... The igneous rocks of north-east England The area of north-east England, east of the Pennines and between the Scottish border to the north and Teesside to the south has a variety of igneous rocks of different ages, and in this essay I will try to describe the major types that are found, concentrating on the Whin Sill, the Cheviots, and the Weardale Granite in particular, but also commenting on other igneous rocks of the region. I have included a map of the area to show the main bands of igneous rock. The main igneous rock of the north-east is the Great Whin Sill, the largest hypabyssal intrusion in Britain which was intruded approximately 295 million years ago. As the name suggests, it is an example of a common concordant intrusion known as a sill, and the whole Whin Sill complex is a number of lenses of differing thicknesses linked together at depth.
