On the other hand in training phase of any Artificial Intelligence (AI) based model, each training data set is usually a limited sample of possible patterns of the process and hence, might not show the behavior of whole population. Accordingly in the present article first, wavelet-based denoising method was used in order to smooth hydrological time series and then small normally distributed noises with the mean of zero and various standard deviations were generated and added to the smoothed time series to form different denoised-jittered training data sets, for Artificial Neural Network (ANN) modeling of monthly rainfall – runoff process of the Pole Saheb(Anyan) station in Zarrineh River watershed, which is a portion of orumiyeh lake drainage basin, that is located in Iran. To evaluate the modeling performance, the obtained results were compared with those of multi linear regression and Auto Regressive Integrated Moving Average models. Comparison of the obtained results via the trained ANN using denoised- jittered data showed that the proposed data pre-processing approach could improve performance of the ANN based rainfall-runoff modeling of the case study up to 38% in the verification phase.}, keywords = {Rainfall-Runoff modeling,ANN,Wavelet denoising,Jittered data,Zarrineh river watershed}, title_fa = {روانآب}, abstract_fa = {}, keywords_fa = {}, url = {https://jtethys.journals.pnu.ac.ir/article_3409.html}, eprint = {https://jtethys.journals.pnu.ac.ir/article_3409_e1e0be8b93e821660ca8369e4989769f.pdf} } @article { author = {}, title = {Geochemical and Petrogenesis of Granitoides rocks in South-East of Centeral Iranian Volcanic Belt, North-West of Share-Babak, Kerman Province, Iran}, journal = {Quarterly Journal of Tethys}, volume = {4}, number = {4}, pages = {295-311}, year = {2016}, publisher = {Payame Noor University}, issn = {2476-7190}, eissn = {2345-2471}, doi = {}, abstract = {In the Centeral Iranian Volcanic Belt (CIVB), north-west of Shahre-Babak, in area of Javazm, Dehaj and khabr, about 20 plutonic porphyritic tonalitic to granodioritic masses (1-50 km2) are intruded into a varity of rock sequences from Eocene to Early Miocene in age. Tonalitic and granodioritic rocks are some part of Dehaj-Sardoieh belt and having early Miocene age. The CIVB contains intrusive and extrusive rockes of Cretaceous-Quaternary age. Geochemical studied indicate that the subalkalic tonalitic to granodioritic masses belong to I-type granitoides and have an adakitic composition tendency with Na2O/K2O (1.82-2.57), high Sr (584-1040 ppm), Mg#=(0.2-0.52) and low Y (7.3-10.7ppm), low Yb (0.7-1.18ppm), and low HREE. Fractionated REE patterns show that, (Ce/Yb)N = 10-22, absence of negative Eu anomaly, low content of Y, Nb, Ti, and high Sr/Y (74-134) and (Ce/Yb)N ratios. Based on geochemical data the source of tonalitic and granodioritic magma was probably garnet-amphibolite or amphibole-eclogite, possibly generated during subduction of the Neo-Tethyan oceanic slab beneath the Central Iran microplate. The adakitic plutonism was followed by adakitic volcanism in Mio-Peliocene and eruption of alkaline magmatism in this area.

The results show relatively three areas of P-T condition for emplacement of NW MBPC granitoids: (1) Low- P and T (P< 5kb and T < 680°C) for Garnet-bearing monzogranite (Grt- MG) and quartz sample diorite, (2) High- P and T (~ 8 kb and T = 721°C) for garnet-bearing alkali granite (Grt- Alk Gr), and (3) Low- P and high T (P< 5kb and T > 750°C) for hornblende-bearing I-type granite (Hbl-granite) and hornblende-free S-type granite. The P–T estimation suggests that the hydrous felsic magma with S-type affinity were formed either by melting of deep crustal components followed by extensive assimilation of muscovite-bearing sediments or direct melting of muscovite-bearing metapelitic rocks at low pressure, both emplaced within muscovite-free domain of granitic system. The hydrous I-type felsic magmas which were mainly formed by melting of lower crustal materials cut the granite solidus at low pressure and show little evidence for assimilation of crustal components at emplacement level. The calibrations applied for NW MBPC granitoids indicates an important role for muscovite as H2O-supplier for felsic parent magma.
