Historical geology. Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [ 1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth, gradual and sudden, over this deep time.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers ( stratigraphy ). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
There followed a period of 20 years during which the theory of continental drift developed from being believed by a few to being the cornerstone of modern geology. Beginning in 1947 research provided new evidence about the ocean floor, and in 1960 Bruce C. Heezen published the concept of mid-ocean ridges.
The Geographical Journal. 14 (5): 481–504. doi: 10.2307/1774538. JSTOR 1774538. In his 1899 publication William Morris Davis outlines in detail the cycle of erosion model laying the foundations for the study of peneplains, relief development and denudation chronology. Łozinski, W. (1912).
Principles. The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [ 5] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
Sequence stratigraphy is a branch of geology, specifically a branch of stratigraphy, that attempts to discern and understand historic geology through time by subdividing and linking sedimentary deposits into unconformity bounded units on a variety of scales. The essence of the method is mapping of strata based on identification of surfaces ...
In 1951, Woodford published a geology textbook with James Gilluly and Aaron C. Waters, Principles of Geology, which became the standard instruction for the subject. He published a history of the field, Historical Geology, in 1965. Personal life. Woodford married Gwendolyn Green in 1929, a partnership that lasted until her death in 1982.
Historical geography is the branch of geography that studies the ways in which geographic phenomena have changed over time. [1] In its modern form, it is a synthesizing discipline which shares both topical and methodological similarities with history , anthropology , ecology , geology , environmental studies , literary studies , and other fields.
