This new, fully revised, 5th edition of the "Northern England 'Regional Geology' Guide" describes the wide variety of rocks, with a geological history spanning almost 500 million years, which underlie Northumberland and Durham, the English Lake District and the Isle of Man. The Lake District and Northumberland National Parks form substantial parts of the area described, whilst the Yorkshire Dales N.P., overlaps its southern margin. Recognised Areas of Outstanding Natural Beauty include the Northumberland Coast, the Solway Coast, and the North Pennines, the last of these areas also being designated a UNESCO European and Global Geopark. Written for geologists, students and anyone interested in the latest interpretations of the geology of the region.
