·The Tiemurt Pb Zn Cu deposit metal reserve Mt Pb Zn and Mt Cu is hosted in the Kangbutiebao Formation volcanic sedimentary rocks in the Chinese Altay Orogen NW China Although some geological and geochemical characteristics of primary seafloor sedimentary mineralization are preserved major fault controlled Pb Zn Cu orebodies
·Trace element concentrations in C rastrospinosus in the northern Antarctic Peninsula were ordered from high to low as Zn > Cu > Cd > Pb in the intestine Zn > Cu > Pb > Cd in the stomach Zn > Cu > Cd > Pb in the liver and Zn > Cu > Pb > Cd in muscle Zn content was significantly higher in all tissues by at least one magnitude than other
·An example is the Zn Pb Ag Cu Bi mineralization at Cerro de Pasco and Cu Zn Pb Au Ag mineralization in the Colquijirca district of Peru which are thought to be located in the upper parts of Cu bearing porphyries Baumgartner et al 2008 Bendezú and Fontbot 2009
·The concentrations of Cu Zn Pb Cd and As varied quite differently in the water suspended particulate matter SPM and sediment along the middle reach of the Beijiang River in southern China The total concentrations of trace metals and As in the water column were significantly affected by the concentration of SPM while the metals and As in the sediment
·The spatial distributions of Cr Ni Cu Zn As Cd and Pb potentially toxic elements PTEs in sediments and intrinsic influence factors from the Wuliangsuhai wetland of the Hetao Irrigation District China were studied in this work The results showed that excluding Zn the total contents of other PTEs were higher than the background values of which As
·The Pb Zn Cu mineralization was likely associated with hydrothermal fluids that exsolved in the late magmatic crystallization and extracted ore forming materials in the wall rock two mica monzogranite whereas the pegmatites were differentiation products of the two mica monzogranite
