Same and same- same apparent soil unit and same geologic formation (though samples are still to be considered unconsolidated seds). Little to no- and definitely with no obvious pattern- visual variation; dark gray to blue gray, occasional fine to very fine sand micro-lenses. I mentioned depth...
Approximately thirty data points, reruns are in progress. To explain a bit better: the data is from depths of 80 to 200 feet below ground surface on the North Slope of Alaska, possibly (likely?) within the Skull Cliff Member of the Gubik Formation. Individual samples are from a total of 34...
Is it possible to have that range of plasticity from an otherwise homogenous clay source? I'm talking range of plasticity index from less than 10 to nearly 80, and range of liquid limit from 30 to greater than 100. Is there a method of deposition, mineralogy, or chemistry that could explain...
Are we the only ones who call it an MA? I think among ourselves here we've decided that it must be a quirk of the boss. We are in agreement that MA does refer to 'Mechanical Analysis', but that Mechanical Analysis is understood to include both the sieve analysis and sedimentation, not just the...
We are having an interoffice debate over the origin of the test request designation of MA for hydrometer analysis. In our own lab we have SA for sieve analysis, and MA for hydro. Most think that the M is for mechanical, but that applies to the sieve, too. How about mass? Or is the M from the...
