Timing of mineralization in the palm of your hand: Cross-cutting relations, copper minerals and ore-forming hydrothermal fluid evolution part of Cutting Edge:Petrology:Teaching Examples
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 evolution of mineralizing fluids that formed the minerals of a copper ore deposit.
Better Living Through Minerals: X-Ray Diffraction of Household Products part of Cutting Edge:Mineralogy:Activities
X-ray diffraction is a quick and valuable tool for identifying minerals. Minerals are an integral portion of our everyday life, in addition to composing our planet! They help bring electricity into our homes and remove our bathtub rings. In this lab, students analyze the X-ray diffraction patterns of three household cleansers, Ajax, White Magic, and Soft Scrub, in order to identify the abrasive minerals in each.
Gestures for Mineralogy: Miller Indices part of Cutting Edge:Mineralogy:Activities
In this exercise, students use one hand to gesture crystallographic axes and the other hand to represent planes designated by Miller Indices. This uses embodied learning to reinforce how Miller Indices are used to convey spatial information.
Modeling Exsolution (and Perthite Formation) as an Example of Complex-System Behavior part of Cutting Edge:Complex Systems:Teaching Activities
Students use a physical model, computer simulation, examples from the natural world, visualizations, and overarching thought experiments to explore this phenomenon. Exsolution embodies attributes of a complex system by exhibiting self-similar features on many scales, and emergent, self-organizing and fractionating properties.
Deciphering complex fluid-mineral interactions in the palm of your hand part of Cutting Edge:Complex Systems:Teaching Activities
This exercise uses polished rock slabs containing veins sealed by copper-bearing minerals to understand the feedback effects in complex fluid-rock systems. By determining the minerals and their relative timing, the changes in fluid composition can be extracted as well as the fracture episodes needed to reopen veins. These palm-sized samples encapsulate complex feedback relations in fluid-rock systems.
