Microtektite-like glass spherules in Late Devonian (367 MA) shalesGlass spherules are found closely associated with the Frasnian-Famennain (FF) boundary in two sections, Senzeille and Hony, located in the Dinant basin in the South of Belgium. These spherules are interpreted, based on their chemistry and low water content, as impact produced microtektite-like glass. Craters of Late Devonian ages include the Siljan Ring (Sweden), Charlevoix (Quebec), and Taihu Lake (China). The occurrence of microtektite-like glass closely associated with the FF mass extinction is intriguing. The relationships between the impact and the extinction event deserve further study.
