A review of the available evidence suggests that the greater part of the New Red Sandstone lavas and sediments of Ayrshire, Sanquhar and Thornhill and probably also part of the \u2018Permian\u2019 rocks of Arran may be Carboniferous. It seems likely that the base of the New Red Sandstone in the Southern Uplands is diachronous, and the basal beds in the Solway Basin and in North-West England may be considerably younger than the New Red Sandstone of Ayrshire.<\/jats:p>\n          <jats:p>The kylitic and teschenitic dolerite sills which cut the Carboniferous sediments of Ayrshire, and the intrusive monchiquites, which are closely associated with the \u2018Permian\u2019 volcanic necks of south-west Ayrshire, are now taken to be of Upper Coal Measures age.<\/jats:p>","DOI":"10.1144\/sjg01010009","type":"journal-article","created":{"date-parts":[[2010,1,15]],"date-time":"2010-01-15T00:29:39Z","timestamp":1263515379000},"page":"9-18","update-policy":"http:\/\/dx.doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["The age of the lower part of the New Red Sandstone of South-West Scotland"],"prefix":"10.1144","volume":"1","author":[{"given":"W.","family":"Mykura","sequence":"first","affiliation":[{"name":"Geological Survey Office, 19 Grange Terrace, Edinburgh 9"}]}],"member":"1881","published-online":{"date-parts":[[2022,4,20]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/1801277a0"},{"key":"e_1_2_2_3_1","first-page":"33","article-title":"Sporological evidence on the boundaries of the stratigraphical subdivisions in the Upper Pennsylvanian strata of Europe and North America","volume":"1","author":"BHARADWAJ D.
