Physical characteristics of siltstoneI want to know some physical characteristics of siltstone, including elastic modulus, Poisson's ratio, P-wave velocityProbably give me a range on the line
Specific just want to know, you can refer to the engineering geology manual fourth edition and the latest engineering geology manual, chapter fifth, chapter 1093, part of the rock elastic modulus comparison table. 2006See page seventhAverage values of elastic modulus of several common rocksMineral Young's modulus (E/GPa) bulk modulus K/Gpa) Poisson's ratioSiltstone 61.64 40 0.23
Detrital siltstone general is relatively simple, mainly quartz, feldspar and lithic rare, sometimes containing more muscovite. In addition to other silt by sand, clay or chemical precipitates. Horizontal bedding often have thin siltstone, sediment water is susceptible to liquefaction induced deformation bedding and other sliding structures. Siltstone divided into coarse siltstone (0.0625 ~ 0.0312mm) and fine siltstone (0.0312 ~ 0.0039mm); according to the mixed composition divided into: argillaceous siltstone, iron siltstone, calcareous siltstone and so on.Elastic modulus, needs to be sent to the laboratory tests in the field sampling, so that it can have in geotechnical engineering. Because each local rock is not the same; is a province with the mudstone, sandstone due to the formation of a different era, there is also a great difference; the other is the same stratum rock structure and water effect is not the same.
The sedimentary rock composed mainly of silty sand is siltstone, the silt content of 0.0625 ~ 0.0039 mm (mm) is a kind of clastic sedimentary rock which is composed of siltstone samples
