Gobbinsite

Named for the type locality at Hills Port in Gobbins on Island Magee in Northern Ireland. Gobbinsite is a rare mineral that occurs as a secondary mineral in basalts, and in cavities in sodalite syenite. Localities for Gobbinsite include, additionally, in Canada, as well as newer localities in the United States, Russia, New Zealand, Japan, and Hungary.

Godovikovite

Named after Aleksander Aleksandrovich Godovikov, former Russian mineralogist and Director of the Fersman Mineralogical Museum in Moscow, Russia. Localities for Godovikovite include in Russia, and Tajikistan, as well as a few others. It occurs “as reaction crusts around outlets releasing sulfuric acid from burning coal heaps,” and is associated with anhydrous calcium and magnesium sulfates. Godovikovite is soluble in water.

Goethite

Named to honor German poet, dramatist, and philosopher, Johann Wolfgang von Goethe. Goethite is a common mineral that forms as a product of the weathering of iron-bearing minerals oxygen-rich environments and is a component of iron ore, and it is a precipitate in hydrothermal, marine, and bog environments in reduced iron waters.  Good crystals come from localities in Germany, the Czech Republic, England, France, and the United States.

Gold

Named from antiquity as the Old English word for the metal, and possibly related to the Sanskrit wok jval. The chemical symbol, Au, comes from the Latin word for gold, aurum. Gold is a common and widespread mineral in small amounts in rocks of many kinds as well as in sea water. It is found in epithermal veins, pegmatites, contact metamorphosed deposits, and in placers. Localities for fine specimens include in Russia, Romania, Australia, New Guinea, South Africa, Canada, the United States including famously here in the Black Hills of South Dakota at the Homestake mine, Venezuela, and Brazil. Hundreds of other minor localities.
