Making Scotland’s Geology Accessible to All
Through regular blogs, fieldtrips/geotours & education
With a sprinkling of structural geology, rock fractures and cultural curiosities, venturing outside of Scotland occasionally.
Low Angle Normal Faults
Low angle faults are mechanically unfavourable as normal faults usually initiate at around 60 degrees. Here we take a look at some ways in which we can explain the formation of low angle faults.
Mechanical Stratigraphy
This example of mechanical stratigraphy where thinner limestone beds are more fractured than thicker ones, is from Iran. Plenty of examples from Scottish geology here as well..
Fracture Swarms Explained
Here we look at zones of a high density of fractures called fracture swarms, their significance and some examples from outcrops in the UK.
Shear Fractures on Folds, St Andrews, Scotland
Steep beds of sandstone contain fractures here at St Andrews (Fife, Scotland) - these have formed during folding.
