Uinta-Piceance Basin stratigraphic column showing the relationship of the Phosphoria Formation
The Phosphoria Formation of the western United States is a geological formation of Early Permian age.[4] It represents some 15 million years of sedimentation, reaches a thickness of 420 metres (1,380 ft) and covers an area of 350,000 square kilometres (140,000 sq mi).[1]
The Phosphoria includes phosphorite beds that are an important source of phosphorus.[5] Many of its shales are rich in organic matter and are petroleum source rocks,[6] and some of its dolomites include petroleum reservoirs.[7]
