Research

  • HILDENLEY LIMESTONE (click on link for full details of project)
    • To set up a database for examples of Hildenley Limestone found during other survey work.
    • High Status (Late Jurassic) limestone used/reused from pre-Roman(?) to late C19.
    • Odd blocks are being recorded in buildings many kilometres away from quarries.
    • Depositional origins still not understood but top may be equivalent to Coral Rag.
    • Research work on 'chalk-like' figurines at Hull Museum underway to identify rock type.
    • Recorded from High Status buildings by its absence, ie plundered and moved on.

  • LICHEN STUDY
    For some time now, it has been apparent that there appears to be a correlation between church building stones and lichen cover. Notes from a preliminary meeting are available here.
    • To relate lichen cover to specific rock groups.
    • To relate lichen species to rock groups.
    • To produce a rock identification chart for potential non-geologists using lichen cover (not species identification).

  • CHURCH BUILDING STONES
    • To survey churches within defined geographical areas as:
      - Central Yorkshire Wolds
      - Holderness
      - Howardian Hills
      - Northern scarp from Malton to Flamborough Head
      - Western scarp of the Yorkshire Wolds from Malton to the River Humber
    • To record building stone(s) used in the construction of named churches.
    • To build a resource base for named churches, stored electronically and as printed/photograph records, including information available from written records or on web sites.
    • To relate the age of the named church to the building stone(s) used.
    • To relate the use and reuse of stone to local and distant quarries.
    • To record churches associated with large estates and the 'import' of building stones from other areas of Britain and Europe.
    • To relate (where possible) the reuse of stone from archaeological sites.
    • To advice on suitable replacement stone(s) for repairs.
    • To promote the educational value of churches.

  • MOWTHORPE QUARRIES/SHERIFF HUTTON CASTLE
    • Archaeological, Geological and Historical research into the Castle and Source Quarries
    • Working with BGS on 'Lake Mowthorpe' and historical records as to transport of stone
    • Recent field work on bloomery sites (Medieval?) that used local Mid Jurassic coals and ironstones from Cleveland Ironstone/Staithes Sandstone Members (Middle Lias)
    • Field Walking has recovered Mesolithic flints and unidentified pottery shards
    • DMV at Birkdale Farm may be artisan working site (?)
    • Building Stone from quarries looks like Dogger but fauna is more like Whitwell Oolite!
    • Possible channel deposits cutting through Dogger during deposition of Whitwell Oolite?
    • Similar channels recently seen cutting into Dogger in Bilsdale

  • BRANDSBY ROADSTONE/SLATE
    • Surveys of quarries, walls and roofing 'slates'.
    • Both High and Low Status used/reused throughout history from medieval times to C19
    • Unique facies of the Scarborough Formation (Mid Jurassic)
    • Recorded by its absence from High Status Sites
    • Very few buildings are roofed in 'slates' often being replaced by tiles or West Riding(?) flags
    • Few examples found away from main quarry sites (now overgrown)

  • ROCK/FOSSIL COLLECTION
    • To collect samples for the Group and other interested organisations.

  • ROCK/FOSSIL COLLECTIONS HELD AT LOCAL MUSEUMS
    • To visit local museums to find historically recorded collections referenced to local geology, history and building stones.

  • VILLAGE/BUILDING SURVEYS
    • To select individual buildings or whole villages and circulate members to assist with survey using maps and historical data.
