pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...
This study was conducted to investigate the effect of canola seed (raw and roasted) and diet concentrate levels on growth performance and quantitative and qualitative characteristics of carcass of Lori male lambs. A total of 54 male 30±0.86kg lambs were selected for the experiment. Treatments consisted of two levels of canola seed (raw and roasted) and three levels of concentrate (60, 70 and 80...
background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...
preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...
Chert concretions in thick limestone successions preserve a more complete paragenetic sequence of diagenetic minerals than their host and interbedded shale. The goal this study was to test the possible presence high-temperature mineralising system Ionian basin western Greece. Upper Cretaceous chert nodules were sampled at Araxos, where rocks are highly faulted uplifted by salt diapirism, on Kas...
Abstract Most of the world's Zn and Pb is extracted from sediment-hosted Zn-Pb deposits. The deposits hosted in carbonate rocks are hypothesized to form by mixing acidic metal-bearing brines with reduced sulfur-bearing fluids while dissolving sedimentary carbonate. To test role this process, we conducted hydrothermal experiments simulating ore formation reacting ± Ba–bearing H2S SO42– produced ...
Located at the intersection of Tethys and Pacific Rim metallogenic belts, Laojunshan polymetallic province in SE Yunnan Province hosts many large-scale W–Sn Sn–Zn deposits. The newly discovered Caiyuanzi medium-sized Pb–Zn deposit is located northern part this has eight sulfide ore bodies. All bodies occur siliceous rocks Lower Devonian Pojiao Formation (D1p). are conformable with stratigraphy ...
