Ultramafic rocks, Table Mountain, Newfoundland
Ultramafic rocks on the broad plateau at Table Mountain, Newfoundland. Part of an ophiolite sequence involving oceanic crust and mantle rocks. Metals in the rocks and lack of calcium limit plant growth. 1: U Maine group - Tom Weddle (MGS), Roger Hooke (UM), Steve Norton (UM), Joe Kelley (UM), George Jacobsen (UM), Julia Daly (UMF).

Ultramafic rocks, Table Mountain, Newfoundland
Ultramafic rocks exposed on Table Mountain are part of an ophiolite sequence including oceanic crust and mantle rocks. Images show examples of cumulate layering in the ultramafic rocks and some thin chromitite layers.

Conglomerate on Sally Mountain
Conglomerate (Silurian) on Sally Mountain. Pebbles and cobbles are mostly derived from the underlying Attean pluton (Ordovician), described as a quartz monzonite. Matrix is mostly quartz sand with some feldspar grains. Project Name: Marvinney Historical Photoshttps://digitalmaine.com/mgs_geologic_field_photos/36884/thumbnail.jp
