Stratigraphy, Lithology, And Depositional Environment Of The Black Prince Formation Southeastern Arizona And Southwestern New Mexico, Patrick Kevin Spencer
WWU Graduate School Collection
The Black Prince Formation (new manuscript name) of southeastern Arizona and southwestern New Mexico is subdivided into four lithologic facies representing four environments of deposition. The first lithofacies consists of the basal member of the type section of the Black Prince Limestone and is a result of erosion and reworking of the underlying Escabrosa Limestone. The three limestone lithofacies suggest deposition on a shallow shelf under supratidal, intertidal and subtidal conditions. Cyclic fluctuations in sea level are seen in the rock record in the vertical alternation of lithofacies. Six unconformities are recognized and these are traceable throughout the region.
