摘要:

A section through the Upper Cambrian alum shales at Hynneberg, Närke, central Sweden, has been investigated chemically and mineralogically. The mineral constituents were examined qualitatively by X-ray and their quantitative distribution was calculated from chemical analyses. The main minerals found were micaceous minerals, pyrite and quartz. The organic fraction was enriched by a flotation process and its composition was found to be almost constant at C10H11O throughout the section. Small amounts of S and N were also found in the organic matter.

摘要:

It is shown that the weathering of a calciferous building sandstone is caused to a great extent by the destruction of the calcite-aggregates of the matrix. The aggregates are destroyed by crystallization from sodium-sulphate present in the sandstone.
