Abstract. Livingston Island is the second biggest island of the South Shetland archipelago. It is situated between South-Shettland channel from the North and the rift structure of the Bransfield Strait to the South. The following lithological structures are distinguished: metasedimentary complex of the Mayers Bluff formation; volcanogenicsedimentary complex of the Bowles formation; arc plutonic complex of the batholit of Antarctica peninsula; multiple dyke complex and Qaternary tholeitic and alkaline lavas of the Point formation. Detail geomagnetic investigations have been carried out during the period January-February 2005 in the region Hesperides cape at Livingston Island, Antarctica, as a continuation of the small-scale magnetic prospecting of the Hurt Peninsula in 1996-1997. The obtained results prove the high effectiveness of the magnetic method in the detail mapping of the outcropping Lower Cretaceous intrusive body of gabbro-diorite to quartz-diorite composition. The dyke formations, intruded within flish-lice rocks of Permian and Triassic age from the Mayers Bluff formations, have been successfully traced. Geology–geographics characteristics of the region The region of Antarctica, including the continent Antarctica and the surrounding ocean, is not enough investigated region of the Earth.
