White Rose Thesis Repository

White Rose Thesis Repository-80
-- The Ben Nevis Formation is a relatively homogeneous sandstone with very subtle changes both petrographically and geochemically.Grouping of similar Zr concentrations within the Ben Nevis Formation has shown three correlatable units throughout the White Rose Field.

I had no particular institution in mind so it was suggested that we could visit the University of Leeds who are one of the partners in White Rose Research Online (WRRO) and White Rose e Theses online repositories (WREO) along with the universities of York and Sheffield.

While admitting they were not especially strong on policies we decided that it would still be a useful visit and it turned out to be a good general exchange of experience.

We discussed both of these in relation to the University of Leeds only.

They do have a mandate for deposit of etheses so students have to provide these, which are received as a disk containing a PDF and accompanying paperwork.

So it was only a short train trip and walk from the city centre before I arrived at the building leading onto the Brotherton Library on 14 October.

I was welcomed by Jodie Double, Digital Content and Repositories Manager, and also met some other members of the team.Staff are generally positive about wanting to make their research more visible, but are often worried about copyright.Where full text is not uploaded there is sometimes just a metadata record included and a link can be made to the publisher version, but this will reduce access to only those people entitled to use it.Firstly, Jodie, Gemma Storr and I spent some time in general discussion.I was interested to hear that WRRO was established in 2004 and includes research outputs for the three institutions and paved the way for the sister service WREO containing etheses from the 3 partners.-- Possible sources with a higher lithic component, such as the Hibernia Formation, imply geochemical alteration with only limited physical reworking of the rock, which removed a large portion of unstable lithic grains and increased the quartz content relative to feldspars and lithic grains, leading to the quartz-rich composition of the Ben Nevis Formation.This process is supported by trace element data and plots of Si O₂ against immobile elements, together with common exposures of Hibernia Formation below the Aptian unconformity.-- The Avalon Formation is petrographically and geochemically similar to the Ben Nevis Formation.Cuttings samples show a similar grain size and chemical composition to the Ben Nevis Formation, indicating that the Avalon Formation is a plausible source for the Ben Nevis Formation without requiring significant reworking or alteration.Average QFL ratios for Ben Nevis sandstones are Q₈₉F₃L₈, with the major lithic components being detrital carbonate grains and chert.Based on subcrop patterns and relative grain sizes, the Tithonian-Berriasian Hibernia Formation sandstones and the Barremian-Aptian Avalon Formation sandstones are thought to be possible sediment sources.
