volcanic Province, Baja California, Mexico
Ž . Geologic mapping of volcanic strata of the northern Puertecitos Volcanic Province PVP in northeastern Baja California, Mexico, performed in conjunction with ArrAr analysis and petrochemical study, documents the Miocene geologic history of a well-preserved volcanic succession within the northern Sierra Santa Isabel and its relationship to the evolving Pacific–North America plate boundary. Su...
متن کاملBiodiversity during the Deccan volcanic eruptive episode
This paper gives a detailed overview of biotic assemblages recovered from the Deccan trap intercalated sedimentary sequences (infraand intertrappean beds) of peninsular India as a result of extensive research done during the last 20 years. The infraand intertrappean beds contain remnants of Gondwanan forms such as myobatrachinae frogs, pelomedusid turtles, dinosaurs (i.e. titanosaurids and abel...
