Named for the Gal-Khaya arsenic-mercury-tin deposit in the eastern-Siberian region of Russia where the mineral’s type locality is located. Galkhaite is a rare mineral that is additionally found in the United States, Canada, and newer localities in Iran, Italy, and Kyrgyzstan. Galkhaite occurs in hydrothermal mercury-gold deposits.

Named for the Greek word ganoma, meaning a “tinker” or “glaze,” in reference to the minerals lustrous, glazed appearance. Occurs in Sweden, the United States, and China only. Found in skarn assemblages at the locality in Jakobsberg, Sweden and in manganese ores at Franklin in New Jersey, USA. Associated minerals include tephroite, lead, jacobsite, calcite, phlogopite, macedonite, clinohedrite, willemite, andradite, and franklinite.

Named for Blair J. Gartrell, an Australian mineral collector who discovered the mineral. It is a rare mineral that occurs in oxidized and mineralized shear zones that cut greywacke and shale at one of its Australian localities at the Anticline prospect, and on fine grained quartz-spessartine rocks at another Australian locality at Broken Hill. Other localities for Gartrellite include in Germany, Namibia, the United States, and a few others.

Named for Dr. Bryan Michael Kenneth Cummings Gatehouse who was a crystal chemist at Monash University in Melbourne, Australia. Gatehouseite is a rare mineral which has its type and only locality at the Iron Monarch open cut in South Australia. There, it occurs “as a secondary mineral in cavities in a sedimentary Fe-Mn deposit, probably formed by reaction of phosphate-rich fluids with hausmannite at low temperature.
