| Abstract/Notes | The Veliki Krivelj large porphyry-skarn Cu deposit in Serbia is located in the Timok metallogenic district on the western margin of the Tethyan metallogenic domain. The ore bodies are predominantly hosted in altered andesite, quartz diorite porphyry, skarn and marble, and are structurally controlled by NNW-trending faults. Previous studies have focused on porphyry Cu mineralization, while systematic understanding of skarn Cu mineralization remains limited. Based on detailed geological investigations of skarn orebodies, this study focuses on the geochronology and elemental geochemistry of garnet within them. Detailed petrographic investigations reveal that garnets occur in three lithological units: tuffaceous hornfels (Grt I), quartz diorite porphyry (Grt II), and marble (Grt III), exhibiting multistage compositional zoning: (1) Grt I displays core-to-rim evolution from Grt Ia (Gro69-75And25-30) ā Grt Ib (Gro44-63And34-55) ā Grt Ic (Gro0-14And86-99), marked by progressive depletion in grossular (Gro) and enrichment in andradite (And); (2) Grt II transitions from Al-rich cores (Grt IIa: Gro33-46And52-66) to Fe3+-dominant rims (Grt IIb: Gro1-9And90-98); (3) Grt III comprises pure andradite (Gro0-4And95-99). Trace element analyses indicate that Grt Ia and Grt Ib display weak HREE enrichment with LREE depletion, weak or absent Eu anomalies, and uniform Y/Ho ratios, suggesting formation in a reduced, low water/rock ratio, near-neutral closed system dominated by magmatic fluids. In contrast, Grt Ic, Grt IIa, Grt IIb, and Grt III exhibit LREE enrichment with HREE depletion, pronounced positive Eu anomalies, and variable Y/Ho ratios, indicative of formation in an oxidized, high water/rock ratio, weakly acidic open system involving both magmatic fluids and variable contributions from meteoric water. Garnet U-Pb dating constrains skarn Cu mineralization at 86.4 Ā± 1.9 Ma, coeval with porphyry mineralization (ā¼88 Ma) and quartz diorite porphyry emplacement (85ā87 Ma). Comprehensive analysis suggests that the porphyry and skarn mineralization belong to the products of the same magmatic-hydrothermal mineralization system, and the quartz diorite porphyry may be the parental rock of the Veliki Krivelj skarn. This study provides critical mineralogical constraints for guiding further exploration in the mining area. |
