2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 From: Stephan Kolzenburg <skolzenburg@xxxxxxxxxxxxxx> 2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 Dear Colleagues and Friends, We would like to invite you to join us on a field trip to the intrusive complexes and volcanics of coastal Maine. The trip will take place from the* 18th to the 23rd of July 2019*, immediately following the IUGG general assembly 2019. The trip outline follows below and can also be found here: http://iugg2019montreal.com/fieldtrips.html Registration for the field trip will open soon and *participation in the IUGG general assembly is not mandatory* to join the field trip. The price for the six day field trip is 1.930,00 Canadian dollars (i.e. ~1450 US dollars or ~1285 Euros) including tax and covers transportation from Montreal to Maine and back, accommodation (based on double occupancy), field guidebook and packed lunches. If single occupancy accommodation is desired, this can be arranged at higher cost. IAVCEI membership at the time of the field trip is required. A limited amount of financial aid is available and will be granted based on need. Please submit requests for financial aid with justification and required amount to skolzenburg@xxxxxxxxx by May 31st 2019. If you have any questions regarding the trip please do not hesitate to contact me at: skolzenburg@xxxxxxxxx Please note that all participants are required to arrange their own entry documents to the USA. Failure to be admitted to the USA will result in forfeit of the fieldtrip fee. Neither the fieldtrip organisers, not the local organising committee of IUGG2019, or IUGG in general can provide assistance or be held responsible should participants fail to clear US or Canada immigration. *The belly of the beast: Exploring large magmatic systems from their roots to the surface in the intrusive complexes and volcanics of coastal Maine* This trip will introduce participants to the famed intrusive complex of Mt Desert Island, the associated bimodal volcanic succession on Cranberry Island as well as the Pleasant Bay intrusion, located in NE Maine, USA. These localities preserve evidence for a range of highly dynamic magmatic, sub-volcanic and volcanic processes. Highlights range from deep seated intramagmatic pillows and flows, diapirism, composite dikes and partial hybridization that record intimate physical, thermal and chemical interactions between mafic and felsic magmas to a remarkable and unique subvolcanic shatter zone that documents the interaction between fragmenting magma and country rock and records shallow level magma ascent during a caldera-forming eruption all the way to the surface expression, a bimodal volcanic succession, comprising rhyolitic ignimbrites, rhyolitic and basaltic lava flows and phreatic deposits. This field trip is aimed at stimulating trans-disciplinary discussion on a range of magmatic and volcanic processes. We invite participants to present their current research related to the chemical and physical development of magmatic and volcanic phenomena in informal discussion groups in the evenings. *Logistics:* This six day trip will depart from Montreal in the morning of the 18th of July and will first travel to Mt Desert Island, arriving in the afternoon on that day. We will spend two full days (19th and 20th of July) on Mt Desert Island and will focus on the Cadillac Mountain intrusion, a dissected caldera complex tilted towards the east. We will visit the eastern shatter zone documenting subvolcanic fragmentation propagating into a magma chamber during caldera collapse, as well as the western zone documenting episodic invasion of a floored silicic magma chamber by many pulses of basaltic magma. Following these days we will board a boat on the 21st of July at 9:00 am and will spend the day examining the physical volcanology of the Cranberry Island series and its implications for the relationship between the volcanic series and the Cadillac Mountain intrusive complex. The outcropping volcanic succession was rotated nearly 90Ì? from its depositional orientation, making it possible to walk from the bottom to the top of the succession in essentially 100% exposed outcrops on Great Cranberry Island. The succession includes outstanding rhyolitic ignimbrites and flow-banded rhyolites, basaltic lava flows and phreatic deposits, and an andesitic ignimbrite that preserves evidence for an origin by mechanical hybridization of rhyolitic ash and dismembered basaltic enclaves. Finally, we will spend one day (22nd of July) on the Pleasant Bay intrusion, which provides outstanding outcrops displaying the 3D architecture of liquid-liquid interactions of mafic sheets and resident silicic mush and melt, all happening at the base of a silicic magma chamber. We will return to Montreal on the evening of the 23rd of July. There will be walks up to two kilometers over moderate terrain and along the coastline. Weather conditions could range from hot to cold and rainy. Participants are required to ensure valid travel documents for entering the USA from Canada. *Trip leaders:* Stephan Kolzenburg, LMU Munich / McGill University Shane Rooyakkers, McGill University John Stix, McGill University Bob Wiebe, UC Davis Sheila Seaman, UMass Amherst ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
