The archaeological settlement site of Playa Grande on the northern coast of the Dominican Republic is particularly significant because it yielded evidence of on-site axe manufacture, and lies only 20\u201330 km NE of a recently discovered potential source area of serpentinite m\u00e9langes in the nearby R\u00edo San Juan Complex (RSJC). A suite of nine artefacts was chosen from a collection of over 100 excavated woodworking tools rich in jadeite, as well as two blueschist artefacts. Permission to perform destructive analysis allowed data on petrography, mineral chemistry and bulk-rock chemistry to be obtained. Seven of the nine artefacts are jadeitite<jats:italic>sensu stricto<\/jats:italic>(&gt;90 vol% jadeite), which are identical to material known from the RSJC. Two artefacts are jadeite\u2013lawsonite rocks. These and the two blueschists show only minor differences from corresponding rocks of the RSJC source. With this direct linking of source and site material, it is now possible to better define source discriminators for the Caribbean and to assess sampling bias.<\/jats:p>","DOI":"10.1144\/sp474.3","type":"journal-article","created":{"date-parts":[[2018,3,13]],"date-time":"2018-03-13T00:10:34Z","timestamp":1520899834000},"page":"231-253","update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Petrography, mineralogy and geochemistry of jadeite-rich artefacts from the Playa Grande excavation site, northern Hispaniola: evaluation of local provenance from the R\u00edo San Juan Complex"],"prefix":"10.1144","volume":"474","author":[{"given":"Hans-Peter","family":"Schertl","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Geologie, Mineralogie und Geophysik, Ruhr-Universit\u00e4t Bochum, 44780 Bochum, Germany"},{"name":"College of Earth Science and Engineering, Shandong University of Science and Technology, Qingdao, Shandong 266590, China"}]},{"given":"Walter V.","family":"Maresch","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Geologie, Mineralogie und Geophysik, Ruhr-Universit\u00e4t Bochum, 44780 Bochum, Germany"}]},{"given":"Sebastiaan","family":"Knippenberg","sequence":"additional","affiliation":[{"name":"Faculteit Archeologie, Caribbean and Amazonia, Reuvensplaats 3\u20134, 2311 BE Leiden, The Netherlands"}]},{"given":"Andreas","family":"Hertwig","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Geologie, Mineralogie und Geophysik, Ruhr-Universit\u00e4t Bochum, 44780 Bochum, Germany"},{"name":"Present address: Department of Geoscience, University of Wisconsin-Madison, 1215 W Dayton Street, Madison, WI 53706, USA"}]},{"given":"Adolfo","family":"L\u00f3pez Belando","sequence":"additional","affiliation":[{"name":"Calle Fantino Falco No. 47, Edificio Naco 2000, Suite 804, Santo Domingo, Dominican Republic"}]},{"given":"Reniel","family":"Rodr\u00edguez Ramos","sequence":"additional","affiliation":[{"name":"Universidad de Puerto Rico, Recinto de Utuado, Utuado, Puerto Rico"}]},{"given":"Laura","family":"Speich","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Geologie, Mineralogie und Geophysik, Ruhr-Universit\u00e4t Bochum, 44780 Bochum, Germany"},{"name":"Present address: School of Earth Sciences, University of Bristol, Queen's Road, Bristol BS8 1RJ, UK"}]},{"given":"Corinne L.","family":"Hofman","sequence":"additional","affiliation":[{"name":"Faculteit Archeologie, Caribbean and Amazonia, Reuvensplaats 3\u20134, 2311 BE Leiden, The Netherlands"}]}],"member":"1881","published-online":{"date-parts":[[2018,3,12]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.earscirev.2014.08.007"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-444-42148-7.50008-3"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ea.16.050188.001221"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1127\/0935-1221\/2012\/0024-2171"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.1127\/0935-1221\/2011\/0023-2164"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1130\/SPE262-p77"},{"key":"e_1_3_3_9_1","volume-title":"Mapa Geol\u00f3gico de la Rep\u00fablica Dominica: Hojas de R\u00edo San Juan, Guayabito, Salcedo, Gaspar Hern\u00e1ndez, Pimentel, Cabrera y Villa Riva [Geological Map of the Dominican Republic: Sheets R\u00edo San Juan, Guayabito, Salcedo, Gaspar Hern\u00e1ndez, Pimentel, Cabrera and Villa Riva]","author":"Escuder-Viruete J.","year":"2010","unstructured":"Escuder-VirueteJ. 2010.
