This embedded authentic research project in mineralogy course allows students to engage in a range of analytical methods to prepare a consulting report for Tintina Resources. The project covers professional standards, sampling, lab protocols, data fidelity, and writing skills. Components include literature review, field trip, sample preparation, X-ray diffraction, SEM/BSE/EDS, compositional analysis, and the submission of an integrated consulting report.

Embedded Authentic Research Project in a Mineralogy Course(LEARN SCIENCE BY DOING SCIENCE) David W. Mogk Dept. of Earth Sciences Montana State University
Characterize the mineralogy of the Black Butte Cu-Co Deposit, Montana • Students engage a range of analytical methods to prepare a consulting report for Tintina Resources • Professional standards • Sampling • “Chain of Custody” • Lab protocols; cleanliness; safety • Documentation, lab notes, annotation of figures… • Fidelity of data (processing, representation) • Writing (data/observation v. interpretation; citation) • Group work; responsibility to project
Project components • Literature Review • Field trip to project site; interaction with staff exploration geologists • Sample selection from drill core; host rock and sulfide zone • Sample preparation • Cut and polish billets; crush and powder samples for random and unorientedXray diffraction; Chain of custody—log in all actions done to samples • XRD • Whole rock mineral content; quantitative XRD • Clay Mineralogy • SEM/BSE/EDS • Identify primary and seconary ore minerals • Image textures; grain size, overgrowths… ( to inform metallurgicial studies) • Compositional analysis; pure end members, solid solution; Where is the Co? As? • pXRF (Major and trace element) • Metal credits (Cu, Co, Ag)….Correlation of metals with S.... • Major elements: provenance, diagenesis • Integrated Consulting Report submitted to sponsoring company; Tintina Resoures
