Geology and Petroleum Geology

I always love geology. In winter, particularly, it is pleasant to listen to theories about the great mountains one visited in the summer; or about the Flood or volcanoes; about great catastrophes or about blisters; above all about fossils … Everywhere there are hypotheses, but nowhere truths; many workmen, but no experts; priests, but no God. In these circumstances each man can bring his hypothesis like a candle to a burning altar, and on seeing his candle lit declare ‘Smoke for smoke, sir, mine is better than yours’. It is precisely for this reason that I love geology.

All geologic history is full of the beginning and the ends of species–of their first and last days; but it exhibits no genealogies of development.

Geology may be defined to be that branch of natural history which investigates the successive changes that have taken place in the organic and inorganic kingdoms of nature. It is a science founded on exact observation and careful induction; it may termed the physical history of our globe; it investigates the structure of the planet on which we live and explains the character and causes of the various changes in the organic and inorganic kingdoms of nature.
