Queen's Hill Formation

Computer Code: QH Preferred Map Code: SYMB
Status Code: Full
Age range: Neoproterozoic Era (AZ) — Neoproterozoic Era (AZ)
Lithological Description: Mixed psammite, semipelite and pelite, with rare beds of calc-silicate rock.In the Balnagowan Hill - Queen's Hill area, discrete units of psammite and pelite can be mapped out.
Definition of Lower Boundary: On Sheet 65E, top of Balnacraig Metabasite Formation (Easdale Subgroup); not seen on sheets 66W, 66E, 76W and 76E.
Definition of Upper Boundary: Incoming of dominantly calcareous material at the base of the Deeside Limestone Formation (Sheet 66W) / Water of Tanar Limestone Formation (Sheet 65E) (Tayvallich Subgroup).
Thickness: Approximately 1700m in northern Sheet 65E, but this may be an overestimate, due to tectonic thickening.
Geographical Limits: Forms a 4-6km wide strip on Sheet 65E from Gallows Hillock (NO295 797) to Pannanich Hill (NO390 950), and a belt up to 6km wide on Mid-Deeside (Sheets 66W, 66E, 76W, 76E) from near Tombae (NO425 970) at least as far as Banchory (NO695 953).
Parent Unit: Crinan Subgroup (DBCN)
