text: The characteristics that suggest formation of selenite crystals in the bed by recrystallization are: (1) obscurity of boundaries of some adjacent selenite crystals; (2) interfingering of shale and selenite, optical continuity of some selenite being maintained around the shale; (3) optical continuity between satin spar crystals in a veinlet and the selenite of the vein walls; (4) optical continuity between the satin spar layer along the upper contact and crystals of selenite below the contact; and (5) inclusion of small gypsum crystals within the boundaries of some selenite crystals.
