Szenicsite is a copper hydroxy molybdate mineral, named after husband and wife Terry and Marissa Szenics, American mineral collectors who found the first specimens. When it was first discovered in Atacama, Chile, it was thought to be lindgrenite. The occurrence appeared in an isolated area, which was about one cubic meter in size. The mineral occurred in cavities of copper bearing powellite and matrix rich molybdenite. These cavities were filled with a material resembling clay. Outside of the zone the szenicsite crystals grew, copper levels seemed to decrease, and the mineralization changed to

Brianyoungite is a secondary zinc carbonate mineral. The Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA) classifies it as a carbonate with the formula , but sulfate groups SO4 also occupy the carbonate CO3 positions, in the ratio of about one sulfate to three carbonates, so other sources give the formula as , and Gaines et al. classify the mineral as a compound carbonate. It is similar in appearance to hydrozincite, another zinc carbonate. It was discovered in 1991 and designated IMA1991-053. In 1993 it was named "briany

Malhmoodite is a phosphate mineral first discovered at a mine called Union Carbide in Wilson Springs, Arkansas, United States. This mine is 10 km west of Magnet Cove, an alkaline igneous complex, and Union Carbide is in a contact region of alkalic igneous rocks and surrounding sedimentary rocks. The mineral has been approved by the Commission on New Minerals and Mineral Names, IMA, to be named for the late Bertha K. Malhmood, the Administrative Assistant of the Branch of Analytical Laboratories, U.S. Geological Survey.

Fangite is a sulfosalt first discovered in the Mercur gold deposit located in Tooele County Utah. The specimen was found in a boulder in the southern Oquirrh Mountains. The only available specimens of fangite are located in the National Museum of Natural History, Smithsonian Institution. The International Mineralogical Association Commission approved the name Fangite after Dr. Jen-Ho Fang, a crystal chemist affiliated with the University of Alabama, in honor of his significant contributions to crystallography, crystal chemistry, and geostatistics.
