Is shale brittle
Witryna13 kwi 2024 · The shale samples used in this study were examined by X-ray diffraction to determine their mineral composition, and the results are shown in Table 1. Among them, quartz, as a brittle mineral, has the highest content, and the clay mineral is illite. Witryna10 kwi 2024 · It can be seen that the order of their brittleness from weak to strong is: shale, granite, sandstone, and marble. This order is consistent with the fragmentation effect and efficiency of these types of rocks under the impact load, indicating that the percussive drilling is more suitable for brittle stones. Brittleness is an essential …

Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers … Zobacz więcej Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding planes. … Zobacz więcej The fine particles that compose shale can remain suspended in water long after the larger particles of sand have been deposited.
