21. Mars Pathfinder - Science Results - Mineralogy And Geochemistry Summarizes the geochemical results obtained by NASA s Mars Pathfinder mission. Includes plots of geochemical trends, and comparisons with earlier Viking http://mars.jpl.nasa.gov/MPF/science/mineralogy.html

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.

Materials like this are examined in order to study the evolution of the lithospheric mantle underlying the North China Craton. Evidence suggests that the ancient lithospheric mantle that underlay China as late as the Ordovician has been replace by younger mantle represented by the rock shown.

This approximately 3.85 billion year old rock and other lunar breccias formed by the massive impacts that generated the large lunar basins are studied in order to better constrain the chemical characteristics of planetesimals that impacted the Moon and Earth at that time.

We will discuss practical and theoretical geochemistry, with an emphasis on how chemical principles are used to study Earth Sciences. The course is composed of a three modules: (a) geochemical fundamentals; (b) natural and anthropogenically perturbed aspects of the Earth's hydrosphere and its interaction with surficial rocks, sediments, soils, the biosphere and the atmosphere and (c) the origin and evolution of Earth (crust-mantle-core) and the solar system through nuclear and high temperature chemical processes.

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
