Scotland: Faultlines and Thrusts...and Some Ruins
Scotland, as seen here, divides into 4 parts. Three fault lines and the Moine Thrust.
A seismologist’s dream (or perhaps nightmare).
The fault lines are basically like this
Known as simple faults they are areas where the plates rest but are not joined. When the plates slide over each other...it is called an Earthquake.
Scotland has had 28 low scale Earthquakes in the past 50 days.
The Moine Thrust is a completely different occurrence
As illustrated (by cake)
And the (not nearly as tasty) results in Scotland
Many different layers are thrust upward with the movement. The Moine Thrust Belt is a favourite with geologists who can see the exposed layers they otherwise might not have a chance to examine so closely, or easily.

Most of the rock in the area is gneiss, limestone, basalt or granite.
The best known formations are the basalt formations...both columnar and pinnacle.
Columnar Cliff Formations
Basalt Pinnacles
Perhaps one of the best known Basalt formations is here at Fingal's Cave
Another sight, although man-made not created by nature, is the vast array of ruins in the form of Abbeys that dot the Scottish Countryside.
A Photographer's Dream!
