DESCRIPTION OF FORMATIONS.

In describing the formations in this report, a detailed
citation of the localities where they occur is not given in the
text, as these can be more readily got from the maps. The
places mentioned are those that are important as type localities
or for other reasons. A comprehensive summary of the main
rock types found in each formation is given here, and detailed
descriptions will be found in the chapter on ‘‘Petrography.”’
