The outcrops are located in the northern Adana Basin, near Karaisali village, 40 km (25 mi) from Adana city, Turkey (Figures 1, 2). During the Miocene, the Adana Basin was part of a foreland or forearc basin (Kelling et al., 1987). Sediment was eroded from the tectonically active Tauride Mountains to the north, and a thick package of predominantly deep- and shallow-marine sediments were deposited in the basin to the south. The Miocene (Burdigalian to Serravallian) deep-water clastics of the Cingöz Formation are the focus of this study.
In the western areas of the basin (Figure 2), a 9-km (5.6-mi)-long and 3–4-km (1.9–2.5-mi)-wide, asymmetric canyon is exposed. The canyon fill is sand-rich and composed of amalgamated beds that extend across its entire width (Figure 3). The beds are arranged into 15–20-m (50–66-ft)-thick packages of generally fining- and thinning-upward beds. The base of each package is generally erosive and composed of multiple channels (Figures 5, 6). Lateral to the canyon, thin-bedded sandstone and shales persist for several kilometers (miles), gradually passing laterally into homogenous basin-floor siltstones (Figure 8).
In the eastern areas (Figure 2), a feeder channel with its four tributary channels is exposed (Figure 11). These channels are an order of magnitude smaller than the canyon in the west. The channel fill is predominantly conglomerate-rich and composed of erosive and tabular turbidite beds with intervals of muddy debrite and hemipelagic shale beds (Figure 12).

Tor H. Nilsen, a red-haired Scandinavian who stood more than six feet tall, died October 9, 2005, at his San Carlos, California, home. This was after a valiant five-year fight with melanoma cancer. He was 63. His ashes were scattered at his family plot in Norway in 2006.
He was born in New York City on November 29, 1941, to Mollie Abrahamson and Nils Marius Nilsen of Mandal, Norway, and was the first of their children to be born in the United States. After graduating from Brooklyn Tech, he earned his B.S. in geology from City College of New York in 1962. While there, his prowess on the basketball court impressed a scout from the New York Knicks, but Tor went on to graduate school and earned his M.S. and Ph.D. degrees in geology from the University of Wisconsin at Madison in 1964 and 1967, respectively. His M.S. thesis was a study of Precambrian metasedimentary deposits in the Lake Superior area, and his Ph.D. thesis was a study of Devonian alluvial-fan deposits of the Old Red Sandstone in western Norway.
Dr. Nilsen’s principal expertise was in depositional systems analysis, stratigraphic analysis, and the relationships among tectonics, eustasy, and sedimentation. He began his industry career in 1967 as a research geologist with the Shell Development Company in Houston, Texas, and Ventura, California, where he worked on the tectonics and sedimentation of Tertiary shelf systems of coastal California. He subsequently spent two years with the U.S. Army Corps of Engineers as the Military
