Alum Shale Formation - Wikipedia

The Alum Shale Formation (also known as alum schist and alum slate) is a formation of black shale of Middle Cambrian to Tremadocian (Lower Ordovician) in age found predominantly in southern Scandinavia. It is shale or clay slate containing pyrite.Decomposition of pyrite by weathering forms sulfuric acid, which acts on potash and alumina constituents to form alum, which often occurs as,Sweden | Shale & Fracking Tracker | Vinson & Elkins LLP,The Scandinavian Alum Shale underlies large portions of Sweden, Denmark, and potentially Norway. 1 However, a majority of the Alum Shale is “shallow, thin, and immature.” 2 The Alum Shale is normally pressured and is characterized by moderately high clay content and structural complexity, making it a “high risk play.” 3 The Energy Information Administration estimates that the Alum,Estonia & Sweden Oil Shale Deposits | Map, Geology, Resources,The Cambrian and Lower Ordovician Alum Shale of Sweden has been known for more than 350 years. It was a source of potassium aluminum sulfate that was used in the leather tanning industry, for fixing colors in textiles, and as a pharmaceutical astringent. Mining the shales for alum began in 1637 in Skåne.
