St Andrews and the East Sands Viewed from the Fife Coastal Path
One of two geological photos posted today which were taken on the Geoheritage Fife geology fieldtrip. Here St Andrews and the East Sands can be seen in the distance. In the fore ground the rock strata can be seen to curve round on each other. This is the eroded centre of a geological anticline, where the originally flat-lying rocks have been buckled into a fold by earth movements. If you hold a piece of paper in both hands and buckle it you can form an arch (anticline), or if the arch is upside down , a syncline. Anticlines consisting of porous rocks (sandstones) when covered by impervious rocks (shales) form the trapping mechanism of most of the world's major oilfields. Beyond the syncline there is another recurve of the rocks, which form an anticline and I think that you can see a break in the rocks caused by a geological fault.
