On behalf of May 28* the executive and directors as well as all of us who June, July, August (no meetings) attended field trips over the years I would like to September 17 thank Les very much for his efforts. Seminars will again be held this year, provided a October 15 meeting area and instructors can be secured. With November 19 the number of new members increasing it may be December 17 timely to repeat past seminars that were held on Curation and Field Methods. If there is interest the Field Trips seminar on Vertebrate Microsites may be held June 19 & 20, 1999 again. If anyone has a particular topic they think July 17 & 18 would make a good seminar please contact me. It August 21 & 22 would also be very helpful if someone would volunteer to coordinate seminars.

    Rank Variation, Coalification Pattern and Coal Quality in the Crowsnest Coalfield, British Columbia

    Rank variation, coalification pattern and coal quality in the Crowsnest coalfield, British Columbia DAVID E. PEARSON David E. Pearson & Associates Ltd. Victoria, British Columbia and DAVID A. GRIEVE British Columbia Ministry of Energy, Mines & Petroleum Resources Fernie, British Columbia ABSTRACT A rank-map of Crowsnest coalfield, showing the distribution of the bituminous coal measures and the locations of major structures, has been produced from vitrinite reflectance measurements on over 560 coalsamples. The timing of coalification in relation to these major structures has also been determined. In the west-central portion of the coalfield a complete stratigraphic succession of coal measures which rides on major thrust surfaces is all of high-volatile bituminous rank, but despite the structural discordance no break in rank is discernible across these structures. The thrust faults therefore predate much of the coalification. Three major valleys expose cross sections of the folded coal measures and in each an increase in vitrinite reflectance is demonstrable as individual seams are tracedfrom ridge crest to valley floor. Thus, in these sections, a significant amount of coalification post-dates folding. The proportion of this post-folding coalification is found to increase toward the south of the coalfield. A late gravity-fault, exposed along the east crop of the coalfield, places high-volatile coal-bearing successions in contact with low-volatile coal and demonstrably is a reactivated thrust fault. Coalification at this locality occurred between these two different ages of faulting. The variations in rank and the subtleties of the coalification pattern have, together with systematic changes in the maceral composition of coal seams, had a profound effect on coal quality in the coalfield.

Total potential in siru coal resources are a minimum of 7.8 billion tonnes. The coal-bearing Mist Mountain Formation ranges from less than 425 to approximately 700 metres in thickness in the study area. An average of approximately IO per cent of its total thickness is composed of coal seams, which range up to 13 metres in thickness.

It is characterized by a relative abundance of coarse elastics (sandstone and locally conglomerate) and lack of coal, in comparison to the underlying Mist Mountain Formation. Problems encountered in identification of the Elk Formation and its contact with the Mist Mountain Formation prompted this study. Stratigraphic sections from five localities in the Fernie basin (Crowsnest coallield) and one from the Flathead coallield were examined and described. Thicknesses of sections are as follows: Coal Creek (type section) - 429.0 metres; Morrissey Ridge north (adjacent to reference section) - 472.7 metres; Morrissey Ridge south - 436.1 metres; Flathead Ridge (“pipeline section”) - 327.0 metres; Lodgepole property - 154.5 metres; and Lillyburt property - 67.1 metres were examined, out of a total Elk Forma- tion thickness of approximately 175 metres.

The spectroscopic detection and bacterial colonisation of synthetic microplastics in coastal marine sediments Jesse Patrick Harrison Department of Animal and Plant Sciences, The University of Sheffield Submitted for the degree of Doctor of Philosophy April 2012 Abstract Synthetic microplastics ( ≤ 5-mm fragments) are anthropogenic contaminants that are rapidly accumulating in coastal environments worldwide. The distribution, abundance, ecological impacts and fate of these pollutants are poorly understood. In this study, a novel reflectance micro-FT-IR spectroscopy method was developed to detect microplastics in sediments from 17 sites (UK), using polyethylene (PE) as the model polymer. Additionally, a 14-day laboratory microcosm experiment was used to characterise bacterial succession on low-density polyethylene (LDPE) fragments over time and across three sediment types (ranging from sand to silt) from the Humber Estuary, UK. In contrast with ATR-FT-IR measurements, micro-FT-IR measurements in reflectance mode were susceptible to refractive error when analysing irregularly shaped PE fragments. However, molecular mapping by reflectance micro-FT-IR spectroscopy successfully detected PE within polymer-spiked sediments and in a non- spiked sediment retentate.
