Summary
| Description |
English: This massive sulfide rock from Pennsylvania's Gap Nickel Mine consists of three types of fool's gold:
1) Pyrrhotite (Fe1-xS, imperfect iron monosulfide) - pyrrhotite is magnetic and has a metallic-lustered, light brownish appearance 2) Pentlandite ((Fe,Ni)9S8, iron nickel sulfide) - a type of fool's gold that has nickel 3) Chalcopyrite (CuFeS2, copper iron sulfide) - a type of fool's gold that has copper, with a bright golden brassy appearance. This deposit was discovered in the early 1700s and sporadically mined for copper to the early 1800s. In the latter 1800s, it was mined for copper and nickel. The principal nickel-bearing ore minerals are pentlandite and millerite (NiS, nickel sulfide). Nickel also occurs as an impurity in pyrrhotite at this site. The dark reddish-brown and yellowish-brown in the sample are iron oxides - hematite and limonite. Locality: Gap Nickel Mine, southeast of the town of Lancaster, southeastern Lancaster County, Pennsylvania, USA (39° 57' 31.22" North latitude, 76° 04' 59.58" West longitude) Locality info. at: www.mindat.org/loc-4085.html |
