The purpose of the proposed IGCP project is to bring together researchers working on both sides of the northern Atlantic Ocean, to discuss connections among northwest Africa, eastern North America and Iberia during the Paleozoic. The project is primarily focused on the crustal fragments of Northwest African origin that are now located in eastern North America and Iberia, but also on fragments and traces of the microcontinent Avalonia that may exist in all three continents. Microcontinents Cadomia (in Iberia) and Meguma (in eastern North America) have been interpreted as having a (partial) NW African origin. Avalonia has Amazonian or West African, or perhaps Baltic, origin. Fragments of it now occupy large parts of eastern North America and Europe (including Iberia), and likely NW Africa (northern Morocco). Rock types, structures and natural resources may be correlated between northwest Africa, eastern North America and Iberia, and their origins will be much better understood if/when scientists who do research in these three areas would work together.

The purpose of our three field meetings is to bring together scientists who work in northwest Africa, eastern North America and Iberia, and compare and contrast all of the above among the three areas. It is our goal to have three field-based meetings during the duration of the project, one in each of the three areas, to initiate and foster collaboration between these scientists, and to provide a venue to learn about each other’s research.

Project Fieldtrips: 

2021 (Morocco) – Postponed to 2024 due to COVID.

 The first fieldtrip was planned to be in Morocco to cover parts of the Anti-Atlas and Western Meseta domains, focusing on general geology, rock types and Variscan deformation. It will now likely be the final field trip of the project. The field trip will be five days and include talks and discussions in the early evenings. This fieldtrip will be co-organized with local mining groups and the Geological Survey of Morocco. It will include a celebratory closure of the project.

Preliminary dates: 22-27 May 2024.


2022 (Canada and USA)

The first fieldtrip will be a five day-transect through Nova Scotia, Canada, from the Meguma terrane through Avalonia (northern mainland Nova Scotia and southeastern Cape Breton Island) to Ganderia (central Cape Breton Island). Evening sessions will include discussions and virtual field trips to southeastern New England, USA (Avalonia and/or NW African fragment), with visits to other Appalachian terranes along the way. The field trip will be May 19-23, 2022, and will be proceeded by an IGCP683 symposium at the GAC-MAC-IAH-CSPG meeting in Halifax, May 15-18.

Dates: 19-23 May 2022.


2023 (Portugal and Spain)

The second field trip will be held in Spain and Portugal, starting in the north of the Central Iberia Zone, going through the Ossa-Morena Zone and ending in the South Portuguese Zone. This will be 5 days of field trip preceded by 2 days of workshop in Granada in 2023.

Preliminary dates are Spring 2023.
