Scientists submit their candidate Revealed to Be New Mineral material to a battery of tests and build a case for its novelty. To do so for merelaniite, Jaszczak sought help from scientists all over the world to determine the mineral’s crystal structure and properties such as density, opacity, and reflectiveness, among others. The CNMNC receives about 120 new mineral proposals each year, of which it approves about 100, said Peter Burns, IMA president and an environmental chemist at the University of Notre Dame in Notre Dame, Ind. Currently, IMA lists 5179 unique minerals, but only a few boast a curved structure like merelaniite’s, said Burns, including one called cylindrite. As they investigated the new material, Jaszczak and his colleagues learned that its oddly curving shape resulted from a pattern of alternating layers: one of mostly molybdenum disulfide, then two layers of predominantly lead sulfide, then molybdenum disulfide again, and so on. A mismatch of bonding lengths between atoms across layers causes the curvature as atoms try to match up, warp- ing the mineral structure, Jaszczak said. After 4 years of testing and several months waiting for the CNMNC to deliberate, Jasz- czak’s team heard the news: Merelaniite was John Jaszczak approved. The new mineral merelaniite, which to the naked eye looks like incredibly fine hairs. This particular sample stretches “I really wish that I had been given the less than 2 millimeters tall. A chance discovery by a junior mineral enthusiast led to a new entry in the International opportunity to get in on the research,” said Mineralogical Association’s list of minerals. now 18- year- old Jessica Simonoff, because she was studying the original sample of tanzanite on which the merelaniite was first spotted, oftware engineer Bob Simonoff didn’t own lab at Michigan Technological University albeit for different purposes. These days, she’s realize that he was looking
