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...
The Astaneh granitoid massif is located about 40 km to Arak city, central Iran, is a part of Sanandaj-Sirjan structural Zone. These intrusive rocks which are mainly composed of grnodioritic rocks, widely affected under hydrothermal alteration. The alteration zones, on the basis of field studies and mineralogy as well as the study of the REE behavior, are investigated in this paper. Eight altera...
Main aim of this study is to determine relationship between lead and silver mineralized zones using the Concentration-Volume (C-V) fractal modeling and logratio matrix based on subsurface data in Mehdiabad Zn-Pb-Ag deposit, central Iran. First, Pb and Ag raw data were analyzed by statistical processes and their histogram have similar shape. Next, Geostatistical modeling was carried out for the ...
Despite intense investigation, human replication origins and termini remain elusive. Existing data have shown strong discrepancies. Here we sequenced highly purified Okazaki fragments from two cell types and, for the first time, quantitated replication fork directionality and delineated initiation and termination zones genome-wide. Replication initiates stochastically, primarily within non-tran...
The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...
Marine organisms in intertidal zones are subjected to periodical fluctuations and wave activities. To understand how microbes in intertidal biofilms adapt to the stresses, the microbial metagenomes of biofilms from intertidal and subtidal zones were compared. The genes responsible for resistance to metal ion and oxidative stresses were enriched in both 6-day and 12-day intertidal biofilms, incl...
نظر به اهمیت کنودونتها در تقسیمات چینهنگاری پالئوزوئیک و گسترش قابل توجه نهشتههای دونین پسین و کربونیفر پیشین در منطقه کرمان سه برش چینهشناسی (حور، هوتک و شمس آباد) در شمال استان کرمان انتخاب و بویژه بر اساس کنودونتها و بقایای ماهیان مورد مطالعه قرار گرفتند. مجموعه کنودونتهای بدست آمده از برش حور شامل 20 گونه متعلق به دو جنس polygnathus و icriodus بوده و سنی معادل فرازنین پسین را نشان می...
Although feature co-localizations could serve as useful guide-posts to genome architecture, a comprehensive and quantitative feature co-localization map of the human genome has been lacking. Herein we show that, in contrast to the conventional bipartite division of genomic sequences into genic and inter-genic regions, pairwise co-localizations of forty-two genomic features in the twenty-two aut...
به منظور مطالعه بیواستراتیگرافی و پالئواکولوژی رسوبات دونین پسین، برشی در استان کرمان انتخاب گردید، که از لحاظ موقعیت زمین شناسی در ناحیه ایران مرکزی قرار دارد. برش باغین در شمال شرق باغین و 20 کیلومتری غرب کرمان واقع شده است. قدیمی ترین واحد دونین در این منطقه، سازند پادهاست که شامل ماسه سنگ های سفید و قرمز می باشد، این سازند به وسیله واحد هایی از دونین که معادل سازند بهرام می باشد، پوشیده می...
