A revised pre-Jurassic chronology is presented for the Antarctic Peninsula on the basis of new U-Pb zircon dating, using both conventional (11 samples) and SHRIMP microprobe data (10 samples). The age range for plutonism and high-grade metamorphism is from 435 ±8 Ma (Silurian) to c. 206 Ma (approxim...
