Four alteration minerals: alunite, kaolinite, muscovite and montmorillonite were detected by subpixel unmixing analysis of the ASTER reflectance data. This study compared different methods for extracting mineralogic information from ASTER data, compared the remotely derived maps to the mapped field geology, and used the ASTER data to map minerals and lithologies related to gold exploration.

GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S. JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu tions with silver, copper, nickel, palladium, and
Gold is malleable enough for just 1 gram to be hammered into a sheet 1 square meter in size. It can also be made so thin that it appears transparent. Due to a similar appearance to gold, the mineral pyrite has the nickname fool's gold.
Minerals are materials that meet five requirements. They are: 1) naturally occurring, 2) inorganic, 3) solids, 4) with a definite chemical composition, and, 5) an ordered internal structure.

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear goldlike, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden
When gold predominates (Au,Ag) the mineral species is called gold (native gold) and when silver predominates (Ag,Au) it is termed silver (native silver). The variety electrum is usef for compositions between about 2080% gold or 2080% silver atoms. Highly pure gold is rarely found, it almost always contains some silver.
