Barytes and celestite in the sedimentary rocks of Sweden
in the alum shale of Sweden but as early as 1826 HisiNGER (p. 216) published an analysis of barytes from the alum shale at Andrarum in Scania. It was not, however, the small, free crystals that he analysed but a concretionary aggregate of the type known already at .

Alum shale | Wiki | Everipedia
Alum shale's wiki: 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 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 ...
Environmental impact from shale waste deposits in Sweden ...
the fact that shales both from Sweden and Estonia have been used for production of hydrocarbons the remaining waste behaves very differently. Two waste piles have been compared; one in Sweden (Kvarntorpshögen, 28 Mton, black alum shale, 18% kerogen [1]) and one in Estonia (Kukruse, Mton, kukersite, 1065% kerogen [2]).

Jul 20, 2011· Although the exact resource potential in Sweden's Alum Shale is unknown, there could be trillion cm of recoverable shale gas, according to a 2009 report by Advanced Resources International consultancy. The US Energy Information Administration puts the country's recoverable shalegas resources at 12 trillion cf.
Olenus Ctenocephalus Trilobites from Sweden
Jul 27, 2013· From my exchanges with my friend Christian in France, here are some Trilobite fossils that he collected in Sweden. First up are a couple of black shale pieces that have partial cephalon pieces from two species of Trilobites: Ctenocephalus exsulans and Bailiella impressa Cambrian Brantevik, Sweden
Mobility of trace elements in black shale assessed by ...
ABSTRACT This study focuses on the abundance and mobility of Ca, Fe, S and trace elements (As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, U, V and Zn) in black shale (alum shale) in SE Sweden. Samples of nonweathered, weathered and burnt black shale were chemically characterized and the potential element release from them was assessed by standard waterbased leaching tests and pH/redoxregulated ...
Uranium in Sweden Nuclear Heritage
Uranium in Sweden. There are huge amounts of low grade uranium in Sweden both in old bedrocks and younger black shales (alum shale). Most of the black shale uranium is in the south part of Sweden, most of the bedrock uranium is the north. As part of the former plans for nuclear weapons in Sweden a uranium mine was established in black shale in...

Irradiation of organic matter by uranium decay in the Alum ...
Abstract The Alum Shale of Sweden contains black shales with anomalously high uranium concentrations in excess of 100 ppm. Syngenetic or early diagenetic origin of this uranium indicates that organic matter within these shales has been irradiated by decaying uranium for approximately 500 Ma.
