南极半岛中-新生代金属矿产分布及成矿作用

Key Points

• Mineralization is primarily concentrated in the Early Cretaceous and Paleocene-Eocene epochs, indicating age significance.
• Key geochemical characteristics like copper content and Sr-Nd isotopes reflect a magmatic origin under a subduction zone.
• Alteration features such as potassium and sericite indicate porphyry copper mineralization traits in low magnetic anomaly zones.
• The findings outline several regions with high potential for porphyry copper mineralization, aiding future exploration efforts.
