Trinitite (AKA atomsite or Alamogordo glass), is the glassy residue left on the desert floor after the Trinity nuclear bomb test on 7/16/45 near Alamogordo, NM. It's primarily composed of arkosic sand composed of quartz grains and feldspar (both microcline and smaller amount of plagioclase with small amount of calcite, hornblende and augite in a matrix of sandy clay) that was melted by the atomic blast. It is usually a light green, although color can vary. It is mildly radioactive.
