abstract = "This paper presents the results of a study of bedrock samples obtained by drilling through 541 m of ice in north-western Princess Elizabeth Land. The drilling was aimed to decipher the geological nature of a high-amplitude linear magnetic anomaly running parallel to the coast for over 500 km from Princess Elizabeth Land to Mac. Robertson Land. The rock obtained by drilling is a melanocratic orthopyroxene-hornblende-biotite crystalline schist (mafic granulite) with a protolith age of ∼970 Ma. Two metamorphic events are identified: early metamorphism with an age of ∼890 Ma and peak parameters of 740–780 °C and 4.0–4.5 kbar; and late metamorphism with an age of ∼800 Ma and parameters of about 650 °C and ∼3 kbar. According to the data obtained, the linear magnetic anomaly can be interpreted as an island arc that was accreted to Antarctica during the assembly of Rayner Province.",

N2 - This paper presents the results of a study of bedrock samples obtained by drilling through 541 m of ice in north-western Princess Elizabeth Land. The drilling was aimed to decipher the geological nature of a high-amplitude linear magnetic anomaly running parallel to the coast for over 500 km from Princess Elizabeth Land to Mac. Robertson Land. The rock obtained by drilling is a melanocratic orthopyroxene-hornblende-biotite crystalline schist (mafic granulite) with a protolith age of ∼970 Ma. Two metamorphic events are identified: early metamorphism with an age of ∼890 Ma and peak parameters of 740–780 °C and 4.0–4.5 kbar; and late metamorphism with an age of ∼800 Ma and parameters of about 650 °C and ∼3 kbar. According to the data obtained, the linear magnetic anomaly can be interpreted as an island arc that was accreted to Antarctica during the assembly of Rayner Province.
