large group of linarite crystals growing in "limonite" cavity.
Linarite : PbCu(SO4)(OH)2
Linarite occurs as monoclinic prismatic to tabular crystals and irregular masses. It is easily confused with azurite, but does not react with dilute hydrochloric acid as azurite does. It has a Mohs hardness of 2.5 and a specific gravity of 5.3 - 5.5.
Linarite was first identified in 1822. It is named after the Linares Plateau, Spain. It occurs in association with brochantite, anglesite, caledonite, leadhillite, cerussite, malachite and hemimorphite.
