The "Kupferschiefer and Other Sediment-Hosted Deposits in Central Europe" field trip(22 May-1 June 1986), which focussed uponthe stratiform copper shale (Kupferschiefer)deposits of West Germany and Poland, was amajor success. Trip leaders effectively com-municated the stratigraphy associated withthese deposits, the sulphide zonation, andthe controls of mineralization (particularly lo-cation with respect to hematitic alterationzones — "Rote Fàule" — and to paleo-topography). Replacement textures by ox-ides and copper sulphides and cross-cuttingrelationships of ore zones with respect tolithologies indicate diagenetic to epigeneticemplacement of ore. While many crucialquestions have been answered, severalremain.

Lt. Col. Charles Coote Grant (1825-1914) organized the collection and donation of Silurian fossils at Hamilton and Grimsby in Ontario, over a continuous period from 1866 to 1914. He was a competent taxonomist and field geologist, who encouraged visits from professional geologists and wrote useful, if repetitive, papers in the 1889 to 1911 volumes of the Journal and Proceedings of the Hamilton Association. Grant anticipated a 20th-century trend in which field-oriented paleontologists become concerned with deductions from taphonomy and sedimentology.
