Cape Purvis
Cape Purvis () is a cape forming the south extremity of Dundee Island, off the north tip of Antarctic Peninsula. Its topography is that of a promontory which forms a mesa. The rest of the island is smooth. ==Composition==
The only large, accessible portion of Cape Purvis is at its southwest.〔http://journals.cambridge.org/action/displayFulltext?type=1&fid=466923&jid=ANS&volumeId=18&issueId=03&aid=466922〕 It is composed of recently-formed volcanic rock.〔http://journals.cambridge.org/action/displayFulltext?type=1&fid=466923&jid=ANS&volumeId=18&issueId=03&aid=466922〕 The basalts on Cape Purvis are have similar composition to lavas on Paulet Island, which is 5 kilometers east of it. Said composition is relatively low in magnesium oxide but high in titanium dioxide, calcium oxide, and niobium.〔http://journals.cambridge.org/action/displayFulltext?type=1&fid=466923&jid=ANS&volumeId=18&issueId=03&aid=466922〕 Cape Purvis's snow and ice-covered summit boasts an unnamed hill at its northern edge.
