Sandstone layers.

Largest blocks are delivered by thick sandstone and limestone layers and may reach up to 10 m 3. In most of the stretches however, blocks usually range between 1 and 2 m 3. The highest hazard however is due to the failure of rock mass columns which volumes may attain several hundred of cubic metres.Granite changes into sandstone by means of weathering and erosion.

Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...

Sandstone is a sedimentary rock formed from sand-sized mineral particles, while shale is formed from clay or silt-sized particles. Sandstone has a coarser texture and is more porous than shale, with a fine, laminated texture. Shale is more prone to breaking along its layers due to its fine-grained composition, whereas sandstone is more ...

They are the site of very important resources such as ground water, coal, oil, and soil.Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.

is bedding that contains angled layers within otherwise horizontal beds, and it forms when sediments are deposited by flowing water or wind. Some examples are shown in Figures 6.0.11, 6.1.7b, and 6.4.2. Cross-beds formed in streams tend to be on the scale of centimetres to tens of centimetres, while those in. aeolian.
