“…The source of this material, on the other hand, is unknown. The well-known sources of turquoise are located far in the American Cordillera, both in North and South America (Queffelec, 2021), while a source is mentioned in coastal Brazil (Costa et al, 2004), and a single source is known so far in the Caribbean, in the US Virgin Islands (Alminas et al, 1994;Tucker et al, 1985). The application of non-destructive isotopic analysis of copper, as proposed by Hull et al (2008), and of lead, as measured destructively by Thibodeau et al (2012), is not straightforward to implement without risk for the analyzed artifacts and with good reproducibility.…”

“…En revanche, la source de ce matériau est inconnue. Les sources bien connues de turquoise se trouvent à grande distance dans la Cordillère des Amériques, à la fois en Amérique du Nord et du Sud (Queffelec, 2021), tandis qu'une source est mentionnée sur la côte brésilienne (Costa et al, 2004), et qu'une seule source minime et peu étudiée est connue jusqu'à présent dans les Caraïbes, dans les îles Vierges américaines (Alminas et al, 1994;Tucker et al, 1985).…”

“…Even though the geology of St. Thomas and St. John has been investigated (Cleve, 1882; Donnelly, 1959; Earle, 1924; and Meyerhoff, 1926), there is still controversy as to the origin and age of the islands. Mineralogy of the islands include feldspars, quartz, calcite, magnetite, and zircon (Tucker et al, 1984). The landforms are well‐defined, with many alluvial‐colluvial fans forming at the base of the mountains.…”
