Kupferschiefer and Other Sediment-Hosted Deposits in Central Europe: Field Trip Review

The "Kupferschiefer and Other Sediment-Hosted Deposits in Central Europe" field trip (22 May-1 June 1986), which focussed upon the stratiform copper shale (Kupferschiefer) deposits of West Germany and Poland, was a major success. Trip leaders effectively communicated the stratigraphy associated with these deposits, the sulphide zonation, and the controls of mineralization (particularly location with respect to hematitic alteration zones — "Rote Fäule" — and to paleotopography). Replacement textures by oxides and copper sulphides and cross-cutting relationships of ore zones with respect to lithologies indicate diagenetic to epigenetic emplacement of ore. While many crucial questions have been answered, several remain
