Barite Crystal Development
At the Monroeville locality, barite has a unique morphology, which often causes the crystals to have a mix of vitreous and crude faces. Discounting the fact that some crystals of barite have been heavily corroded from exposure to the elements of the river, many of the fresher crystals on the inside of septaria have certain naturally rough faces. These rough, rounded, etched or feathered faces make the task of identifying additional modifications nearly impossible. A very few sporadic crystals without distorted faces have also been observed but are not as common. The crude faces are generally an indication of the rate at which the crystalsRead More →
