Stratigraphy

Stratigraphy is a branch of geology which studies rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy includes two related subfields: lithologic stratigraphy or lithostratigraphy, and biologic stratigraphy or bio…

Uniformitarianism

Uniformitarianism was an assumption that the same natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere in the universe. It has included the gradualistic concept that "the present is the key to the past" and is fun…

, relies on the recognition of partial sequences in different areas (Figures 1.3 and 1.5). Characteristic lithologies or fossils permit us to assemble the different partial columns from different regions.

What is correlation in geology?

  • In geology, the term correlation refers to the methods by which the age relationship between various strata of Earth's crust is established. Such relationships can be established, in general, in one of two ways: by comparing the physical characteristics of strata with each other (physical correlation); and by comparing the type of fossils found in various strata (fossil correlation).

What is the definition of correlation in science?

  • Correlations in Science. A correlation of -1 says that the two variables are inversely related. As one variable increases the other always decreases. For example, the total sales in a given day for an ice cream truck and the total snowfall for that same day might have a correlation close to -1.
