The British Geological Survey (BGS) has kindly allowed us to link to their online geology map of Great Britain so you can see the locations where the rocks were collected. 

The BGS map illustrates the geology of the local area and includes a key to the rock types. The map can be navigated and zoomed, and the transparency of the geological overlay can be varied. In the example illustrated below the geology shows the sample to be the Shap granite pluton in a slightly lurid pink colour, but increasing the transparency to full reveals the satellite image of the quarry (if the base map is set to one of the satellite images available).
