BACKGROUND: MULTIVARIATE ANALYSIS AS A CHEMOMETRIC TOOL HELPS GEOMETRICS FOR SOIL ANALYSIS IN PRODUCING INFORMATIVE RESULT. USING OF MODERN ANALYTICAL INSTRUMENT, CREATING LARGE AMOUNT OF DATA THAT BECAUSE OF SOME PROBLEMS SUCH AS STRONG VARIATION OF THE ELEMENTS CONCENTRATION IN ANALYZED SAMPLES AND MUTUAL INTERACTIONS HARDLY BE USEFUL WITHOUT PREPROCESSING [1]. EXPLORING SOURCES OF PRECIOUS METALS IS ONE OF THE MAIN CONCERNS OF GEOMETRICS. STATISTICAL ANALYSIS PROCEDURES CAN PROVIDE VALUABLE KNOWLEDGE FOR FINDING THE ORIGIN OF SUCH ELEMENTS AND INTERPRETATION OF INITIAL DATA [2].METHOD: IN THIS WORK, THE APPORTIONMENT OF AU IN ROCK SAMPLES BY STUDYING ON A COLLECTED DATA FROM SARILAR, AZARBAYEJAN SHARGHI, IS INVESTIGATED. IN ADDITION, THE DISTRIBUTION OF SOME PARAGENETIC ELEMENTS (CU, PB, ZN, AG, SN, MO, AS, SB, BI) IS DETERMINED.RESULT IN PRESENT STUDY, PRINCIPAL COMPONENT ANALYSIS (PCA) IS APPLIED ON A COLLECTION OF DATA CONSIST OF 130 SAMPLES AND LEVEL OF 10 ELEMENTS FOR ANALYSIS AND CLUSTERING. PCA RESULTS DEMONSTRATE A SPECIAL DISTRIBUTION PATTERN FOR SAMPLES. OBVIOUSLY, SAMPLES DIVIDED UPON THEIR GEOCHEMICAL CHARACTERISTICS AND CAN BE USEFUL IN FINDING PROSPECTING TARGETS SUCH AS AU.CONCLUSION: USING A PCA AS A SUPERVISED CLASSIFICATION METHOD FOR ANALYZING THE DATA SET PROVIDE AN INFORMATIVE RESULT OF A RAW GEOMETRICS DATA BY SUMMARIZING THE INFORMATION FROM A LARGE NUMBER OF COMPONENTS. UNFORTUNATELY, PRINCIPAL COMPONENT ARE OFTEN DIFFICULT TO INTERPRET. SO FOR PREDICTING MINERAL OCCURRENCE POTENTIALS AND IMPROVING ITS INTERPRETABILITY, IT WOULD BE BENEFICIAL TO APPLY OTHER CLASSIFICATION METHODS IN PARALLEL.

FUEL CELLS ARE THE ELECTROCHEMICAL DEVICES THAT TRANSFER THE CHEMICAL ENERGY TO ELECTRICAL ONE. OXYGEN REDUCTION REACTION (ORR) WHICH IS PERFORMED IN CATHODE ELECTRODE PLAYS AN IMPORTANT ROLE FOR INDUSTRIALIZATION OF FUEL CELLS. PRECIOUS METALS SUCH AS PT AND PD PRESENTED BEST ELECTROCATALYTIC ACTIVITY AND THE MINIMUM REPORTED OVER-VOLTAGE FOR ORR BUT THEIR APPLICATIONS SUFFER FROM SOME LIMITATIONS. THEREFORE, IT IS URGENTLY REQUIRED TO EXPLORE INEXPENSIVE, NON-PT CATALYSTS FOR THE REPLACEMENT OF PT-BASED CATALYSTS. ONE OF THE POSSIBLE SOLUTIONS FOR THIS PROBLEM IS USING NON PRECIOUS METALS. ORDERED MESOPOROUS CARBON MATERIALS (OMC) ARE HIGHLY ATTRACTIVE FOR APPLICATIONS IN ENERGY CONVERSION DEVICES. MOREOVER, IT HAS BEEN PROVED THAT INCORPORATION OF NITROGEN HETEROATOM INTO CARBON FRAMEWORK ENHANCE THEIR ELECTROCHEMICAL AND CATALYTIC PROPERTIES [1]. A NOVEL NANO-FIBRILLATED MESOPOROUS CARBON (IFMC) WAS SUCCESSFULLY PREPARED VIA CARBONIZATION OF THE IONIC LIQUID 1-METHYL-3-PHENETHYL-1HIMIDAZOLIUM HYDROGEN SULFATE (MPIHS) IN THE PRESENCE OF SBA-15. THE MATERIAL WAS SHOWN TO BE AN EFFICIENT SUPPORT FOR THE PALLADIUM NANOPARTICLE (PDNP) CATALYST PD@IFMC IN AEROBIC OXIDATION OF HETEROCYCLIC, BENZYLIC, ALIPHATIC AND ALLYLIC ALCOHOLS AND HETEROATOM CONTAINING ALCOHOLS ON PURE WATER [2]. CONTINUING OUR PREVIOUS STUDIES ON CATALYTIC AND ELECTROCHEMICAL APPLICATION OF NITROGEN DOPED MESOPOROUS CARBONS, WE WERE ENCOURAGED TO INTRODUCE SOME NON-PRECIOUS METALS, SUCH AS FE, FOR OBTAINING NANO-STRUCTURED CARBON WITH "NITROGEN-METAL SITES" AS EFFICIENT ELECTROCATALYST FOR ORR. ORDERED MESOPOROUS CARBON WAS DERIVED FROM CARBONIZATION OF IONIC LIQUID (MPIHS) AND GUANINE AS A NITROGEN RICH ORGANIC MOLECULE, AS CARBON PRECURSOR, AND ORDERED MESOPOROUS SILICA (SBA-15) AS TEMPLATE [3]. THE STRUCTURE OF OBTAINED OMCS WERE CHARACTERIZED BY TRANSMISSION ELECTRON MICROSCOPY (TEM), N2 ADSORPTION-DESORPTION ANALYSIS AND THERMAL GRAVIMETRIC ANALYSIS (TGA). THE NITROGEN DOPED OMCS THEN FUNCTIONALIZED BY POST-TREATMENT WITH NITROGEN CONTAINING IRON COMPLEXES. THE RESULTING POROUS CARBON MATERIALS HAVE BEEN USED AS AN ELECTRODE MODIFIER AND THEIR ELECTROCHEMICAL PERFORMANCES HAVE BEEN EXAMINED TOWARD ORR. HYDRODYNAMIC AND CYCLIC VOLTAMMETRY STUDIES OF THE METAL-NITROGEN CONTAINING CARBONS HAS BEEN PERFORMED AT VARIOUS PH VALUES AND THE DESIRED STRUCTURE HAVE SHOWN VERY GOOD PERFORMANCE AND LOW OVER-POTENTIAL AT BOTH ACIDIC (0.1 M HCLO4) AND BASIC (0.1 M NAOH) SOLUTIONS. THE DURABILITY OF MODIFIED ELECTRODE BASED ON THESE STRUCTURES HAS BEEN ALSO EXAMINED BY CHRONOAMPEROMETRIC STUDIES AND THE RESULTS CONFIRMED VERY GOOD STABILITY FOR THE OBTAINED MODIFIED ELECTRODES.

Markazi province is located in central of Iran and it belongs to Metallogeny zone of Sanandaj Sirjan and Magmatic zone of Oromieh-Dokhtar.Ancient mining activity in Markazi province shows there are some potential area for PRECIOUS and semi PRECIOUS stone such as Garnet, Tourmaline, Zircon, Quartz, Jasper and so on.A primary exploration improved the existence of these minerals in Khoshgehdar and Ghaleh Agah Hamid in Saraband and also Nezam-Abad in Arak and finally zali-bolagh, Nivasht and Koh-pang in Saveh.About 100 sample collected from the study area and cut and polished in Iran and India.The result shown 1-Tourmaline and Garnet due to their maturity, crakes and colors has not good characteristics for cutting and polishing although there are enough amounts of these stones in the area of Khoshgehdar and Ghaleh Agah Hamid.2-Quartz has a good characteristic for cutting and polishing although there is a good outcrop in the surface but, we do not know about amount of reservoir underground.3-Jasper is the only mineral that has a good condition for cutting and polishing and also has enough reservoirs in Markazi province. According to our researching, although there are enough amounts of these Semi PRECIOUS stones in Markazi province but there is not any recognized market of Jasper in Iran. We should explore, extract, cut and polish Jasper in Iran and then export these production to some country such as U.S.A, Germany, France, Russia and India that has a good market for jasper.
