straumnum
Straumnum is a rare mineral discovered in 2010 by a team of geologists in the Kola Peninsula, Russia. It is named after the straum, a type of Norwegian folk art, reflecting the mineral's unique, intricate crystal structure. Straumnum is a complex oxide with the chemical formula (Y,REE)2Ti2O7, where REE stands for rare earth elements. Its crystals are typically dark brown to black and exhibit a distinctive, radiating pattern of growth, resembling the intricate designs found in straum art.
The mineral forms in high-temperature, low-pressure environments, often associated with carbonatites and other rare earth element-bearing
Straumnum is not known to have any significant industrial applications, but its study contributes to our understanding
