RT Journal Article SR Electronic T1 Contoured patterns of the throw and hade of normal faults in the Coal Measures (Westphalian) of north-east Derbyshire JF Proceedings of the Yorkshire Geological Society FD Geological Society of London SP 147 OP 161 DO 10.1144/pygs.45.3.147 VO 45 IS 3 A1 RIPPON, J. H. YR 1984 UL http://pygs.lyellcollection.org/content/45/3/147.abstract AB Good documentation of uncomplicated tectonic faulting in the Coal Measures of north-east Derbyshire has enabled fault planes and zones to be isolated for detailed study, both laterally and vertically. Systematic variations in throw and hade are revealed by contouring the fault planes for these properties, and typical patterns are described. The individuality shown by faults is emphasised.
