WebRock diameter is likely to be approximately 1.5m: assuming rock depression into subsoil to a third of its depth i.e. 0.5m, the localised elongation in the geotextile due to surface friction between the subsoil and rough edges of the rock could be as much as 20%. To allow a FOS=3, a minimum tensile extension would therefore be 60%. Web1. When preexisting rocks are buried deep underground, they’re subject to heat and pressure. This metamorphism can cause the minerals in the rocks to realign and form new bonds. As a result, gneiss can form from sedimentary or igneous rocks. 2. When two tectonic plates collide, the rocks along the plate boundary may be subjected to heat and ...
