NOT SRMs

NOT SRMs
Franciscan Complex melange at Calaveras Dam spillway excavation, California (2014)
Franciscan Complex melange at Calaveras Dam spillway excavation, California (2014)
Melange required blasting because of large, resistant blocks. Uniform gray color for most of slope in shotcrete but large blocks left as-is. (Photo E. Medley, 2014)
Aromas Quarry in San Andreas Fault Zone (E Medley, 2006)
Aromas Quarry in San Andreas Fault Zone (E Medley, 2006)
Granitoid rock sheared by >300 km of movement along the San Andreas Fault to form a bimrock composed of large to small blocks strong enough to crush for aggregate popular in the San Francisco Bay Area.

Colluvium at Hwy I near Big Sur, California (E Medley, 2010)
Colluvium exposed at a road cut at Hwy 1 at Big Sur coast, south of Carmel, California. This material is similar to materials described as SRMs (soil-Rock Mixtures) in the literature. Photo: E. Medley, 2010
Excavated slope of glacio-fluvial deposits, N. Italy
Excavated slope of glacio-fluvial deposits, N. Italy
Glacio-fluvial deposits exposed at a quarry beside the railway line between Locarno, Switzerland and Domodossala, Italy. At the scale of the whole slope the majority of boulders are not geotechnically significant; at excavation equipment scale they are troublesome. At lab-scale the material will be very awkward to work with as is typical of bimsoils.
Alluvium between Domodossala and Locarno (E MEdley, 2019)
Alluvium between Domodossala and Locarno (E MEdley, 2019)
Alluvium beside railway line between Locarno (Switzerland) and Domodossola (Italy). The bim material is troublesome at the scale of an hydraulic excavator bucket. Blocks here are large enough to require jack-hammering to render them manageable for handling. Photo: E Medley, 2019.
Alluvium near Carmel, California  1990 E Medley
Alluvium near Carmel, California 1990 E Medley
Alluvium at this scale is a bimsoil - troublesome at lab-scale, awkward at the scale of a hand shovel, but not a problem for a hydraulic excavator or bulldozer. At the scale of a 30 m high slope (100 feet) this material is not a bimsoil. Photo: E Medley, 1990
