Principles of Stratigraphy Stratigraphy is the study of strata (sedimentary layers) in the Earth's crust.Geologist in the 1800s worked out 7 basic principles of stratigraphy that allowed them, and now us, to work out the relative ages of rocks.The goal of this lecture is come to come to a scientific understanding of geologic time and the age of the Earth.In order to do so we will have to understand the following: To better understand these concepts, let's look at an archeological example: Imagine we are a group of archeologists studying two different trash pits recently discovered on the Tulane University campus and at the Audubon Zoo (where they all aksed for you).Other factors and basic assumptions must also be considered.

As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.

For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one."*G. Chesterton (1925)."The theory of evolution gives no answer to the important problem of the origin of life and presents only fallacious solutions to the problem of the nature of evolutive transformations . We are condemned to believe in evolution, but we will always search for a suggestion concerning the methods of transformations . Perhaps we are now in a worse position than in 1859 because we have searched for one century and we have the impression that the various hypotheses [of how evolution could have occurred] are now exhausted.

Presently, nature appears to be more steady, more firm and more refractory [resistant] to changes than we thoughtbefore we had made a clear distinction between hereditary variability [within species] and acquired characteristics [DNA characteristics fixing each species]. Salet, Hasard et Certitude: Le Transformisme devant la Biologie Actuelle (1973), p. Several methods for dating ancient materials have been developed.

His result was in close agreement with his estimate of the age of the earth.

The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction.
