ELEMENT GEOCHEMISTRY OF ZHIJIN PHOSPHORITES,GUIZHOU PROVINCE

Acta Mineralogica Sinica (2006)

Shi Chun-hua Ruizhong Hu

Phosphorites from the Gezhongwu Formation in Zhijin County consist mainly of bioclast dolomitic and siliceous phosphorite.They generally show bioclast structure and are made mainly of small shelly fossils and alga fossils.The trace element and REE contents of phosphorites were analyzed by Finnigan Mat Element high resolution ICP-MS.The results of analysis suggest that the phosphorites are rich in As and Sb;the ratio of Co/Ni is 0.14 and the value is less than 1;the ratio of U/Th is between 1.27 and 7.39,the average is 3.40;the sample is located in the field of the hydrothermal sediments on the plots of lgw(U)-lgw(Th) and Cr-Zr,which indicates the phosphorites were deposited in hydrothermal environments.The phosphorites are rich in REE,especially Y,the total REE concentrations are high.The Zhijin phosphorites show negative Ce anomalies,indicating that marine depositional environments are oxic.PAAS-normalized REE concentrations plotted against respective atomic numbers are characterized by slight MREE enrichment,showing hat-shaped REE patterns.The patterns suggest that fauna played an important role in phosphorite formation.The phosphorites are characterized by positive Eu anomaly,high ∑REE and high ∑LREE/∑HREE ratio,suggesting that Zhijin phosphorites are of normal marine deposition plus hydrothermalism origin.

Geochemical constraints on the origin and environment of Lower Cambrian, selenium-rich siliceous sedimentary rocks in the Ziyang area, Daba region, central China

International Geology Review (2011)

Caixia Feng Guoxiang Chi Jiajun Liu Ruizhong Hu Сhen Liu

The Ziyang area is one of the two major regions of central China subjected to selenium (Se) poisoning. Systematic studies of Se contents of different lithologies from this area indicate that Lower Cambrian, carbonaceous, and siliceous strata host the highest Se contents (with Se contents of up to 278 ppm). We have investigated their geochemical characteristics (major and trace elements, and Si and O isotopes), origin, and sedimentary environment of formation. The siliceous rocks are characterized by a wide range in major elements, and are enriched in Se, Ba, Cu, Ni, V, As, Sb, and U relative to average continental crust. They are also enriched in light rare earth elements relative to heavy rare earth elements (LaN/YbN = 1.64–35.7) and show weak or moderate negative Ce anomalies and strong positive Eu anomalies. δ30SiNBS-28 and δ18OV-SMOW values range from –0.3‰ to 0.6‰ and 16.1‰ to 21.7‰, respectively. The homogenization temperatures of inclusions within the studied samples range from 113°C to 319°C, and their salinities from 1.2 to 13.7 wt.% NaCl equivalent. Our results suggest that the studied siliceous rocks resulted from hydrothermal sedimentation in a relatively anoxic semi-deep sea sedimentary environment. The hydrothermal fluid responsible for Se-mineralization involved the mixing of low-temperature high-salinity fluid, low-temperature low-salinity fluid, and a high-temperature low-salinity basinal fluid in the NaCl–(KCl)–H2O system.
