Disseminated, isolated fine-grained laths of sphalerite (sph-2) with rare co-crystallising pyrite and galena, within stratabound layers often <1 cm in width. Represents an alteration selvage accompanying early stratabound sphalerite (sph-1). Disseminated sphalerite often splays from pre-mineralisation dolomitic veins and graphitic seams with sph-1.
