Enhance your ability to think on your feet and refine your observational skills in sedimentary analysis and improve your log accuracy: •Enhance your soil and sediment descriptions •Prepare consistent descriptions and meaningful boring logs •Accurately classify soil in the field using the USCS •Analyze sedimentary data as the drilling program progresses •Characterize stratigraphic successions in the field •Build the geologic framework from boring to boring •Reduce editing time Soil descriptions have never been easier when you use the Field Guide's flow chart listing key descriptive elements for characterizing sedimentary sequences on boring logs. Common terms from geologic, engineering, and soil science disciplines are used on the Field Guide to help prepare meaningful boring logs that are clear and concise. The back side of the Field Guide includes a easy-to-use flow chart that takes the mystery out of using the Unified Soil Classification System and assigning a group name and USCS symbol in the field.
