Homework for GLY3850:
Report on the Rock
Name:
This is an individual rock and mineral homework assignment. Each student is required to write a one-page research report about a given rock. You can sign up for a rock on Teams (much like a country); students who haven’t picked one by Wednesday, February 10th will have one assigned to them by me. Igneous, sedimentary, and metamorphic rocks are among the rocks. This assignment is worth a total of 100 points.
Do not begin this task until you have completed all of the lessons in M4.8. It’s due at midnight on Wednesday, February 17th.
The chemistry and mineralogy of your rock, as well as the minerals it contains, must be described in your rock report, as well as where and how the rock formed. This part, however, is critical:
Any words or terms you use that are not part of the vocabulary acquired in this session must be underlined and defined. You don’t need to define a phrase that we’ve used in this class. For example, because you acquired the term felsic in this session, it is acceptable to simply state that granite has a felsic composition. Because you didn’t include the terms “rapakivi” or “orthoclase” in your readings, it’s not acceptable to remark that granite has a rapakivi texture with huge round orthoclase crystals. You must clarify these phrases in your own words if you need to use them.
In reality, you must write everything on your own terms! Plagiarism will result in a class grade of FF.For the rock Granite, here’s an example:
Granite is a phaneritic-textured igneous rock. It’s made up of felsic elements. Quartz, potassium feldspar (also known as orthoclase), plagioclase feldspar, biotite, and amphibole are the most frequent minerals found in granite. Quartz is a silicate framework with the chemical formula SiO2. The framework silicate potassium feldspar, often known as orthoclase, has the formula KAlSi3O8. Plagioclase feldspar is a silicate framework with a composition of NaAlSi3O8 and CaAl2Si2O8. Plagioclase in granite has a high Na content. Biotite is a Fe and Mg-rich trioctahedral layer-silicate mica. Amphibole is a double-chain silicate, and hornblende, a dark-colored mineral-rich in Na, Fe, Mg, and Al, is a frequent variation found in granite. Muscovite, a dioctahedral layer-silicate mica rich in Al, is found in several granites.
Continental arcs developed above subduction zones are rich in granites. When felsic magma cools slowly underground, they develop. Large batholith or stock bodies, such as the Sierra Nevada Batholith of the Idaho Batholith, are common in granites.
[to be provided] ReferencesThe italics words in this example are ones you’ve learned from the readings, whereas the underlined terms are brand new. You don’t have to italicize the words you’re already familiar with, but you must underline and clarify the new words you’ve learned.
You should describe how each mineral in your rock is classified, and you should discuss both the chemistry and structure of silicates (e.g., plagioclase feldspar is a framework silicate with a composition between NaAlSi3O8 and CaAl2Si2O8. Plagioclase in granite is usually high in sodium.)
Your rock report doesn’t have to be as long as this one, and it should contain any references you consulted throughout your research. Any minerals detected in your rock must have their structure and chemistry described in your report.
In a word processing tool, type your report and save it as a file. You’ll copy and paste the report into a Canvas Quiz, which will house all of your homework.Here are your options:
