Geologic Review of Northwestern Arizona for Petroleum Exploration Investigators

INTRODUCTION Northwestern Arizona has a thick section of marine strata which exhibits all the basic geologic requirements for accumulation of petroleum deposits. The structure and lithology of this area are essentially an extension of the geology of the adjacent area of southern Utah, where modest production has been established by relatively limited exploration ac tivi ties. This report presents a geologic overview of northwestern Arizona. Geologic and petroleum exploration data of southwestern Utah are also included to provide information gained by previous exploration activities in a similar geologic setting.
