This report presents the results of an investigation to (1) define the lithologic character and subsurface distribution of hydrogeologic units in the Durham Triassic basin, North Carolina, (2) identify and describe specific properties of rocks in the basin, and (3) describe water quality and circulation of ground water in the basin. These objectives were accomplished primarily by borehole-geophysical and laboratory analyses of rock and aquifer properties.
Although the study area encompasses the entire Durham Triassic basin of North Carolina, most geophysical and physical properties analyses were made from logs and cores of the Sears No. 1 test well, located east of the Wake County-Chatham County line in the central part of the basin.
Includes 45"x36" geophysical log chart of the Sears No. 1 well and laterolog of the Groce No. 1 well. By Charles E. Brown, 1988. 29 pages.
