Numerous mineral species and unique mineral assemblages are associated with habitats where Acarospora sinopica and other 'metal-loving' lichens occur. This image shows "Halotrichite" [FeAl2(SO4)4· 22H2O], only found so far on shales on the surface. Magnifying glass is 85mm long. Parys Copper Mine, Amlwch, Anglesey, Wales. 20 March 2008.
