One hundred and nineteen samples of clay (n = 42), rock and sand temper (n = 7), and pottery (n = 70) from the various drainages in and around the North Carolina Sandhills were analyzed by instrumental neutron activation analysis (NAA) at the University of Missouri Research Reactor Center (MURR). Here we report the analytical methods and describe some of the chemical patterns identified in the ...

Arsenic occurs naturally in the earth's crust and is widely distributed in the environment. Natural mineralization and activities of microorganisms enhance arsenic mobilization in the environment but human intervention has exacerbated arsenic contamination. Although arsenic is useful for industrial, agricultural, medicinal and other purposes, it exerts a toxic effect in a variety of organisms, ...

Bacteria are remarkable in their metabolic diversity due to their ability to harvest energy from myriad oxidation and reduction reactions. In some cases, their metabolisms involve redox transformations of metal(loid)s, which lead to the precipitation, transformation, or dissolution of minerals. Microorganism/mineral interactions not only affect the geochemistry of modern environments, but may a...

The Jurassic Shaximiao Formation in western Sichuan has made significant contributions to the natural gas reserves and production of China, with many fields successively discovered. accumulation evolution progress discrepant gathering law are continuously improved constantly deepened exploration development. In order find evidence for difference method reshape migration their dynamic processes ...

Fracture-pore complexes, located at fault zones of Darriwilian carbonates, are the main exploration targets in Shunbei area, Tarim Basin. This article focuses on carbonate characteristics Lower Ordovician Well ShunbeiPeng1 (SHBP1), is sandwiched by two trending NW-SE deep-seated, strike-slip faults Shuntuoguole uplift. Based detailed core investigation and careful petrographic examination, rese...

Dongying’s Paleogene geothermal resources are an important part of the Tianjin coastal region. The extent fluid and supply relationship have become increasingly important, will determine whether demand targets can be met. formation in regions is widely distributed to east Cangdong fracture, but it absent west fracture. On basis introducing geological characteristics depositional Dongying format...
