Metal mobility in alum shale from Öland, Sweden
Alum shale is a sedimentary rock belonging to what are termed the 'black shales'. The Swedish occurrences of alum shale were formed during the latter part of the Cambrian era and up to the first part of the Ordovician era, approximately 540–480 million years ago (Hessland and Armands, 1978). 2.1. Composition and metal content of alum …

Alum shale
Alum shales are rocks where most of the constituent minerals originate from the sediments that were once deposited in the sea that covered large parts of Sweden, some 500 million years ago. These minerals consist primarily of clay minerals, fine-grained quartz and feldspar, as well as a small amount of heavy minerals.
