Staurolite Porphyroblasts

metmins-hs_001.Brown staurolite and blue-gray kyanite porphyroblasts are weathered in relief in in this photograph of a Gassetts schist outcrop near Ludlow, VT, USA. The larger staurolite crystals are about 2 cm long.



Lawsonite Pseudomorph photo

metmins-hs_002. Euhedral, white lawsonite crystals grew in this glaucophane schist from northwestern Syros, Greece. Although in most cases the lawsonite has been replaced by a very fine-grained mixture of other minerals, the euhedral shape of the original lawsonite remains as a pseudomorph. One Euro coin for scale.



Wollastonite Skarn Photo
