Goldmanite (original) (raw)
Colour:
Green, brownish-green
Specific Gravity:
3.74 - 3.77
Name:
Named in 1964 by Robert H. Moench and Robert Meyrowitz in honor of Marcus Isaac Goldman (11 January 1881, New York, New York, USA - 2 October 1965, Washington D.C., USA), sedimentary petrologist with the United States Geological Survey. He, along with A. C. Spencer, studied the Entrada Sandstone, the host rock at the type locality.

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
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.
