Pebble dikes are tabular bodies of breccia, which consist of angular to rounded clasts of quartzite, shale, carbonate, and minor igneous rock cemented in a fine-grained clastic matrix. All clasts now lie above or adjacent to corresponding source rocks. Dikes are thin, typically less than

En el centro del Perú, distrito de Santa Bárbara de Carhuacayán - Junín, se ubica el yacimiento minero Carhuacayán el cual es un sistema porfirítico cuya evolución produjo mineralización polimetálica cordillerana (Zn-Pb-Ag) como evento tardío de gran interés; asimismo, ésta actividad magmático-hidrotermal genero el emplazamiento temprano de varias fases intrusivas félsicas, llegando algunas de ellas a constituir manifestaciones de mineralización tipo pórfido de Cu±Au±Mo. La mineralización cordillerana la encontramos como rellenos de espacios abiertos, mantos de remplazamientos y brechas

Quatre parageneses successives decrivent la mise en place des mineralisations sulfurees de cambounes. Les 3 premieres sont dues a la remobilisation in situ d'une mineralisation stratiforme cambrienne lors de la deformation hercynienne majeure. La paragenese a antimoine, tardihercynienne est associee a des fluides hydrocarboniques et hypersalins. La paragenese a cu-pb est complexe et depend de la temperature de formation et de la proximite des mineralisations preexistantes

Abstract:
This project was initiated with the aim of determining the origin and evolution of the Belo Brdo Pb-Zn (Ag) carbonate-replacement and vein-type deposit in the Kopaonik metallogenic district of Serbia and Kosovo and to test its potential genetic association to nearby porphyry Cu-Au and skarn deposits. Hydrothermal-replacement, stockwork, skarn and vein-type base metal deposits in the region are related to a Tertiary (65.5 to 1.8 Ma) volcano-magmatic complex that intruded a tectonic nappe pile that includes a Triassic (251-199.6 Ma) Metamorphic Complex, a Jurassic (199.6 to 145.5 Ma) Ophiolite U

Abstract:
The 'Golden Quadrilateral' of W. Romania is a rich mineralised magmatic province hosting major porphyry-Cu and epithermal Au-Ag deposits. The mineralisation is associated with extensive magmatism emplaced along a series of NW-SE trending pull-part basins (e.g. Brad-Sacaramb, Rosia Montana). These basins developed during the Miocene, owing to the opposite sense rotation of the ALCAPA and Tisza-Dacia micro-continents, which facilitated extension-related melting of the subduction modified sub-continental lithospheric mantle. The largest of these basins, the Brad-Sacaramb basin contains extensive

The Falun pyritic Zn-Pb-Cu-(Au-Ag) sulphide deposit, situated in the Palaeoproterozoic (1.9–1.8 Ga) Bergslagen lithotectonic unit in the south-western part of the Fennoscandian Shield, is one of the major base and minor precious metal sulphide deposits in Sweden. Host rocks to the deposit as well as the ores and altered rocks were metamorphosed and affected by heterogeneous ductile strain during the Svecokarelian orogeny the total duration of which was 2.0–1.8 Ga. These processes both reworked the mineral assemblages of the original hydrothermal alteration system and reshaped the structural ge
