Located at the equator, in the alignment known as the \u201cCameroon Volcanic Line\u201d, this archipelago represents a privileged area for the comparative study between oceanic and continental alkaline volcanism, and therefore between the subcontinental and suboceanic mantle. Ten geosites of S\u00e3o Tom\u00e9 island were selected, described and evaluated on the basis of their geoheritage value and using a qualitative system of classification, which integrates both the meaning attributed to the objects by scientific communities and the public understanding of such meanings related to its social use. The selected geosites display different heritage values (documental, scenic, symbolic, iconographic and indicial) potentially usable for different purposes, namely scientific and educational, but mostly tourism. Geotourism can play a key role in the promotion of sustainable development in the Democratic Republic of S\u00e3o Tom\u00e9 and Pr\u00edncipe, and the geosites here described are likely to ground a geo-itinerary on this \u201cpearl\u201d of the Cameron Line.     <\/jats:p>","DOI":"10.3390\/su7010648","type":"journal-article","created":{"date-parts":[[2015,1,7]],"date-time":"2015-01-07T12:35:46Z","timestamp":1420634146000},"page":"648-667","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Geoheritage at the Equator: Selected Geosites of S\u00e3o Tom\u00e9 Island (Cameron Line, Central Africa)"],"prefix":"10.3390","volume":"7","author":[{"given":"Maria","family":"Henriques","sequence":"first","affiliation":[{"name":"Department of Earth Sciences and Geosciences Centre, Faculty of Sciences and Technology, University of Coimbra (Polo II), Rua S\u00edlvio Lima, 3030-790 Coimbra, Portugal"}]},{"given":"Keynesm\u00e9nio","family":"Neto","sequence":"additional","affiliation":[{"name":"Instituto Superior de Educa\u00e7\u00e3o e Comunica\u00e7\u00e3o, University of S\u00e3o Tom\u00e9 e Pr\u00edncipe and Geosciences Centre, Faculty of Sciences and Technology, University of Coimbra, Rua Padre Martinho Pinto da Rocha, No. 939, Caixa Postal No. 300, S\u00e3o Tom\u00e9 e Pr\u00edncipe, 3030-790 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2015,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1016\/0012-821X(85)90114-1","article-title":"The Cameroon Line, West Africa and its bearing on the origin of oceanic and continental alkali basalt","volume":"72","author":"Fitton","year":"1985","journal-title":"Earth Planet.
