1. 3D Geological Modelling of the Subsurface Adjacent to Cementa’s Quarry in Skövde, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Limestone is one of the main components of cement production. Limestone has been quarried in Skövde, Sweden, since the end of 19th century and Cementa AB has been operating the quarry since 1973. Aside from limestone, there are also Alum shale of Cambrian age, mudstones as well as bentonite layers of Ordovician age present in the quarry. LÄS MER

3. Aluntillverkningens betydelse för skogen : med ett exempel från Andrarums alunbruk i Skåne 1637–1912
Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskapSammanfattning : Andrarums alunbruk satte stort avtryck i den omgivande skogen. Bruket krävde stora resurser av ved för att kunna processa alunskiffer till alun, vilket gjorde att behovet av vedresurser var stort. LÄS MER
4. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle
Kandidat-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER
