Smith, R.T.; McMillan, A.A.; Bland, D.J.; Fortey, N.J. 1996 Mineral investigations in the Northumberland trough : part 3, Ecclefechan-waterbeck area. Nottingham, UK, British Geological Survey, 53pp. (WF/MR/96/021, Mineral Reconnaissance Programme open file report 21) (Unpublished)
Two of the most important criteria for the formation of major SEDEX Irish-style deposits, the
presence of syn-depositional faulting in a Lower Dinantian basin and a geothermal system over a zone
of high heat flow in the crust, are fulfilled along the northern margin of the Solway-Northumberland
basin. Recognition of the broad similarities in the geological and tectonic history of the sedimentary
basins of east-central Ireland and northern England/southern Scotland prompted Mineral
Reconnaissance Programme (MRP) interest in the Solway-Northumberland basin in the 1970's soon
after discovery of the world-class Navan Zn-Pb deposit in Ireland (Andrew, 1993).
