Figure F29. Stratigraphic cross-section of Brazos-Trinity Basin #4. The core and well logs are datumed at sea level. Stratigraphic ties between sites are based on seismic, lithology, log signature, and biostratigraphy. Each column contains a depth scale, a schematic lithology, gamma ray (GR) and resistivity logs (from LWD), and the depth of key seismic surfaces. In the core recovery diagram, black = cored, red = overlap due to core expansion, and white = no recovery.
