and gabbros is beyond determination, but certain it is that these latter 

 were forced through calcareous deposits rending them asunder and em- 

 bracing small areas of them in the plutonic rocks. At a distance from 

 the anorthosites the series exhibits but slight disturbance. On the west 

 the limestones rest on the gneisses in such a way that, as shown by C. H. 

 Smyth, Jr., they can be stratigraphically quite well worked out, but in 

 the east and in the central portion the intrusions have been so extensive 

 and the disturbance so enormous that the true succession is difficult to 

 decipher stratum by stratum.
