|Name||Cambrian thru Middle Ordovician carbonate rock|
|Geologic age||Cambrian - Middle Ordovician|
Sedimentary > Carbonate (Melange)carbonate rock - occuring as slivers caught along thrusts of later allochthones, or carbonate blocks in Taconic Melange.
|Comments||part of Lorraine, Trenton, and Black River Groups up to 4500 ft. (1400 m). Note that this unit is also in the Beekmantown and Stockbridge Groups, Potsdam Sandstone, and Vermont Valley Sequence. It has no name mentioned on the printed map, only refers to "slivers, as OCAls above". The same color and symbol are used so I have combined both units into this one (didn't make sense to create a new province for just this one unit; especially since the same color and symbol are used). Also note that on printed map there is a unit OCAh which refers to "Horses along normal faults". It is the same color as this unit (OCAs) and is not used in the digital map, so I have included it within this description.|
