Age, Sr and Nd-Isotope Systematics, and Origin of Two Fluorite Lodes, Sierras Pampeanas, Argentina
Fluorite mineralization at the La Nueva and Bubu mines yields Sm-Nd ages of 131 ± 22 and 117 ± 26 Ma, respectively. Thus, the mineralization most probably is related to a late Gondwanian (Lower Cretaceous) extensional and magmatic event that affected the Sierras Pampeanas basement during the opening...
