Skeletal Quartz from a Field Trip in South Carolina

This quartz gets it's name from it's skeleton-like appearance. According to geologist Mike Streeter, the distinctive pattern is caused by "internal and external dissolution-growth features resulting from unstable conditions during crystallization. At the time that the crystals were forming, the conditions were such that the crystals would alternate between growing and dissolving. This 'two-step forward and one-step backward' process resulted in the unusual step-like appearance."
