Summary:The Marl Slate (the English equivalent of the Kupferschiefer) is a bituminous dolomitic laminate. Unweathered sequences show variations in inclination directions of the magnetization as well as a change in inclination from negative to positive polarity. Direct precipitation of CaCO3 and CaSO4 was associated with the introduction of detrital quartz, clay minerals, organic materials, and oxides; the early CaCO3 underwent penecontemporaneous dolomitization, and a later diagenesis caused the breakdown of CaSO4 to be replaced by length-slow chalcedony, crystalline dolomite, and sulphides. The latter include not only framboidal pyrite but also sulphides of Cu, Fe, Zn, and Pb, their sulphur having been derived from the replacement of CaSO4. [R.A.H.]
