Coulman Island

Coulman Island in Fig. 16.35 is the most southerly volcanic center of the Hallet volcanic province and is located in the Ross Sea opposite the ice tongue of the [Pg.552]

Borchgrevink Glacier. The island is 35 km long and 15 km wide at its southern end which contains the Coulman caldera at 1,998 m. The caldera is about 5 km wide and at least 700 m deep. The lava flows that crop out north of the caldera are primarily basanite, basalt, and hawaiite. The rocks east of the caldera consist of a typical vent assemblage of hydrothermally altered alkali-rich lava flows (basanite to phonohte) and layers of tuff, all of which were intruded by dikes (McIntosh and Kyle 1990e). [Pg.552]

The chemical compositions of three rock samples from Coulman Island are identified in Fig. 16.36 as [Pg.552]


The volcanoes along the Ross-Sea coast of northern Victoria Land collectively form the Hallett volcanic province in Fig. 16.35. This province includes the Adare, Hallett, and Daniell peninsulas, and Coulman Island. Volcanic rocks of Cenozoic age also occur on the Possession Islands and at a few vents on the mainland west of the major volcanic complexes named above (McIntosh and Kyle 1990a). [Pg.550]

Adare Peninsula, HaUett Peninsula, Daniell Peninsula, Coulman Island, and the Possession Islands. The Cenozoic volcanic rocks in these areas are located adjacent to and may have been deposited on top of the low-grade metasedimentary rocks of the Robertson Bay Group of early Paleozoic age (Section 4.5) (Adapted from Gair et al. (1969))... [Pg.550]

Fig. 16.36 The volcanic rocks in the Hallett volcanic province range from basanites to phonolites and trachytes. The principal volcanic centers represented on this diagram are Cape Adare, Cape Hallett, Cape Daniell, Coulman Island, and the Possession Islands. The rock types are identified by the letters in each field Bn = basanite, Tp = tephrite, Ptp = phonotephrite, Tpp =...

Fig. 16.41 The Sr/ Sr ratios of the Cenozoic volcanic rocks on the islands off the coast of Victoria Land are lower than those on the mainland. The islands included here are Franklin, Coulman, Possession, Scott, and Balleny. The volcanoes on the mainland are Melbourne, Vulcan HiUs, Overlord, and The Pleiades, as well as the DanieU, HaUett, and Adare peninsulas (Data from Jones and Walker (1972) and Hart and Kyle (1993))...
