Marcasite specimens from the Linwood Mine (Buffalo, Scott County, Iowa, USA) are eye-catching mineral pieces prized by collectors for their metallic luster and distinctive crystal forms. Marcasite is an iron disulfide (FeS?) mineral that crystallizes in tabular, spear-like or stalactitic clusters with a bright, brassy to silvery sheen that may show slight iridescent tarnish with age. At the Linwood Mine, marcasite is often found as elongated or radiating crystal groups that display excellent surface brilliance and sculptural appeal, sometimes occurring on matrix or associated with other minerals like calcite.
