S. Williams for assistance in the field and to G. A. Cooper for the identification of the Devonian fossils. The Mississippian fossils were identified by J. W. Huddle with the aid of J. S. Williams and Helen Duncan. Well samples and cores were loaned by the Continental Oil Co., the Union Oil Co. of California, the Sinclair Oil Co., the Museum of Northern Arizona, and the Colorado School of Mines.

The rationale for assessment of undiscovered, economically recoverable oil and gas in central and northern Arizona: Play analyses of seven favorable areas

“…into and away from central Arizona, the southwestern end of the TCA. Here the arch is termed Mazatzal Land (ML) by Stoyanow (1942), Huddle and Dobrovolny (1952), and Wilson (1962) among others. The first Paleozoic onlap-offlap sequence deposited beach sand and offshore carbonate and shale contours in feet Nydegger, 1982).…”

“…The following have all recognized the favorable Devonian stratigraphy of the northeastern Arizona-FC area, and hence its potential for major discoveries: Huddle and Dobrovolny (1952), Brown (1956), Brown and Lauth (1957), Turner (1958 and, Pye (1961 and, Turnbow (1961), Lessentine (1965), Conley (1974), Conley and Giardina (1979), Oil and Gas Journal (1979), and Tucker (1983, p. 28-29). Outcrops of the Martin Formation of the MR area are known for their petroliferous or fetid odor in the lower dolomite units (Teichert, 1965) and has led some geologists to consider the Devonian favorable for oil and gas accumulation.…”

Spores and Associated Macrofossils from the Devonian of Arizona

“…Huddle and Dobrovolny (1952) Smooth, flattened, dichotomously-branching axes resembling those of Hostimella, except for the presence of a central vascular strand of tracheids, are referable to the genus Taeniocrada White. Although axes of this type are relatively common at this site, only one specimen-a recurved ultimate portion of an obviously vascularized axis (P1.…”

“…The poor grade and usually interbedded shales, limestones, and quartzites preclude the use of the rock, in most places, as a source of high-purity dolomite. (Huddle and Dobrovolny, 1952;Wilson, 1942) Redwall limestone. The Redwall limestone, of Mississippian age, is predominantly a light-gray to white thin-to very thick-bedded limestone.…”
