"Statistical interpretation of geochemical data was used to determine the environment of deposition of the Maquoketa Formation in Pike County, Missouri. A cyclic sequence was noted which can be best explained by cyclic climatic changes. During the study it was found that elemental relationships which would be expected in a freshly deposited sediment can be found in core samples. In samples from outcrops and quarry faces these relationships have been destroyed. As these elemental relationships reflect mineralogical relationships, serious doubts have arisen as to the validity of petrographic studies of samples taken from outcrops. This study indicates weathering may be responsible for many features which previously have been described as diagenetic--Abstract, page ii.
