Wavellite crystals on matrix - Těškov quarry, Těškov, Rokycany District, Plzeň Region, Czech Republic
Wavellite is a rare phosphate secondary mineral that crystallises as radiating 'starburst' clusters of fibrous crystals.
A secondary mineral is a mineral that occurs as a by-product of weathering. It does not form on its own and is dependent on the formation of primary minerals + specific weathering conditions.
It is named after Dr. William Wavell, a physician, botanist, historian, and naturalist in Harwood Parish, Devonshire, England, who discovered the mineral.
Interestingly, there are only 300 inhabitants in the Těškov village. The Těškov quarry, however, is rich in 29 different minerals. So, this village is one of those small, old villages that is very dependent on the mining industry.
