Historical Geology Introduction
Inductive reasoning Interpretation of ancient
causes from observable historical results

Historical Geology Introduction
No equation for mountains. No formula for
extinction of dinosaurs. Historical Geology is
like CSI.

Historical GeologyInterpretive Science
Historical Geology Introduction
Based on observations (clues) and
your knowledge of physical geology and
biological concepts
21
Historical GeologyInterpretive Science
Historical Geology Introduction
you reconstruct a sequence of events that
occurred over geologic time then develop an
explanation of events that account for object
you are studying.

note inductive reasoning does not
absolve us from quantification
23
Fields of Geology
Historical Geology Introduction
Petrology study of the formation of rocks.
Sedimentary, Igneous, Metamorphic.
Sedimentology environments, depositional
process rocks. Stratigraphy relationships of
strata in time and space. Structural Geology
how rocks are deformed during stress.
Mountain building and Plate
Tectonics. Paleontology study of ancient life.
24
Fields of Geology
Historical Geology Introduction
Geochemistry Geophysics application of
chemistry and physics to the study of
the earth. Field Geology application of all to
the interpretation of rocks "in the wild".
