Sections are of great importance in geology, as it is largely by their aid that the relations and positions of the various members of the different formations. both stratified and unstratified, are made intelligible. The geological structure of any region is best indicated by one or more cross-sections on which the groups of rocks are represented in the order in which they occur and with the proper dips, as well as the irregularities due to faults, crust-movements, and invasions by igneous masses, by which causes the stratigraphy of a region may be made so complicated and obscure as to be unintelligible without such assistance to its comprehension as is afforded by cross-sections.
