Fig. 8. Formation Microimager log showing clast size and bedding characteristics of older fanglomerate deposits in Well R-6. Two representative depth intervals are shown (351.7–357.5 m, 1154–1173 ft and 388.6–395.9 m, 1275–1299 ft). The older fanglomerate is a coarse-grained deposit with thick cobble and gravel beds separated by well-stratified sandstones. During logging, four sensors pads in contact with the borehole wall produce oriented, high-resolution resistivity maps. Resistive dacite cobbles and gravels are indicated by lighter colors, and conductive clay-rich beds and water-bearing zones are indicated by darker colors. Thin black horizontal lines indicate bedding planes used to determine bedding orientations.
