Pset_SolidStratumComposition Properties expressing the composition of a stratum using volume measures, implementing ISO14688 Part 2 Table 1 Primary fractions and composite fractions. Regional and National conventions should be captured through classification and specific property sets. Zero values may be omitted.

BouldersVolume Relative volume of boulders (typically larger than 200mm) stratum constituents. ClayVolume Relative volume of clay (typically smaller than 0.002mm) stratum constituents. CobblesVolume Relative volume of cobbles (typically larger than 63mm) stratum constituents. ContaminantVolume Relative volume of contaminant stratum constituents. FillVolume Relative volume of fill (controlled placement of anthropogenic soil) stratum constituents. GravelVolume Relative volume of gravel (typically larger than 2mm) stratum constituents. OrganicVolume Relative volume of organic (peat/humus) stratum constituents especially soil. RockVolume Relative volume of rock stratum constituents. SandVolume Relative volume of sand (typically smaller than 2mm) stratum constituents. SiltVolume Relative volume of silt (typically smaller than 0.063mm) stratum constituents. WaterVolume Relative volume of water stratum constituents.
