8th International Symposium on
Andean Geodynamics (ISAG)

You can download the up-to-date programme here.

 

The +6000 km-long Andean Cordillera represents a unique natural laboratory for studying the geological and geodynamical process associated with the construction and development of a continental mountain range. A decade after the last ISAG in Nice, we have decided to revive this unique symposium on Andean geology and geodynamics but also its related economical and social issues. Because these topics are of major importance for Andean countries, the 8th International Symposium on Andean Geodynamics (ISAG) will be held in Quito, Ecuador on September 24-26th, 2019.

The next ISAG is being organized by the Instituto Geofísico, Escuela Politécnica Nacional (IG-EPN) of Quito (Ecuador) and the French Institut de Recherche pour le Développement (IRD), and will be held on the Hotel Mercure Alameda Quito, the official hotel for the ISAG.

We expect that ~250 earth scientists will attend the conference. Given the number of submitted abstracts and the current level of registrations, we are confident that this symposium will be an exciting forum for scientific exchange between Earth scientists from South America, Europe, and North America.

 

Conference languages
For both, oral and poster sessions, the preferred language is English, although Spanish or French are also accepted. However, there will be no facilities for simultaneous translation.

 

Registration

Tectonic deformations, and in particular vertical movements, recorded by the coastal domain above the Ecuadorian subduction zone reflect a complex geological history. These vertical movements can be quantified at different time scales, at the short-term from the scale of the seismic cycle to many cumulated cycles (100 ka) to the long-term (Ma) by combining tectonic markers. In this fieldtrip, we propose to explore vertical movements through morpho-tectonic markers of coastal uplift (uplifted marine terraces) and sedimentary and stratigraphic markers of formation of the Coastal Cordillera (evolution of forearc basins). This fieldtrip will focus on Manta Peninsula and La Plata Island. The observed markers will be placed in their seismic, tectonic and geological context.

Please note that this fieldtrip will be done in spanish.

Cotopaxi volcano is one of the most active and iconic stratovolcanoes of the Ecuadorian Andes. Its history covers more than 0.5 Ma and includes the rhyolitic explosive deposits of its Pleistocene volcanic history, including the (~200 ka, 100 km3 ) Chalupas ignimbrite. During this fieldtrip, we will also observe the eruptive products of the last 7000 ka, that includes rhyolitic tephra fallout and pyroclastic flow deposits, debris avalanche and lahar deposits, and the historical scoria flows and debris flows deposits.

The Chingual-Cosanga-Pallatanga-Puna fault system is a major tectonic feature of the northern Andes, which accommodates the relative displacement (8 mm/a) between the North Andean Sliver and the South America Plate (Alvarado et al., 2016). The fault system imprints are strikingly similar to those of other major continental fault zones in the world. It includes a series of parallel or branching active fault strands, which historical activity is suggested by major and damaging earthquakes since at least the 17th century (Yepes et al., 2016).

During this 4-days field trip, we plan to present, among other short stops, the most prominent geomorphological and geological evidences of fault activity along this system, including surface ruptures associated with moderate and large magnitude earthquakes. We will have a look at Quito fault zone (Alvarado et al., 2014), then drive to the south in order to get an overview of recently studied active faults. We will have a look at the Pallatanga fault in Rumipamba where the first trenches in Ecuador were performed to find back the source of 1797 M7.5+ Riobamba earthquake (Baize et al; 2015) and drive uphill to the Pisayambo Laguna area where a M5 earthquake ruptured the fault system up to the surface (Champenois et al., 2017). We will also make a detour to the Igualata volcano summit (4500m) to observe a surface rupture, which is probably associated with the major Riobamba earthquake (Baize et al., in prep).

The Eastern Cordillera of Ecuador is an Andean trending magmatic and metamorphic belt that exposes rocks spanning from the Palaeozoic basement to the modern active arc, and records the early disassembly of Pangaea in the Triassic, subsequent prolonged Jurassic - Early Cretaceous active margin magmatism during hyper-extension, and the collision and accretion of the Caribbean Large Igneous Province in the late Cretaceous. The field trip plans to make the following stops: (1) Ammonite bearing quartzites and slates of the Chaucha Block, which is considered to be para-autochthonous continental crust that rifted from South America during Early Cretaceous hyper-extension (stop close to the town of Alausi); (2) The Peltetec sequence, which is a tectonic melange that hosts ultra-mafic and mafic lithologies, which range in age from Neoproterozoic to Early Cretaceous, and is considered to have formed during the closure of an Early Cretaceous basin that was floored by a transitional mafic crust; (3) Tungurahua Volcano, which is part of the modern arc and has been continually erupting since 1999 until the mid-2016; (4) A west-to-east traverse across the Cordillera, where we will cross Triassic anatectites that formed during a rift-to-drift transition, and Jurassic-Early Cretaceous arc rocks that formed in a prevailing extensional setting.

The southern sector of Ecuador (between 2°S and 6°S) has been characterized by intense magmatic activity in the period comprised between Oligocene and Miocene (Hungerbuhler et al. 2002). The volcanic sequence in the Pucará-Santa Isabel sector is composed by the Saraguro Fm. (26-21 Ma) followed by the St. Isabel Fm. (18 – 7.6 Ma) and closed by the Tarqui Fm. (6.3 Ma). These volcanic formations, made principally of welded ignimbrites, show large lithofacies variability (boulder size to lapilli size lithics, crystal rich to fiamme-rich ignimbrites) that reflects different PDC run-out and principally different sources. Stratigraphic and geomorphologic constraints allow to locate calderas structures (mean diameter 13 x 7-km) related with the Jubones and Santa Isabel ignimbritic eruptions.

The cretaceous Alamor-Lancones basin is located into the Huacabamba deflection, a geographic region which represents the transition between Central to Northern Andes, where the Cordillera change from NW to NE trend. The basin is limited by Triassic metamorphic blocks, the Amotape-Tahuin to the northwest and the Loja Terrane to the Southeast.

The Alamor-Lancones basin can be divided into a northwestern quartz-rich domain and a southeastern volcaniclastic domain (Jaillard et al, 1999). The earliest volcanism accompanying rifting is dominated by basaltic pillow lavas and breccias with related VMS deposits formed between 104 to 100 Ma. A second phase of felsic-rich volcanism with ages of 99 to 91 Ma intercalated and overlain by siliciclastic and carbonate sedimentary sequences in northwestern section of the basin (Winter, 2008), at this time the Bramaderos porphyry was deposited (Schutte, 2010) and possible related epithermal vein systems at its borders.

The aim of the field trip is go through the basin from the northwest area in the contact between metamorphic rocks and overlain sedimentary western domain toward the southeastern domain where dominated volcanism with porphyry and epithermal deposits are present on the upper sequences and ending in the lower basaltic sequences.

Different groups working in Ecuador proposed several pre-symposium fieldtrips. The logistics of these fieldtrips is being assured by our local logistics team following the requests from each field-trip leader. We should stress that the scientific part of these fieldtrips is also under the responsibility of the fieldtrip leaders.

The cost of each field trip includes bus and/or air transport, lodging in double occupancy rooms, breakfast, box-lunch, and field guides. These prices do not include dinners. All taxes are included. Given that there are logistic limitations, the number of participants will be restricted.

Field trips will start from the official Hotel Mercure. Please be ready to go 20 minutes before departure time.

Note: Participants are advised that we will be at high elevations, up to 4500 m above sea level (asl). Please be sure that your health is compatible with being at these altitudes. Above 3000 m asl, temperatures will generally be between 5 – 20°C; driving rain and strong winds are possible. Sunscreen, hats, and adequate clothing are necessities. Water and lunch will be provided in the field. The organizing committee will not be responsible for any accidents that might occur during the trip. Participants are recommended to have their own health and travel insurance.
