The massive sulphide deposits hosted in the Moroccan Hercynian massifs of Jebilets and Guemassa are Volcanogenic Massive Sulfide (SMV), deformed and metamorphosed. However, an assessment of the contribution of this deformation to their current structure and the eventual impact on the economy and in terms of exploration is missing. Therefore, this contribution aims mainly to define the structural context of these mineralizations, in order to deduce a structural model relating to Hajjar's VMS.The VMS of Hajjar, belonging to the domain of Guemassa (Western Meseta). It is hosted in volcanosedimentary terrain composed of pelites, sandstones and lentils and limestone bars intruded by felic and basic sills and dykes. The main volcanic bodies correspond to the rhyolitic plugs.The Hajjar deposit is composed of 3 mineralized bodies: main body (CP); north-eastern body (CNE); western body (CWD) and extreme western body(CEWD.). The Hajjar deposit is affected by a single XY plane of subvertical flattening of directions N0 to N45. The host rock and sulphide bodies have the same silicate metamorphic assemblages, which exhibit either a "static" granoblastic texture when the strain is low or pre to syn-tectonic features when the foliation is strongly expressed. The texture shapes, and aggregates of the biotite and andalousite (± suspected cordierite) are typical of HT/LP “contact” metamorphism in the hornfels facies. The syn-tectonic assemblage is composed of quartz + chlorite + white micas (± calcite) and partially replaced the former biotite and andalousite blasts. The data from the N’Fis block show the occurrence of a single sub-vertical XY plane oriented N130. The biotites of contact metamorphism are elongated parallel to the foliation. These data imply that the Hajjar MSD and the N’Fis block are affected by a single foliation which encompasses a HT/LP contact metamorphism. The significant inflexion of foliation from Imarine outcrops to Hajjar VMS is due to major right-lateral ENE-trending transpressive shear zone at Hajjar. Near the Hajjar mine, such a regional shear zone is recognized for the first time, and is a structural key feature of the Hajjar district.The mineralization of Hajjar is strongly deformed and metamorphosed. It is affected by folding, foliation and mylonitic bands within a regional scale shear zone. Structures such as pyrrhotite-rich ribbons clearly pre-date the deformation and the HT/LP contact metamorphism. The early stage is characterized by the precipitation of pyrrhotite, pyrite, arsenopyrite, sphalerite, and galena, whereas the synkinematic stage constitutes major concentrator event characterized by the dissolution and recrystallization of early paragenesis with enrichment in Zn, Cu. The late post-kinematic stage is responsible for the neoformation of sulphides, namely chalcopyrite, pyrite and some traces of sphalerite.We have demonstrated a tectonic thickening within the fold hinge zone. pre-syntectonic metamorphism favors ductile behavior and sulfide recrystallization (Po, Cpy, and Sph). The polymetallic veins argue for hydrothermal fluid-assisted remobilization during deformation. All of our studies lead to the proposal of a 3D tectono-metamorphic model for the VMS of Guemassa and proposals to search extensions of the mineralization

Mineral exploration focused on deeply concealed targets at depth requires effective techniques applicable in the field in order to identify ore-forming systems on a large scale and pathfinders to locate ore on a smaller scale. According to the rapid development of portable equipment in recent years, the importance of near real-time analysis in the field has been increasing by helping fast decision-making support before laboratory requests.Spectroscopic analysis using individual equipment has been widely used in the exploration of mineral resources, but it is rare to apply integrated data from several techniques to characterize “vectors”, which provide variations in lithology, geochemistry, mineralogy, and mineral chemistry. In addition, it is even rarer if the combination of spectral data is obtained from various portable instruments. Therefore, this study aims at reconciling geochemical data acquired from portable spectroscopic devices in order to determine the best geochemical information from each technique applied by combining the mineralogical and elemental information. Elemental and mineralogical data are provided in this study by six portable techniques: (i) elemental analyses such as XRF and LIBS for major, trace, and light elements, and (ii) mineralogical analyses such as Raman, VNIR-SWIR, MIR, and XRD to constrain rock-forming, ore, and alteration minerals.The final objective of this study is to identify vectors to the ore by applying the reconciled multi-spectral data obtained from the “real” sample in the Elvira volcanogenic massive sulfide (VMS) deposit. To achieve this, step-by-step procedures were carried out: (i) methodological understanding of each technique, (ii) establishment of a spectral database consisting of naturally monomineralic minerals, (iii) design of a decision tree to classify by mineral or mineral classes based on diagnostic bands, and mineral identification and quantification of (iv) carbonate and (v) phyllosilicate minerals (i.e., trioctahedral chlorites and dioctahedral micas), which are indicators of the target deposit.Several limitations of portable spectroscopy were confirmed based on the device itself and the geological environment in the Elvira deposit. Nevertheless, portable spectroscopy is effective in identifying the presence and compositional changes of various minerals from heterogeneous rock samples. Therefore, spectroscopic analysis on-site can be one of the vectoring tools to determine the implication for ore mineralization in hidden ore explorations
