·The second group of mineralizations developed within the carbonate rocks of Eocene Oligocene aged Midyat Group and is further divided into subgroups as barite and Pb Zn bearing barite mineralizations These mineralizations generally occur in vein structures along N30 50°E and vertical fracture zones
·The Precambrian sedimentary volcanic sequence of Kahar Formation KF located in the Mishu mountain NW Iran hosts numerous strata bound and stratiform Barite Pb Cu Zn deposits
·Request PDF Effective procedures for the determination of As Cd Cu Fe Hg Mg Mn Ni Pb Se Th Zn U and rare earth elements in plant and foodstuffs There are several international
·Total concentrations of Cu Pb As Cd Zn Fe Ni and Mn were determined for 81 soil samples using two types of field portable X ray fluorescence FPXRF system; dual isotope and X ray tube
·Comparison of features of the Barite Pb Cu Zn deposits of the Mishu mountain with the principal characteristics of SEDEX mineral systems based on Leach et al 2005 are presented in Table 7 Characteristic features of the Mishu deposits including their occurrence within a sedimentary sequence strati form and strata bound ore bodies
·Potato tubers were planted in plastic vessels filled with Zn Pb Cu and Cd contaminated soil and grown in a greenhouse Three of these vessels were treated with direct current electric field DC three with alternative current AC and three remained untreated as control vessels
·Metallogenesis of Precambrian SEDEX type Barite Pb Cu Zn deposits in the Mishu mountain NW Iran Constrains on the geochemistry and tectonic evolution of mineralization
·The barite Pb Cu Zn mineralization at Mishu mountains is composed of strata bound and stratiform ore bodies These occurrences include Aralan Pyrbala Almas Shanjan and Daryan which are hosted by a late Precambrian sedimentary sequence of the Kahar Formation organic material bearing shales siltstones and fine grained sandstones
·About Pb Cu Lead and zinc are extremely close in nature especially in primary deposits and often coexist Most of the lead zinc minerals are sulfides and sulfates and galena and sphalerite are the primary Pb Zn ores Non sulfide It is formed due to hypogene and supergene weathering Mostly oxide ores like zincite and cerussite may fall under this category
