A Note on the Petrographical Characters of some Rocks from the Northern Range of Trinidad
Published online by Cambridge University Press: 01 May 2009
Extract
In 1907 Mr. E. H. Cunningham Craig's Report on the ‘Metamorphic Rocks of Trinidad’ was published, containing a general description of the structure of and the beds composing the Northern Range of the Island, and this note is accordingly intended merely to call attention to the petrographical characters of some of these altered sediments included in the Caribbian Series of Wall and Sawkins, and by far the oldest rocks in the island.
