Weathering and Diagenesis


Course Description

Global cycling of major elements. Rock-water interactions. Kinetics of mineral dissolution and growth in soil, marine, freshwater, sedimentary basins and hydrothermal systems. Geochemical models for estimating reaction rates and reservoir capacities/fluxes are considered.

Additional Requirements for Graduate Students:
Term paper or project.


Athena Title

WEATH & DIAGENESIS


Prerequisite

CHEM 1211 and CHEM 1211L and GEOL 3020-3020L


Semester Course Offered

Offered spring


Grading System

A - F (Traditional)


Course Objectives

Students will go into the field every other week to study weathering profiles developed on different parent materials. They will learn to make descriptive observation of soil and saprolite. On alternate weeks students will study chemical and physical processes responsible for weathering at the Earth's surface. Scale of study will start at the atomic level and finish at the global level. Students will understand the exogenic cycling of elements on the Earth.
