HISTORY OF ICE AGES
U.S. Geologists In Antarctica
The history of an earlier glaciation of Antarctica, and of the present ice-age there, is to be studied by a geological party from the Institute of Polar Studies, Columbus, Ohio. The party, which will work in the Queen Maud Mountains of the Ross Dependency, was in Christchurch recently.
The party leader, Mr W. E. Long, will investigate the Carbo-Permian glaciation of about 180 million years ago. Dr. R. P. Goldthwait, who is director of the institute, will collect evidence on the history of the present ice-sheets, estimated to be one million to two million years old. He will try to find out more accurately when they were formed, how high they reached in former times, and the dates of various changes in them. Mr D. McClelland will work on the basement (crystalline) rocks of the pre-Cambrian era of 1000 mil. lion and more years ago.
