Argo Point (scoria cone)

Argo Point is a scoria cone in Jason Peninsula, Antarctica, at a height of 360 metres (1,180 ft) above sea level. Associated with the Seal Nunataks, the cone has a diameter of 300 metres (980 ft) and its snow-filled crater has a gap on its northern side. The cone is constructed on a formation of lava and scoria over 175 metres (574 ft) thick, which may lie on Jurassic rocks.

Potassium-argon dating has indicated ages of 1.4-0.9 mya. The cone is constructed from basalt and hawaiite including lava bombs in its sides. Similar to Seal Nunataks and James Ross Island the rocks of Argo Point are ocean island basalts. This volcanism may be the consequence of back-arc effects of subduction along the South Shetland trench.
