Grey complex dolomite crystals with a single brownish cerussite crystal from the Kintore open cut, Broken Hill. In addition, there are tufts of an unknown white mineral. Candidates could be sepiolite (not recorded at Broken Hill) or palygorskite (recorded, but as a different habit, and rare). Maybe something else. It needs to be analysed.
