Geology of the North Slope of the Puerto Rico Trench
Bathymetric and continuous seismic reflection profiles and rocks dredged in 1962 and 1964 are used to describe topography, stratigraphy and structure of the North Slope of the Puerto Rico Trench between 65 degrees 00 min W and 66 degrees 30 min W. Abundant basalt, chert, pink and green claystone and minor limestone and soft mudstone were dredged from 3200-3700 fms at 20 degrees 16 min N, 65 degrees 42 min W. The basalt has porphyritic, amygdular or diabasic texture, is partly altered to montmorillonitic clay, contains plagioclase which is mainly labradorite or bytownite, is low in potassium and titanium, and is normally tholeiitic.
