Kaatialaite

Named after the type locality in the Kaatiala pegmatite in Finland. Kaatialaite is a rare mineral that occurs in granite pegmatites and in oxidized silver-arsenic veins in gabbro. Additional localities include in Germany, the Czech Republic, and the United States. Associated minerals include arsenolite, lollingite, calcite, and gypsum. The water content of the mineral is variable depending on relative humidity. It will also become cloudy upon exposure to light.

Kaersutite

The type locality at Qaersut, which was formerly called Kaersut, in Greenland, is the namesake for this mineral. It occurs “as phenocrysts in alkalic volcanic rocks, in gabbroic and peridotitic nodules in alkalic basalts, in syenites, monzonites, carbonatite tuffs, and alkalic gabbros.” Localites include in Greenland, Italy, the Czech Republic, the United States, Canada, Japan, and New Zealand among other localities.

Kainosite-(Y)

Named after the Greek word kainos, meaning “unusual,” in reference to its rarity and exotic composition. Kainosite can be found in pegmatite and granite vugs. Localities for Kainosite can be found in Norway, Sweden, Switzerland, Austria, Italy, Russia, the United States, and Canada. Assocaited minerals include chamosite, pyrite, quartz, calcite, sphalerite, fluorite, uraninite, zircon, molybdenite, diopside, magnetite, clinochlore, and apatite.

Kambaldaite

Named for Kambalda in Western Australia, where Kambaldaite has its type locality. Kambaldaite is a rare secondary mineral that can be found in goethite residues that was formed by the oxidation of violarite-pyrite with associated carbonates and saline groundwater. Localities for Kambaldaite can be found in, additionally, Austria, and Brazil.

Kamotoite-(Y)

Named after the town of Kamoto, and the Kamoto mine in the Democratic Republic of the Congo where the mineral gets its type locality. Kamotoite is a rare mineral that forms in oxidized uranium-bearing copper-cobalt deposits. It can be found in additional localities in Switzerland, Norway, Germany, the Czech Republic, and Canada. Kamotoite is radioactive.
