Crispin, if you refer to the activities in the 80s to combat the  
effects of 'the Waldsterben' due to acid rain, that rock was limestone  
to mitigate the acidity... and it did help on a short-term basis. the  
long-term mitigation though came when they cleaned up the sulfuric  
emissions from the high chimneys that caused the acid rain in the  
first place.
