The Ancient Volcanoes of Great Britain, Volume 2 (of 2)

"The Ancient Volcanoes of Great Britain, Volume 2" by Archibald Geikie is a late 1800s scientific study about old volcanoes in Great Britain, focusing on the Carboniferous and Permian periods. The book examines volcanic formations in the area geologically and historically. It begins by looking at the northern and central areas of England, including the volcanoes from the Carboniferous period, referencing geological events like the Great Whin Sill and the Derbyshire toadstones. The start of the writing introduces the many connections between the different volcanic materials, how old they are, and how they worked with the nearby sedimentary rocks, for further geological studies.
