Герберт тауларының геологиялық құрылымы мен тарихы

The Herbert Mountains are a conspicuous group of rock summits on the east side of Gordon Glacier in the Shackleton Range of Antarctica. They were first mapped in 1957 by the Commonwealth Trans Antarctic Expedition and named for Sir Edwin S. Herbert, Chairman of the Finance Committee and a Member of the Committee of Management of the expedition, 1955–58.

Rocks in the Herbert Mountains include gneisses of migmatite and pyroxene biotite, schists of garnet kyanite and minor occurrences of quartzite, Marble and calc silicates. There is post tectonic basalt in Mount Sheffield that may be connected with from the Jurassic Ferrar Dolerite. The age of rock samples from the Sumgin Buttress very from c. 268 million years for fuchsite, quartz schist to c. 434 million years for whole rock and amphibolite. These dates may be understated due to the loss of radiogenic Argon 40.

In association with the names of glacial geologists grouped in this area, named by the UK APC in 1971 after Thomas F. Jamieson (1829 1913), Scottish geologist whose work on the ice worn rocks of Scotland developed the true origin of glacial striae in 1862; originator of the theory of isostasy in 1865.

In association with the names of glacial geologists grouped in this area, named by the UK APC in 1971 after Percy Fry Kendall (1856–1936), English glacial geologist; sometime Professor of Geology, Leeds University.

. A peak rising to c. on the central ridge of Herbert Mountains, Shackleton Range. The feature is notable for a monolith forming the summit. Photographed from the air by the U. S. Navy, 1967, and surveyed by the BAS, 1968–71. In association with the names of glacial geologists grouped in this area, named by the UK APC in 1971 after Charles Maclaren (1782 1866), Scottish naturalist who in 1842 was the first to recognize the glacial control of sea level.
