Hi there – I need someone to settle an arguement between geologist and engineers. What we need to know is whether or not there is some form of standard for graphical representation of soil types. Is there a WRITTEN standard for graphically representing a sand or a clay. I know what most people use for these but we can't seem to find an ASTM or USGS publication or something similar which gives what exactly these symbols should look like. I appreciate any help you all have to give Steven

Steven, This is probably negative help, but, the USGS _Suggestions to Authors of the Reports of the United States Geological Survey_, Seventh Edition, p.55, simply says: <Standard patterns indicate rock types>. They are discussing the construction of columnar sections for publication by the USGS. My (very old) copy of Robert Compton's _Manual of Field Geology_ has an appendix of suggested patterns but doesn't discuss the origins of these patterns. Good Luck, Jim

Hi, Steven– The ask-a-geologist service that connects to USGS geologists by Internet mail is described in INTERN.TXT in this forum's library. If there is a USGS standard, I would have to guess someone there would know it. I saw a recent assertion in sci.geo.geology that ask-a-geologist is alive and well, apparently in answer to rumors of its demise. –Doug
