In the area of the Iberian Massif corresponding to the CVP, the southern part of the CIZ including the CU, the structure of the crust has been investigated by means of two deep seismic reflection profiles: the ALACUDIA normal-incidence profile (ALCUDIA-NI in Fig.
6A) roughly marking the boundary between the outcrops of the CIZ with higher density values relative to the lower density values where the outcrops of the sedimentary rocks (e.
When considering the CIZ as outlined in Table 1, the total distance between channels 19 and 1 is approximately 35m.
The Pakeagama Lake pegmatite does not currently have a resource, however the mineralogy of the CIZ and the presence of lepidolite is similar to the CIZ found in the Tanco pegmatite and was the main tantalum zone at the Tanco mine.
In 2013-2014 junior company Mineral Exploration Network Ltd has carried out an extensive first-stage prospecting field work in the south CIZ area around Logrosan granitic pluton with a main view to discover Au and cocurrent W deposits.
The Neoproterozoic Schist Greywacke Complex (SGC) is the largest domain of the CIZ which is characterized by a thick (up to 11 km) metasedimentary turbiditic sequence, consisting mostly of pelitic and psammitic beds (Villaseca et al.
The Logrosan granite is one of the post-kinematic bodies of the Central Extremadura Batholith (Castro, 1985) that intrudes into epizonal domains of the CIZ.
The main Variscan deformation phases defined in the CIZ are also recognized in the area.
15), as well as plutonic terranes of the CIZ, indicated by feldspar content and presence of Rg fragments.
This evidence probably indicates a change in the type of eroded plutonic rocks of the CIZ from Petrofacies 1 to Petrofacies 2.
The OMZ is located between the Iberian Pyrite Belt (IPB--belongs to the South Portuguese zone) and the CIZ (Tornos and Casquet, 2005; Tornos et al.
They are predominantly from the vein-type deposits of CIZ and OMZ.
