Calcite veins

Today I have another beach scene but this time at North Berwick looking towards the Bass Rock with some distant oystercatchers waiting for the tide to ebb.
Here several veins of calcite cross the rock, indicating where water had seeped along fractures in the green volcanic ash rock which precipitated the formation of the pinkish-white calcite. A couple of kilometres further east we saw so many really interesting rock formations including some sedimentary rocks in among many different types of igneous rocks which resulted from the time when the area was subjected to much volcanic activity. It must be a geologist’s paradise and I really wished we had one with us.
