singularity based on fractal and multifractal is a technique for detection of depletion and enrichment for geochemical exploration, while the index of vertical geochemical zonality (vz) of pb.zn/cu.ag is a practical method for exploration of blind porphyry copper mineralization. in this study, these methods are combined for recognition, delineation, and enrichment of vz in jebal- barez in the s...

in this research work, the frequency domain (fd) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. in order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and blind mineralization using the surface geochemical data for the dalli cu-au porphyry deposit, a ...

Different methods have been developed for mineral exploration so far, amongst which biological-based methods known as geomicrobiological studies are of the most recent ones. Geomicrobiology as an interdisciplinary approach has achieved great progresses during the past two decades and involves the study of microbes in a number of fundamental geological processes, both in the past and present. Th...

In this work, the concentration gradient (CG) analysis of local-scale exploration for Porphyry-Cu deposits is applied in two zones using the G(Vz) index (CG(Zn*Pb)/CG(Cu*Mo)). The first zone is covered by a 1:2000 map of the Sungun and Astamal areas in NW Iran and the second one in the Inza area in British Columbia, Canada. The rock samples are taken from Sungun and Astamal and the soil samples...

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

BACKGROUND Because recent data on the effects of mineral concentrations in preterm infant formula on bone mineralization are lacking, recommendations for the mineral content of preterm infant formula differ greatly between committees. OBJECTIVE The goal of the study was to assess the effects of an isocaloric, nutrient-enriched preterm formula, which was fed from the age when full enteral feed...

objective: the present study aimed at investigating the relationship between attachment styles and self-efficacy in blind and non-blind female high school students in tehran. methods: the statistical population consisted of all female students studying in grades one or two in tehran girl’s high schools, in the academic year 2014. the study design was causal-comparative, conducted on 120 subject...

background: teachers, parents and foundations should become objective-oriented for children with visual impairment so that learning and sensitization of necessary knowledge and skills for the behaviors of these children are assisted. where there is impairment in the relations of children caregivers, their emotional security is disturbed and its effects will appear in their behaviors. therefore,...
