Summary: | Geologic reconnaissance indicates that the Ellsworth Mountains consist mainly of thousands of feet of folded, slightly metamorphosed, clastic sedimentary rocks of unknown age. Three major stratigraphic units are recognized, but only fragmentary fossils have been found. The folding is asymmetric, overturned, or recumbent; fold axes strike north, 10° to 20° west. Basic igneous sills occur in the northern Heritage Range. |
