In reflex epilepsies, alteration of γ oscillations may mediate transition between interictal and ictal states. Here, we explored a patient having seizures triggered by syrup intake. From intracranial electroencephalography combined with functional MRI, the overlap of the gustatory cortex and of the preictal and ictal onset zones, as defined by early gamma changes, motivated the successful resec...

This paper documents the exploration significance of Ag/Au, Au/Cu, Cu/Mo and (Ag×Au)/Cu×Mo) ratios of the supra-ore and sub-ore halos versus fluid inclusion evolution for 24 Cu, 6 Cu- Mo and 10 Cu-Au porphyry deposits worldwide. The ratios are based only on the economic and mineralized hypogene alteration zones. The results indicate that (Ag×Au)/(Cu×Mo), Au/Cu and Cu/Mo ratios increase with dec...

Dynamic zoning (systematic alteration in the spatial and temporal allocation of even-aged forest management practices) has been proposed as a means to change the spatial pattern of timber harvest across a landscape to maximize forest interior habitat while holding timber harvest levels constant. Simulation studies have established that dynamic zoning strategies produce larger tracts of interior...

Brownfield areas are important targets of exploration; however, the extensive drilling present in these has not fully exploited their prospective potential. The appropriate use drill hole cores can play an role deep exploration. We a case study iron oxide-copper-gold (IOCG) Furnas Southeast deposit, located Carajás Mineral Province, Brazil. This deposit disseminated chalcopyrite, bornite and go...

Bentonite deposits of economic interest are widespread in Tashtab Mountains (Khur), east of Isfahan province, Iran. Several bentonite deposits have been developed in this area as a result of Eocene volcanic alteration. These deposits are classified as Khur bentonite horizon. XRD analyses reveal that alteration products consist of Na-montmorillonite, kaolinite, quartz, calcite, and crystobalite....

Porosity and permeability alteration due to the thermo-poro-elastic stress field disturbance from cold fluid injection is a deciding factor for longer, more economic, safer heat extraction an enhanced geothermal system (EGS). In Soultz-sous-Forêts system, faulted zones are main flow paths, resulting porosity–permeability development over time reorientation sensitive in comparison with regions w...
