Thomas Belt FGS (1832 – 21 September 1878), an English geologist and naturalist, was born at Newcastle-on-Tyne in 1832, and educated in that city.
As a youth Belt became actively interested in natural history through the Tyneside Naturalists' Field Club.
Later on he was engaged for about three years at Dolgelly, another though small gold-mining region, and here he carefully investigated the rocks and fossils of the Lingula Flags, his observations being published in an important and now classic memoir in the Geological Magazine for 1867.
Henry Walter Bates gave assistance and supervised the book's printing by the publishing house J. Murray.
[4] In subsequent papers Belt dealt boldly with the phenomena of the glacial period in Britain and in various parts of the world.
