This paper presents a quantitative modeling for delineating alteration zones in the hypogene zone of the Miduk porphyry copper deposit (SE Iran) based on the core drilling data. The main goal of this work was to apply the Ordinary Kriging (OK), Artificial Neural Networks (ANNs), and Concentration-Volume (C-V) fractal modelings on Cu grades to separate different alteration zones. Anisotropy was ...

New emerging approaches in tissue engineering include incorporation of metal ions involved in various metabolic processes, such as Cu, Zn, Si into bioceramic scaffolds for enhanced cell growth and differentiation of specific cell types. The aim of the present work was to investigate the attachment, morphology, growth and mineralized tissue formation potential of Dental Pulp Stem Cells (DPSCs) s...

The behavior, bioavailability and toxicity of heavy metals in soil essentially relies on their chemical spices. This paper attempts to quantify the spices bound various fractions at five sampling stations (S1–S5) from Doustbaglu area, NW Iran, ascertain bioavailability, using sequential extraction. results revealed that more than 90% Cr Cu were retained residual fraction, signifying geogenic or...

The purpose of this study is to identify the enriched zones of Cu, Mo and Re in Nowchun Mo-Cu porphyry deposit (SE Iran) based on subsurface data and using of concentration–volume (C–V) fractal model. The C-V model illustrates four and five geochemical zones based on Mo and Cu distributions respectively and there are three geochemical populations for Re. The main mineralization for Mo, Cu and R...

Hydrothermally formed rutile is a common mineral in porphyry Cu (-Au-Mo) deposits and has the potential to provide versatile information about physical-chemical conditions timing of mineralization. In this study, we investigated trace element composition U-Pb dates hydrothermal by LA-ICP-MS together with its petrographic context, four well-studied systems: Batu Hijau (Indonesia), Bingham Canyon...

the area is located 20 km northwest of kashmar and about 4 km of kalateh taimour in khorasan razavi province. the study area is part of tertiary volcanic-plutonic belt north of daruneh fault and its situation in tectonic inliers between two important active faults, doruneh and taknar. volcanic rocks are mainly intermediate to acid pyroclastic type. they formed during early tertiary. the volcani...

In this paper, we aim to present a quantitative modeling for delineating the alteration zones and lithological units in the hypogene zone of Masjed-Daghi Cu-Au porphyry deposit (NW Iran) based on the drill core data. The main goal of this work is to apply Ordinary Kriging (OK) and concentration-volume (C-V) fractal model based on Cu grades in order to separate the different alteration zones and...

The Uanium mineralization within the Vempalli dolomites of Cuddapah Super group in Mabbuchintalapalli, , Tummalapalli area falling in the Survey of India Toposheet No. 57 J/7. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is taken as reference for the Interpretation studies. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is take...

The Zarshuran Carlin-like gold deposit is located at the Takab Metallogenic belt in the northern part of the Sanandaj-Sirjan zone, NW Iran. The high-grade ore bodies are mainly hosted by black shale and cream to gray massive limestone along the NNE-trending extensional fault/fracture zones. The aim of this investigation was to determine and separate the gold mineralized stages based on the surf...
