A multi-station magnetotelluric study in southern Scotland - I. Fieldwork, data analysis and results
A.G. Jones and R. Hutton
Abstract
Magnetotelluric measurements have been made at 13 locations in
southern Scotland along lines perpendicular and parallel to the strike of a
major electrical conductivity anomaly detected by previous geomagnetic deep
sounding studies.
Following a brief account of the fieldwork and data analysis procedure,
the justification for one-dimensional interpretation at certain sites is
presented. Six of the 13 sites fall into this category. Their magnetotelluric
responses were found to fall into three groups which appear to be representative
of (a) the Midland Valley, (b) the Southern Uplands and (c) northern
England. Limited forward modelling of the well-estimated data was undertaken
and is discussed in this paper. It indicates marked lateral variations in
conductivity structure across the region.
