5th International Maar Conference (5IMC)
************************************************************************************************
Dear colleague,
Please find information below about the upcoming 5th International Maar Conference (5IMC): a multidisciplinary congress on maars, crater-lakes, and monogenetic volcanism, which will be held in Querétaro, México, on 17-22 November, 2014. We hope you will consider presenting the results of your research in the 5IMC.
Best regards,
Gerardo Carrasco and Jorge Aranda
Co-chairs of the 5IMC

Scope
Mexico’s geodiversity makes it a unique natural laboratory where volcanism of different ages and styles is widely exposed along the country. In addition to the large stratovolcanoes that characterize the landscape of the central part of Mexico, large monogenetic volcanic fields, mainly formed by clusters of scoria cones, maars, lava domes, and extensive lava fields are common in the Trans Mexican Volcanic Belt (TMVB), an active subduction-related arc. TMVB monogenetic fields are dominated by basaltic andesites, but some, such as the Serdán Oriental and Valle de Santiago fields, display a broad spectrum in lava compositions from mafic alkalic to rhyolitic. The most famous example of a monogenetic eruption in Mexico is that of the Paricutin volcano, which erupted from 1943 to 1952, forming part of perhaps the largest dominantly monogenetic field worldwide, the Michoacán-Guanajuato volcanic field.
North of the TMVB, mantle and lower crustal xenolith-bearing mafic alkalic rocks are associated with scattered maar- and scoria cone-forming vents within a broad region that is considered the southern extension of the Basin and Range Province.
Following the trend established in the previous meeting in New Zealand, the 5th International Maar Conference will focus on both maars and other types of monogenetic volcanoes. We have proposed sessions related to the architecture and evolution of these types of volcanoes, as well as in environmental studies, crater lakes, structural and tectonic settings, hazards, economic and cultural aspects, analog experiments and modeling.
Several field trips will be scheduled during this meeting, which will allow the participants to explore a diversity of volcanic landforms but with a focus on maars. All trips will visit sites that have particular features controlling the formation of maars, allowing discussion on topics including, but not limited to, fractured vs. granular aquifer conditions, migration of locus of explosions, magma composition, dry-to-wet and wet-to-dry evolutionary trends, structural setting, role of eruption rate. Examples of well-documented maars and other monogenetic volcanoes will be explored in detail due to the well-preserved exposures in the selected sites.

Location and Access
Querétaro is conveniently located in the geographic center of México. It is only 210 km north of Mexico City and it is the first stop for many travelers on the country’s circuit of colonial-era cities.
How to get Queretaro:
By plane- Querétaro International Airport (AIQ) is 34 km east of Querétaro city, offering convenient international connections to Houston & Dallas, Texas (USA)
By bus- Regular bus service connections are scheduled hourly between terminals 1 and 2 of Mexico City’s International Airport and Querétaro bus terminal, with the trip taking about three hours.
By car- Driving from Mexico City takes about 2.5 hours by federal Highway 57.
Information about Querétaro
Queretaro is a modern industrial city built around a beautiful colonial center. It is one of the safest and cleanest cities of the country, with a wide range of tourist attractions including historic haciendas converted into luxurious hotels. The city was the third most important city during Mexico’s colonial era, when Spain governed the land. Today it is a favorite spot for rest and relaxation. The colonial city of San Miguel de Allende, the magnificent Peña de Bernal (claimed to be one of the largest worldwide monoliths), Tequisquiapan hot springs and the Ezequiel Montes vineyards are within 45 minutes drive from Querétaro. Some of these localities are considered “Magic Villages”, towns that have been selected by Mexico's Ministry of Tourism as localities that “hold a very special cultural, historical or social importance” within the country (http://www.explorandomexico.com/about-mexico/4/217/)
Querétaro's historic downtown was declared a World Heritage Site by the United Nations Educational, Scientific and Cultural Organization (UNESCO) for its rich history and unmatchable collection of baroque-style mansions, houses and churches. Mexico’s independence from Spain began right in the heart of Querétaro's downtown, where conspirators held clandestine meetings to plan their rebellion.
