Geology (from Greek γη- (ge-, the earth) and λογος (logos, word, reason)) is the science and study of the Earth, its composition, structure, physical properties, history, and the processes that shape it. ...

Born at Faringdon, Berkshire, and trained as a teacher, Lapworth settled in the Scottish border region, where he investigated the previously little-known fossil fauna of the area. He married in 1869 and stayed in the area. Eventually, through patient mapping and innovative use of index fossil analysis, Lapworth showed that what was thought to be a thick sequence of Silurian rocks was in fact a much thinner series of rocks repeated by faulting and folding.

The Silurian is a major division of the geologic timescale that extends from the end of the Ordovician period, about 439 million years ago (mega years ago, mya), to the beginning of the Devonian period, about 408. ...

Eventually his controversial analysis was accepted, and he slowly rose to become one of the leading geologists in the British Isles. He served as a professor at several colleges, and received numerous awards for his work. He is best known for pioneering faunal analysis of Silurian beds by means of index fossils, and his proposal (eventually adopted) that the beds between the Cambrian beds of north Wales and the Silurian beds of South Wales should be assigned to a new geological period—the Ordovician. This proposal resolved a heated argument over the age of the strata in question. The British Isles consist of Great Britain, Ireland and a number of much smaller surrounding islands. ...
