The central part of the vein is characterised by a prominent northeast-trending strike-slip fault continuing into the immediately overlying limestone caprock with en echelon carbonate-filled tension gashes displayed along its plane.
Blocks of limestone exhibit tilting and collapse towards the central fracture, and mosaic breccias with abundant large cavities are well-developed adjacent to either side of the main fracture core, becoming smaller and "ribbon"-shaped towards the periphery of the breccia.
Often, the distinction between vein and pockets is blurred along the sinuous Bull Vein. It is characterised by sudden changes in the colour and zonation of the fluorite, sometimes with a sufficient number of specimens to warrant a specific pocket name, and where this is not the case, specimens are recorded simply as "The Bull Vein".
Yellow fluorite is a good example, where distinct pockets have been named Sherry Twins, Harvest and Lemon Meringue, with all other variable yellows assigned "The Bull Vein".
Green fluorite occurs in the Poison Ivy, Toxic Apple and Minty Cheesecake pockets.
