Platinum (original) (raw)

Colour:

Steel grey to dark grey

Name:

From Spanish "platina", diminutive of "plata", silver. The new metal found in large placer deposits during the sixteenth-century Spanish conquest of South America was called "platina del Pinto" after the Rio Pinto, Colombia.

Palladium-Platinum Series.

Note that true native platinum in the mineralogical species sense is a rather rare mineral, and most of the specimens so labelled are in fact isoferroplatinum or intimate mixtures of isoferroplatinum and tetraferroplatinum.

This map shows a selection of localities that have latitude and longitude coordinates recorded. Click on the symbol to view information about a locality. The symbol next to localities in the list can be used to jump to that position on the map.

- This locality has map coordinates listed. - This locality has estimated coordinates. ⓘ - Click for references and further information on this occurrence. ? - Indicates mineral may be doubtful at this locality. - Good crystals or important locality for species. - World class for species or very significant. (TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality. Faded * - Never found at this locality but inferred to have existed at some point in the past (e.g. from pseudomorphs).

All localities listed without proper references should be considered as questionable.
