Piilolinsien

Piilolinsien is a rare and enigmatic mineral discovered in the late 20th century. It is named after the Piilolin mine in Chile, where it was first found. Piilolinsien is characterized by its unique crystal structure and distinctive coloration, which ranges from deep blue to violet. The mineral is typically found in association with other copper minerals, such as malachite and azurite.

Piilolinsien is a copper sulfate hydroxide mineral with the chemical formula Cu3(OH)4(SO4). Its crystal system is monoclinic, and it often forms prismatic crystals. The mineral's hardness on the Mohs scale is approximately 3.5, making it relatively soft. Piilolinsien is soluble in water and can form efflorescent crusts in arid environments.

The discovery of piilolinsien has contributed to the understanding of mineral formation processes in copper-rich environments. Its rarity and unique properties make it a subject of interest for mineralogists and collectors alike. Despite its scientific significance, piilolinsien remains relatively unknown to the general public, adding to its allure as a rare and fascinating mineral.
