The NE-trending multiphase Late Devonian Eagle Lake granite (ELG) in southwestern New Brunswick is mineralized, consisting of hypabyssal porphyritic stocks and dikes that intruded Silurian metabasic volcanic rocks; however, its various phases, ages, associations with notable stockwork Cu–Mo–Au mineralization alteration have yet to been studied. ELG suite predominantly composed phenocrysts a mic...

In order to apply manure or compost to fulfill the nutrient requirements of a crop, knowledge of the amount of nutrients mineralized following application is needed. Nutrient mineralization from applied manure depends on temperature, soil moisture, soil properties, manure characteristics, and microbial activity. Since these factors cannot be accurately predicted, nutrient mineralization from ap...

The alka line and calc-alkaline volcanic activities in Mianch have reactivated the hydrothermal so lutions, resulting in the fonnation of epithermal mineralization in the region. The mineralized zone trending NWSE, and has been affected by NE-SW bended and folded structures. The precious and base metals mineralization are confined to structurally hended zone. Landsat-7(ETMJ data were used ...

The Mazra'eh Shadi is located about 130 km northeast of Tabriz (NW Iran) in the Arasbaran metallogenic belt. The deposit occurs as a series of veins within the Eocene andesites. Mineralization shows epithermal system that controlled by fault distribution. Epithermal textures within the veins include comb, vaggy quartz, cockade, boxworke, plate calcite and breccia. Pyrite is the main ore mineral...

The mineralization potential of arc magmas depends, among other factors, on the timing sulfide melt saturation relative to magma differentiation and exsolution a magmatic fluid phase. In fossil mineralized or barren systems, understanding evolution metals along path is often hindered by late processes hydrothermal alteration. To better understand process metal “caught in act” crustal reservoirs...

Age is one of the main factors involved in the development of neurological illnesses, in particular, Alzheimer, and it is widely held that the rapid aging of the world population is accompanied by a rise in the prevalence and incidence of Alzheimer disease. However, evidence from recent decades indicates that Cu and Cho overload are emerging causative factors in neurodegeneration, a hypothesis ...

The Zone 5 Cu-Ag deposit is the most consistently (for ~4.2 km) mineralized in Khoemacau district northwestern Botswana, with an underground mineable resource of ~100 Mt grading 2 % Cu and 21 g/t Ag. consists a redox-buffered metal-zoned ore body hosted preferentially by chemically reduced meta-sediments overlying oxidized hematite-bearing arkosic sandstone. Ore-grade mineralization typically v...

The hydrogeological system of an ecologically sensitive alpine floodplain in the Valle di Blenio, Switzerland, was investigated using hydrochemical and 3H-3He dating methods. Water samples from six wells and from different surface locations were analyzed. The analysis of the concentrations of major ions in conjunction with age determination by the 3H-3He-method allowed the main hydrological pro...

The northwestern part of the Kerman Cenozoic magmatic arc (KCMA) contains many areas with porphyry copper mineralization. In this research, we used the advanced space-borne thermal emission and reflection radiometer (ASTER) and Enhanced Thematic Mapper plus (ETM+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. The spectral meas...
