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 rocks. Straumnum's discovery has provided valuable insights into the geological processes that lead to the formation of rare earth element deposits. Its unique crystal structure and composition make it a subject of interest for both geologists and mineralogists.

Straumnum is not known to have any significant industrial applications, but its study contributes to our understanding of the Earth's crust and the processes that shape it. The mineral's rarity and aesthetic appeal make it a sought-after specimen for collectors, further highlighting its significance in the field of mineralogy.
