Stratigraphy and structure of Deception Island, South Shetland Islands, Antarctica

Deception Island is an active volcano with a large structural collapse that has been interpreted by several investigators as having been generated by different processes. The general stratigraphy and structural study of the volcano is presented, with special emphasis on the distribution and structur...
