Determining the amount of trophy in aquatic ecosystems is important because increasing the availability of nutrients is affectings all levels of aquatic ecosystems as well as changes in species abundance, migration, reduce in biodiversity and changes in the structure and composition of communities. Therefore, there should be a proper method for determining the trophy state or production in t...
At the south of Bardsir, Kerman province, Iran, southeastern part Urmia-Dokhtar magmatic arc (UDMA), a large number gabbroic intrusions are intruded into Eocene lava flows and pyroclastic rocks with form small stocks dykes. In this paper, geochemical variations, evolutions, origin these investigated. The studied characterized by fine-grained margins resulting from rapid cooling flow differentia...
The application of machine learning (ML) algorithms for processing remote sensing data is momentous, particularly mapping hydrothermal alteration zones associated with porphyry copper deposits. unsupervised Dirichlet Process (DP) and the supervised Support Vector Machine (SVM) techniques can be executed main objective this investigation to practice an algorithm that accurately model best traini...
[1] Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations and new estimates of crustal shortening in Iran define the Cenozoic history of the Neotethyan ocean between Arabia and Eurasia. The new constraints indicate that Arabia-Eurasia convergence has been fairly constant at 2 to 3 cm/yr since 56 Ma with slowing of Africa-Eurasia motion to <1 cm/yr near 25 Ma, coe...
In this paper, correlation between rock types and Cu mineralization obtained by Concentration-Number (C-N) fractal model calculated in Kushk-e-Bahram Cu deposit, Central Iran. This deposit is located in the Urumieh-Dokhtar magmatic arc (UDMA). The main subject in this study was determination of relation between the Cu grade populations and rock types based on subsurface data using logratio matr...
