Where did scientists create a geologic column?

Answer 1

The first geology map, of England, Wales and part of Scotland, was made in 1799 by William Smith (English, 1969 - 1839), though sadly his relatively humble background and lack of the right connections meant he was ignored personally but his work plagiarised by contemporary geologists to the extent that he became bankrupt - an imprisonable offence at the time.

Smith already knew how to produce stratigraphical columns as a canal and coal-field surveyor, but he was the pioneer of the Principle of Faunal Succession -used in stratigraphical relative-dating and correlation as well as the palaeontology itself. He realised he could produce geological map plans based on the colour-coding principle of an existing map he saw of soil and vegetation types.

Since then the principles he used have been employed by geologists around the world in producing geology maps and the corresponding sections, stratigraphical columns and correlation-diagrams.

Answer 2

It is an imaginary column where are the ages of rocks sit on top of one another in their proper age sequence, oldest at the base and youngest at the top. An ideal sequence of rock layers that contains all the known fossils and rocks whith each sequence is given its name.

Answer 3

Scientists created the geologic column based on studying rock layers around the world, particularly in places like the Grand Canyon in the United States and the cliffs of Dover in the United Kingdom. By observing the sequence of rock formations and the fossils found in each layer, scientists were able to piece together the history of Earth's geology.
