Acid Mine Drainage Field-Lab Experience Round 1 part of Cutting Edge:Geochemistry:Activities
Greg Druschel, University of Vermont and State Agricultural College
This contribution outlines a trip with my Geochemistry class to the Ely Mine, a massive sulfide mine (Besshi-type) in east-central Vermont and the field work they did there. We spent a full day discussing the site, ...
Relationship between mineral weathering and groundwater composition part of Cutting Edge:Geochemistry:Activities
Nancy Hinman, University of Montana-Missoula, The
By observing changes in rocks exposed to chemical weathering, students are to infer resulting changes to the chemical composition of groundwater. Students are required to justify their inferences through the use of ...
Spreadsheet analysis of chemical hydrographs part of Cutting Edge:Hydrogeology:Activities
This is a good activity to have students practice spreadsheet analysis skills on a medium large data set. It also helps them understand stream hydrographs and baseflow/quickflow components.
Timing of mineralization in the palm of your hand: Cross-cutting relations, copper minerals and ore-forming hydrothermal fluid evolution part of Cutting Edge:Courses:Petrology:Teaching Examples
Barb Dutrow, Louisiana State University
This lab is designed to familiarize students with the geologic history of an ore-deposit, deciphered in the palm of your hand. By determining cross cutting relations of veins and mineralogy, students decipher the ...
Using spring water chemistry to understand groundwater inputs part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Rebecca Frus, University of New Mexico-Main Campus
The assignment will begin with teaching proper water collection and use of equipment for hydrochemical field work. Once the class is familiar with sample collecting technques, the class takes a field trip to ...
Dilutions and Spectral Properties of Solutions part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Carmen Nezat, Eastern Washington University
The purpose of this week's lab is to - prepare calibration standards - use a UV-Vis spectrometer to determine the spectral peaks for several dye solutions, and create a calibration curve - calculate how much ...
Analysis of Hydrochemical Data part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Joseph Asante, Oberlin College
In this activity students examine groundwater flow path based on hydraulic head data/ potentiometric surface and spatial variation of groundwater chemistry. Students analyze the data using AquaChem and Phreeqc ...
Batch and Rayleigh Decarbonation Modeling of d13C part of Cutting Edge:Courses:Petrology:Teaching Examples
Jade Star Lackey, Pomona College;
This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes ...
Introduction to Equilibrium Thermodynamics: Salt Dissolution part of Activities
Andrew Knudsen, Lawrence University;
Students dissolve simple salts, halite and sylvite, in water at different temperatures and explore the thermodynamics of this simple system to build a foundation for further studies.
Introduction to urban watershed geochemistry part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Vijay Vulava, College of Charleston
The main goal of this multi-part field and lab exercise is to introduce students to practical aspects of soil and water geochemistry. Some of the analyses for this lab are conducted in the field using field ...
Integrating research methods into geochemistry using local resources part of Cutting Edge:Geochemistry:Activities
Jeanette Jerz, DePauw University
This is a semester-long project that introduces students to research methods and practices. Students learn both field and lab techniques and how to develop testable hypotheses. Using local resources is an easy way ...
