Alum shale - SGU
Alum shale is underlying younger bedrock or forms the bedrock surface in parts of Skåne, Västergötland, Östergötland and Närke. The formation is also found on Öland, and as scattered occurrences under thick limestone layers on Gotland. In addition, the formation

Effects of inherent pyrite on hydrocarbon generation by
2022年3月15日 The Alum shale is a well-known source rock for hydrocarbon generation [19], [20]. Besides the high TOC, the Alum shale is rich in large amounts of pyrite [21], [22], which provides an opportunity for exploring the effect of inherent pyrite on the hydrocarbon generation. So, we conducted anhydrous pyrolysis experiments on a low maturity Type
