Summary of major past achievements of the project The past three years of the IGCP-628 were focused on two major efforts: (1) developing cooperation around the world in order to join efforts and thinking on the Gondwana tectonic evolution and (2) generating the new geological map of Gondwana by integration of data from all Gondwana-derived fragments. More than 250 participants are organised in thematic groups. There were thirteen meetings organised by the IGCP-628. The scientific achievements were concentrated on how to build up a paleogeological picture/map of this supercontinent. During these years the actualization and digitalization of the geological maps of all the Gondwana-derived fragments were executed. This database was built in the Gondwana Digital Center of Geoprocessing (GDCG) at the Federal University of Rio de Janeiro (UFRJ) in Brazil. Three drafts of the new Gondwana paleogeological map were published and presented to the community for evaluation. The oldest (1.1) was presented at the IGCP-628 workshop in February 2014 in Paris. In July of 2014, a more updated version (1.2) was presented during an IGCP-628 session at Gondwana 15, in Madrid (Spain). In 2015, the version 1.3 was presented and improved in a three-week IGCP-628 Gondwana Workshop, in Rio de Janeiro. The scientific community endorsed the drafts, but also made several comments and suggestions that were incorporated by the GDCG research team. It was necessary to homogenize one common legend. But the main challenge is to delineate the geological Gondwana map for the Jurassic, before the initiation of the Gondwana break up. Besides the activities developed at the Gondwana Lab, two main scientific developments are here emphasized. First is the connection with other scientific groups abroad, fundamental for the integration of the geological research of East Gondwana (Asia, Oceania and India) with the West Gondwana research through the cooperation between the geological communities of Australia-Asia with America-Africa-Europe. Many geological processes and main geological events that pre-dated Gondwana are quite similar in these continental landmasses. There is also the link with two other IGCP groups: IGCP-648 (Supercontinent Cycles and Global Geodynamics) and IGCP-592 (Continental construction in Central Asia). Second, the correlation between the geology of South America and Africa has improved with the research uniting IGCP-628 members. The main projects investigated are: “Evolution of the Gondwanides” (Sierra de La Ventana in Argentina, and Cape Fold Belt in South Africa); "Onshore-Offshore connections along the Brazilian Continental Margin"; “Tectonic evolution of the Congo Craton margin in Angola and the tectonic events in the Kaoko-Damara orogenic systems and the Ribeira-Dom Feliciano belts”; “Study of para- derived metamorphic rocks of the Neoproterozoic Madagascar belt- correlating the Brasiliano-Pan-african mobile belts”. 3. Achievements of the project this year only 3.1. General scientific achievements The main scientific achievement of the IGCP-628 this year was the publication/ presentation of the Gondwana Map draft 2.0. This version is the best update, certainly the closest version of the first edition that will be published in the end of 2017 (Annex 2). After a long effort of homogenizing the legend and proposing a best fit of the Gondwanan landmasses, the map was very well received by the geological community. The paleogeography reconstruction of this paleocontinent was possible with the use of plate tectonic interactive softwares (G-Plates and Atlas) generating a new Gondwana reconstruction for the Jurassic (ca. 183 Ma). The 2017 first edition of the map will be delivered in the end of 2017, in scale 1:5M, as a paper copy (3m versus 3m size) and also Annual IGCP report 1 Form V digital version. One of the most striking achievements of this year was the resolution approved by the CGMW, deciding to publish the 1:10M version of the IGCP-628 new Gondwana geological map. The idea is to launch this publication during the IGCP/UNESCO meetings in February 2018 in Paris. After analyzing the Gondwana map version exhibited at the 35th IGC, on scale 1:5M, CGMW group concluded that no more than one month is necessary to transform it to a less detailed version, 1:10M (Annex 3). The cooperation between South American and African scientists through field trips improved this year also. Besides the four regions that were focused in the last years: (1) Sedimentary and volcanic units from Patagonia (Devonian to Triassic) related to the tectonic evolution of the SW margin of Gondwana; (2) Metamorphic medium grade units from northeast Uruguay and south Brazil at the Dom Feliciano Neoproterozoic belt; (3) Stratigraphy of the Paleozoic-Mesozoic Parnaíba basin and its correlation with the Congo Basin; (4) Correlation between Sierra de La Ventana belt (Argentina) and Cape Fold Belt (South Africa, the Gondwanides); we started a cooperation with Angolan-Portuguese scientists in the study of the geology of SW Angola and its correlation with the SE Brazilian continent (Annex 8). Two Master dissertations and one PhD thesis related directly to the Gondwana project were finished (see item 3.6). Four new PhD thesis and four Master dissertation projects started this year related directly to IGCP-628. In 2016 we also created a new website for the IGCP-628, incorporating several sub items, such as: research themes, field trips, meetings, downloads of the Gondwana Maps, news, and Gondwana for society, among many others (Annex 10). This modern website is easily updated by the IGCP-628 secretariat. 3.2.

Educational, training or capacity building activities related to the IGCP project and IGCP project participants. During the year, the Gondwana Digital Center of Geoprocessing (GDCG) received collaborators of the IGCP-628 that conducted work-meetings with the UFRJ Laboratory GIS staff (Annex 9): Dr. Jorge Tapiaz and his co-workers from the Geological Survey of Colombia visited the Lab and gave a great input on the digitalisation process; Prof. Carlos Sommer (UFRGS – Brazil) spend one week at the Gondwana Lab discussing evolution of northern Patagonia and correlation with South Africa; Prof. Elton Dantas (UnB - Brazil) helped on the revision of the São Francisco Craton; Prof. Victor Ramos (Universidad de Buenos Aires – UBA- Argentina) stayed one week revising the Andean geological map within the Gondwana map; Prof. Gideon Rosenbaum (University of Queensland – Australia) stayed one month at the Gondwana Lab revising the eastern Australian geology and also discussing a new project on the southern Gondwana margin evolution during the Paleozoic and Mesozoic; Prof. Colin Reeves (Holland) (IGCP-628 co-leader) spend one month at the Gondwana Lab working on the reconfiguration of the Gondwana for the final map, with the research group. This year, the graduate and undergraduate students continued to be deeply involved in the IGCP-628. As pointed out in the introduction, we started to work in SW Angola as a key are of correlation between South America and Africa (Annex 8). A master student Annual IGCP report 2 Form V started a project on Madagascar geology, focused on the comparison between Pan-African and Brasiliano belts. Collaborations continued in Argentina, Uruguay and Colombia with Prof. Victor Ramos (Universidad de Buenos Aires), Prof. Renata Tommezoli (Universidad de Buenos Aires), Claudio Gaucher (Facultat de La Republica) and Jorge Bossi (Facultat de Agronomia). Also cooperation with the team from Nelson Mandela University (De Wit and Linol) generated papers on correlation between the Paleozoic basins of Gondwana and another field trip in the Cape Fold Belt, South Africa. A paper on the comparison between this belt and the correlate South American Sierra de La Ventana system is being written. 3.4.
