Organic Geochemistry Research Group 4821 Quail Crest Place Lawrence Kansas 66049 About the Group The Organic Geochemistry Research Group (OGRG) is a multidisciplinary research group focusing on two important issues. First, is the fate, transport, and degradation of organic contaminants in the environment with special on nonpoint-source contamination from agricultural chemicals. Second, the research objective has been broadened to include the environmental issues of emerging contaminants and how they affect the water. These compounds are combined with analytical methods to determine and link to both geochemical and hydrologic processes.

Hydrothermal Vent Geochemistry Hydrothermal circulation occurs when seawater penetrates into the ocean crust, becomes heated, reacts with the crustal rock, and rises to the seafloor. Seafloor hydrothermal systems have a major local impact on the chemistry of the ocean that can be measured in hydrothermal plumes. Some hydrothermal tracers (especially helium) can be mapped thousands of kilometers from their hydrothermal sources, and can be used to understand deep ocean circulation. Because hydrothermal circulaton removes some compounds from seawater (e.g. Mg, SO4) and adds many others (He, Mn, Fe, H2, CO2), it is an important process in governing the composition of seawater.

Mars Pathfinder Science Results The Alpha Proton X-Ray Spectrometer on the rover measured the compositions of nine rocks. The silicon content of some of the rocks is much higher than that of the martian meteorites, our only other samples of Mars. The martian meteorites are all mafic and ultramafic igneous rocks, volcanic and intrusive rocks that are relatively low in silicon and high in iron and magnesium. Such rocks would be expected to form by partial melting of the upper mantle of Mars. The melt rises up though the crust and solidifies at or near the surface. The mafic volcanic martian meteorites, referred to as basalts, are the most common rock on Earth and have also been found on the Moon. Based on the composition of the martian meteorites and the presence of plains and mountains that look like features produced by basaltic volcanism on Earth, geologists expected to find primarily basalts on Mars. for the bumpy textures is weathered lithic fragments and crystals in volcanic rocks.

The studies of radiometric dating and geochemical reference samples conducted in this department are indispensable for many geological researches. Useful data for environmental and exploration work are provided through the applied geochemical research on the abundance and behavior of elements, isotopes and organic compounds in soils, rocks and minerals. Analytical Methods GSJ develops analytical methods of determining the chemical and isotopic composition of rocks, minerals and other natural materials. They include Atomic Absorption Spectrometry (AAS), X-ray Fluorescence Spectrometry (XRF), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), ICP-Mass Spectrometry (ICP-MS), Instrumental Neutron Activation Analysis (INAA), Thermal Ionization Mass Spectrometry (TIMS) and Secondary Ion Mass Spectrometry (SIMS).

Elsevier Science B.V., Amsterdam. pp. 51-86. 2.1 Introduction 2.2 Fundamentals of Isotope Geochemistry 2.2.1 Definitions 2.2.2 Terminology ... References 2.1 Introduction Of all the methods used to understand hydrologic processes in small catchments, applications of tracersin particular isotope tracershave been the most useful in terms of providing new insights into hydrologic processes. This is because they integrate small-scale variability to give an effective indication of catchment-scale processes (McDonnell and Kendall, 1992; Buttle, 1994). In contrast, internal watershed point measurements, such as those of water level or groundwater composition, cannot be used without extrapolation or additional assumptions about catchment behavior. Isotopes are also "applied" at the watershed scale (i.e., they are within all components of the hydrologic cycle). In particular, O
