Full textTourmalines, scheelites and magnetites from orogenic gold deposits (n=22) and glacial sediments (n=5) of the Val-d’Or mining district (Québec, Canada) were investigated by Electron Probe Micro-Analyzer (EPMA) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) in order to determine their chemical signature and to assess their potential as indicator minerals for gold exploration. Type I tourmalines from orogenic gold deposits hosted in felsic and intermediate calc-alkaline rocks have low contents of V, Cr, Mn, Fe, Co, Ni, Zn, and Sn and a high content of Mg compared to Type II tourmalines from orogenic gold deposits hosted in mafic tholeiitic rocks. Type III tourmalines from orogenic gold deposits located at the contact between mafic volcanic and metasedimentary rocks show a chemistry similar to Type I tourmalines with slightly higher Li, Mn, and Pb contents. Tourmalines from orogenic gold deposits are characterized by lower contents of Zn, Cu, Sn, and Pb than tourmalines associated to Cu-Zn, Pb-Zn-Cu, and Sn mineralizations. Till tourmalines carry the chemical signature of tourmalines from orogenic gold deposits with a majority carrying the signature of Type I tourmalines. Scheelites from orogenic gold deposits of the Val-d’Or district hosted in calc-alkaline intrusions of intermediate composition are characterized by high Na, REE, and Y contents compared to scheelites from sediment- or mafic-hosted gold deposits. Till scheelites carry the chemical signature of scheelites from orogenic gold deposits. Magnetites are rare in orogenic gold deposits of the Val-d’Or district. Magnetites of hydrothermal origin occuring in gold veins are characterized by higher contents of Cr, Zn, Mn, K, Ca, Ti, and Al than magnetites of magmatic origin found in the dioritic or gabbroic host rocks. Magnetites associated to the gold mineralization form fine disseminated grains (< 0.05 mm), which suggests that the coarse magnetites recovered in the till probably do not originate from the gold-bearing quartz veins.

Full textThis thesis proposes the implementation of a reliable methodology, based on the characterization of ores at the exploration stage. The main environmental issues for the mining industry are acid mine drainage and contaminated neutral drainage. Sulfides and sulfosalts, when in contact with water and oxygen, oxidize at different rates, resulting in the production of acid and release of various contaminants. Samples of pure sulfides were submitted to geochemical testing to determine their oxidation rates. The pure minerals can be ordered from the highest to the lowest reactivity as: gersdorffite > pyrrhotite > arsenopyrite > Ni-pyrite > Ni-pyrrhotite > Fe-sphalerite > pyrite > galena > chalcopyrite. Galvanic interactions between pyrite, chalcopyrite, and sphalerite were geochemically investigated. Pyrite was galvanically protected in presence of chalcopyrite, and partially protected in presence of sphalerite. Five synthetic tailings, simulating realistic tailings sulfides compositions, were prepared to compare geochemical behaviors and produce a better assessment of the acid-generation potential (AP). A new method is proposed by adding a kinetic factor. Ten polymetallic and gold sulfide ores were fully characterized with multidisciplinary techniques. Mineralogical investigations allowed for the mineralogical quantification of the ores, and for the knowledge of trace elements and their speciation. A method was developed to automatically quantify sulfides by multispectral optical microscopy. Detailed mineralogical work can save time and money and allows detecting the problems at the beginning of mining developments, improving mine waste management and mine closure planning

Full textFault zone structure is characterized by a fault core (gouge, cataclasite, mylonite), a damage zone (small faults, fractures, veins fold) and a protolith. We can clearly describe these structures in the Soultz-sous-Forêts granite (HDR Project, France) and in the Nojima Fault zone (Kobe, Japan). This work shows us that the structures are the same ones in the two sites in spite of their different deformation mode : one in extension and the other in compression. We propose, starting from the petrographic observations, a study of porosity and physical properties, a fluid flow model in a altered and fractured granite, taking into account the evolution of the fluid pressure and the processes of dissolution-precipitation during an earthquake. In the case of extension, the intersismic period is associated to an opening of the fractures in the fault damaged zone and an increase in porosity due to the rock alteration. During the earthquake, the fractures are closed and the fluid is expelled. In the case of compression, the intersismic period is associated to the closing of the fractures in the matrix and the expulsion of the fluids towards the fault whereas during the earthquake the fractures open because of the fluid pressure increase. Thus, there is a constant competition between the processes which enhance permeability and those which tend to reduce it. These processes (stresses, mineral precipitation, fluid pressure variation. . . Etc) are the same ones in the various contexts, but they do not interfere at the same time during an earthquake
