Background to Geology Practical Online Study Guides
What/Why?
I designed these online study guides like a toolbox with resources that may be re-purposed for different learning objectives.
media-rich resources for online, observational, lab activities in the identification of minerals, igneous, sedimentary, and metamorphic rocks
includes a collection of known (identified in the visual bank) samples with reference properties
includes a collection unknown (unidentified) samples undergoing traditional tests (e.g., HCl, Mohs, streak)
includes a new electrical conductivity test using a cheap flashlight for identifying metallic minerals
includes links to external resources (e.g., extensive image banks)
Web Features
free, public, web-accessible
delivery to (almost) all devices,- cellphones , laptops, desktops
viewable through (almost) all browsers, but Chrome might generate the fewest issues
Use Cases
as a supplement to textbook or other online resources
as a training aid for learning to make relevant observations
as an out-of-class resource for practice and review prior to a quiz or report

This is the first iteration of "Mineral Identification - A Practical Online Study Guide", and I can guarantee the presence of typos / errors, omissions and even bad web design.

To Students: Your Lab Experience, In-Class or Online
In-class lab with physical samples
Your instructor may have provided you access to this website to supplement your in-class study of minerals and their identification. You may find this site useful in different ways:
as a training aid through videos and images for learning to perform physical examination and simple tests, such as the streak test, the acid test, etc.
as a supplement with images and video snips to your examination of physical samples
as an online resource for characteristic mineral properties compiled in the Mineral Bank
as an out-of-class resource for practice and review prior to a quiz or report
Online self study or review
Your instructor may have provided you access to this website for a number of different purposes, including, but not limited to the following.
as a primary resource for learning how your online observation of simple tests and experiments produce distinct results that can be visually assessed and recognized
as an online resource of digital assets for which characteristic mineral properties can be ascertained and used for identification
as an online resource for practice and reinforcement of the procedures for mineral identification
To Students: Instructions
This study set consists of a smaller set of minerals drawn from a limited bank of common minerals. Additional minerals may be added in the future to both the study set and the bank.
Review Testing Minerals to learn how to observe online images and video for characteristic properties of minerals
Access unidentified mineral samples in the Unknowns.
Make notes and record observations. Print and use this Data Form, or one issued by your instructor.
Compare your recorded observations with an identification chart in your textbook or other resource, OR consult this limited bank of identified minerals with relevant properties.
Identify the unknown mineral samples by name by comparing your recorded observations with an identification chart and this limited bank. An unknown sample is identified when its properties most closely match those of a mineral identified and described in the limited bank or your external resource.
CAUTION. Some links to online resources outside of this website will display content in a new browser tab. Some links will be accompanied by advertisements. The value of the displayed content outweighs the distraction that may be caused by ads - so IGNORE ADS!
To Students: Learning Objectives
Primary learning objectives for the student study of mineral properties and identification include, but are not limited to, the following.
For example, you will learn to
perform simple tests or experiments - for example, the "acid test", the hardness test, the streak test, the electricity conduction experiment, OR
observe and understand simple tests or experiments that reveal characteristic properties of samples used for identification
observe a mineral and describe observational facts - for example, "the sample creates a scratch in a glass plate"
recognize and identify an observational fact with a mineral property - for example, "the testing of a mineral against a glass plate is a test of relative hardness on the Mohs scale"
make inferences based on test results - for example, "because the sample creates a scratch in a glass plate, it's relative Mohs hardness must be greater than about 5.5"
identify a mineral by name, based on a unique collection of properties - for example, "because the sample scratches glass, exhibits a pattern of fracture called 'conchoidal', and doesn't produce a streak, these limited properties coincide with those of the mineral quartz as described in my textbook table - so I'll conclude that this sample is made of quartz".
What This Resource Is Not
Not an exhaustive guide to all minerals, common and rare.
Not a collection of assets fully developed for use in mineral identification independent of a textbook or other teaching resources.
Not an authoritative archive of expert information.
Not a finished work.
