The Læså Formation is a lower Cambrian unit exposed on the Baltic island Bornholm, comprising two members: the lower, the Broens Odde Member, colloquially and previously informally termed "green shales" (Grønne Skifre), a 100 m thick glauconitic silt-sandstone occasionally bearing extremely acritarch-rich phosphatic pebbles;[1] gradually transitioning upwards into the upper, the 3 m thick Rispebjerg Member, a sandstone.[2]
