kinloppuliite

Kinloppuliite is a fictional mineral used in mineralogy education and in illustrative discussions of phosphate minerals. It is described as a potassium-indium phosphate and is not a recognized mineral species in formal catalogs. The hypothetical composition is described as containing potassium (K), indium (In), and phosphate (PO4) groups, with possible minor substitutions by aluminum (Al) and iron (Fe). It is commonly attributed to a monoclinic crystal system, with a prismatic habit in well-formed crystals; color range pale yellow to pale green; luster vitreous; transparency from transparent to translucent; and a hardness around 4 to 5 on the Mohs scale. Cleavage is typically imperfect, and fracture is conchoidal to uneven.

Occurrence and associations: In fictional accounts, kinloppuliite is said to originate in oxidized zones of granitic pegmatites, with a pretend type locality. It is described as rare and typically found in association with other phosphate minerals such as apatite and xenotime. No verified natural specimens are publicly documented in major mineral databases.

Discovery and naming: The name is constructed from a fictitious locality used in teaching examples; it does not reflect a confirmed discovery.
