IGCP 648 2019 Field Symposium

22 June – 6 July, 2019 | Madagascar

Madagascar has been the scene of much discussion and new research over the last two decades by a wide group of international authors. It is a spectacular country in terms of hospitable people, amazing scenery, flora and fauna and incredible geology. Come and discuss, teach and learn with us in Madagascar for the IGCP 648 meeting in 2019.


Scientific Program

The symposium will  include ten days of field trip followed by two days of conference. The provisional program is:

Jun. 22, 2019 (Saturday), Arrival at Antananarivo.

Jun. 23, 2019 (Sunday) – Jul. 2, 2019 (Tuesday), Pre-conference field trip.

Jul. 3, 2019 (Wednesday), Networking and poster session.

Jul. 4, 2019 (Thursday) – Jul. 5, 2019 (Friday), Conference in Ifaty.

Jul. 6, 2019 (Saturday), Bus back to Antananarivo.


Field Trip

The field trip will follow a transect from east to south west across the island, from the Antongil Domain through the Antananarivo Domain and the Itremo Domain. We will see the stranded Dharwar craton remnant in the east, pass through the controversial Betsimisaraka suture and see highly deformed charnockites, graphitic paragneisses and orthogneisses along a transect from Brickaville (on the east coast) through the Andasibe National Park rich in Indri lemurs, to the capital Antananarivo. There we’ll examine outcrops of the Neoarchaean Betsiboka Suite and the Palaeoproterozoic (or is it Tonian!) Ambatolampy Group of the Antananarivo Block. We will see the low-grade contact of the Itremo Domain over the Betsileo Shear Zone that has been interpreted as a major extensional detachment and see excellent examples of the Tonian continental arc (or are they a LIP?) of the Itsindro-Imeroma Suite. We will see the famous stratoid granites of the Ambalavao Suite and high grade cordierite gneisses at Ihosy before passing into the sapphire-bearing Karoo rocks and end in the beautiful beach resort of Ifaty.

Following the conference in Ifaty, participants will be transported back to the capital by bus.
