Title: MAIN FEATURES IN GEOLOGY AND METALLOGENY OF THE PANAGYURISHTE ORE REGION
Abstract: The Panagyurishte ore district is located in the Central Sredna Gora and partly in the Stara Planina mountains. It is an element of the Upper Cretaceous ApyseniBanat-Timok-Srednogorie Magmatic and Metallogenic Belt. Forming of this ore region is determined by the development of intensive Upper Cretaceous volcanic and magmatic activity. Magmatic rocks belong to two petrochemical series: calc-alkaline and subalkaline ones. Magma generation took place in enriched upper mantle with variegating participation of crustal component. It is established following well expressed volcano-intrusive complexes: Elatsite-Chelopech, Krassen-Petelovo, Vrankamik, Assarel-Medet, Svoboda-Ovchihulm, Elshitsa and Pesovetz. Magmatic activity is realised during Conniasian-Santonnian and the distinct migration from north to south is established. Ore fields include Elatsite-Chelopech, Krassen-Petelovo, Assarel-Medet, Radka and Elshitsa. Metallogenic specialisation of the region is determined by numerous Cu, Cu-Mo and Cu-Au porphyry deposits associating with high to intermediate sulphidation epi- to mesothermal massive sulphgide Cu-Au, Cu-Pyr-Au and Cu-Pyr deposits. Intermediate to low sulphidation Cu, Pb-Zn-(+ Au), Cu-Pb-Zn--(+ Au), Au и Ba deposits related to brittle faulting are developed in the marginal parts of the ore fields. Mn ore occurrences type “silicified umbra” are found in volcano-sediment rocks in the region.
