To evaluate and upscale the feasibility of using exploration tunnels in an operating mine for active-source seismic imaging, a experiment was conducted at Neves-Corvo mine, southern Portugal. Four profiles were deployed drifts approximately 650 m beneath ground surface, above world-class Lombador volcanogenic massive sulfide deposit. In addition to tunnel profiles, two perpendicular surface tunnels. The survey possible due newly developed prototype global positioning system (GPS) time...
Topographic mapping in Brazil has been performed without the direct application of cartographic theory to reflect local conditions. This problem is even more pronounced regarding large-scale mapping. Due this motivation, we describe method and related results that have developed propose a set symbols for topographic at large scales municipalities Paraná, Brazil. We study by considering principles aligning them with definitions Brazilian systematic The first step research was making decisions...
ABSTRACT Seismic methods are becoming an established choice for deep mineral exploration after being extensively tested and employed the past two decades. To investigate whether early European mineral‐exploration datasets had potential seismic imaging that was overlooked, we recovered a low‐fold legacy dataset from Neves–Corvo mine site in Iberian Pyrite Belt southern Portugal. This comprises six 4–6 km long profiles acquired 1996 targeting. Using today's industry‐scale processing...
Abstract The recently discovered massive and stockwork sulphide mineralization of Semblana-Rosa Magra Monte Branco, situated ESE the Neves–Corvo volcanogenic (VMS) deposit in Iberian Pyrite Belt (IPB) is presented. Geological setting tectonic model discussed based on proxies such as palynostratigraphy U–Pb zircon geochronology. found within IPB Volcano-Sedimentary Complex (VSC) Lower sequence, which includes felsic volcanic rocks (rhyolites) with ages zircons 359.6 ± 1.6 Ma, black shales...
ABSTRACT Neves–Corvo is one of the biggest mining districts on Portuguese side Iberian Pyrite Belt hosting six different lower Carboniferous copper, zinc, lead and tin orebodies including Lombador, Neves, Graça, Corvo, Zambujal, Semblana. During past 50 years, geological, geochemical, geophysical methods were utilized in exploration volcanogenic massive sulfide deposits at Neves–Corvo. Electromagnetic, earth resistivity, principally gravimetry played major roles area. However, 2011, as depth...
During the last decade, and possibly in years to come, mineral exploration geophysics has strongly pushed itself towards developing new instruments hardware solutions capable of addressing ever challenging near-mine brownfield issues. New data will be acquired but higher noise levels restricted access due mining activities infrastructure increase challenge acquiring sufficient quality answer key geologic questions define additional resources. Companies that value their existing reassess them...
Seismic methods are an affordable and effective way of studying the subsurface for mineral exploration. With goal testing new technologies exploration in highly challenging mining areas, early 2019, innovative seismic survey was conducted at Neves-Corvo mine, south Portugal. We have focused on data results from surface array data, whereas other work deals with underground data. The consisted two perpendicular 2D profiles positioned above known world-class tier-1 Lombador deposit....
Abstract This work investigates the relationships between partial melting, melt extraction, pluton growth and silicic volcanism in garnet-bearing felsic volcanic rocks that were extruded Iberian Pyrite Belt, at ca . 345 Ma. The garnets are of peritectic origin, displaying textural chemical features disequilibrium crystallization during melting reactions involving biotite high temperatures (up to 870 °C) middle-lower crust. Major element composition suggests compositional equilibrium with...
Several blind massive sulphide deposits associated with the Iberian Pyrite Belt (IPB) Volcano-Sedimentary Complex (VSC) (Figure 1) were discovered in SW Iberia using joint interpretation of geological and geophysical models, such as Neves-Corvo (Albouy et al., 1981; Leca 1983) Lagoa Salgada (Oliveira 1998) Portugal, Valverde Las Cruces Spain. In IPB Portuguese sector, former government agencies Serviço de Fomento Mineiro (SFM) Instituto Geológico e (IGM), well LNEG, fostered acquisition...

Summary The 150 Mt Lombador massive sulphide deposit is one of the seven known deposits Neves-Corvo mine, in southern Portugal. dips approximately 45º to NE and open down dip, with current exploitation reaching 1 km depth. To investigate possible continuation a 1D constrained inversion time-domain electromagnetic (TEM) ground loop data was conducted, followed by 3D EM forward modeling gravimetric over same area. perform gravity modelling/inversion, geologic model built using density database...
ABSTRACTTopographic maps are widely used to provide geospatial information on digital environments, and the principles of cartographic communication positively impact its design. This paper proposes new road building symbols in mapping Brazilian urban areas, aiming increase effectiveness map-reading tasks (MRTs) a multi-scale context. For this purpose, colour theory semiotics were applied develop remote test through an adapted think-aloud protocol. The results showed that users performed...
Summary Three- and four-dimensional geological models provide important means for mineral exploration as they help to unravel the tectonic depositional history of an area. They also serve outline alteration zone patterns, establish ore-bearing fluid migration paths identify potential areas deposition minerals in economic concentrations. Geological constraints within geophysical modelling process contribute generation new targets exploration. In this work, we present a 3D model Neves-Corvo...
