Gizmo Mineral Identification: Overview
The Gizmo mineral identification simulation is an interactive tool designed to help students learn about the process of identifying minerals. The simulation provides a virtual environment where students can examine a variety of mineral samples and use their physical properties to identify them.
The simulation’s interface is user-friendly and intuitive, making it easy for students to get started. Key features of the simulation include:
- A library of over 100 mineral samples
- Tools for examining mineral properties, such as color, luster, and streak
- A built-in identification key that helps students narrow down their choices
Mineral Identification Process
The process of identifying minerals involves observing their physical properties and using these properties to match them to known minerals. The most important physical properties used for mineral identification include:
- Color
- Luster
- Streak
- Hardness
- Cleavage
- Fracture
- Specific gravity
By observing these properties, students can narrow down their choices and eventually identify the mineral.
Mineral Properties
Coloris one of the most obvious physical properties of minerals. It can vary from white to black and everything in between. Color is caused by the presence of impurities in the mineral. Lusteris the way a mineral reflects light. It can be metallic, non-metallic, or earthy.
Metallic luster is characteristic of minerals that contain metals. Non-metallic luster is characteristic of minerals that do not contain metals. Earthy luster is characteristic of minerals that are composed of clay or other fine-grained materials. Streakis the color of a mineral in powdered form.
It is produced by rubbing the mineral across a streak plate. Streak is an important diagnostic property because it can help to distinguish between minerals that have the same color. Hardnessis a measure of a mineral’s resistance to scratching. It is determined by scratching the mineral with a standard set of minerals.
The Mohs scale of hardness is a widely used scale for measuring hardness. Cleavageis the tendency of a mineral to break along certain planes. Cleavage is caused by the arrangement of atoms in the mineral. Minerals with good cleavage break along smooth, flat surfaces.
Minerals with poor cleavage break along irregular surfaces. Fractureis the way a mineral breaks when it does not cleave. Fracture can be conchoidal, splintery, or uneven. Conchoidal fracture is characteristic of minerals that break with a smooth, curved surface. Splintery fracture is characteristic of minerals that break with a sharp, jagged surface.
Uneven fracture is characteristic of minerals that break with a rough, irregular surface. Specific gravityis a measure of the density of a mineral. It is determined by dividing the mass of the mineral by the volume of the mineral. Specific gravity is an important diagnostic property because it can help to distinguish between minerals that have the same other properties.
Sample Identification Examples
| Mineral | Color | Luster | Streak | Hardness | Cleavage | Fracture | Specific Gravity |
|---|---|---|---|---|---|---|---|
| Galena | Gray | Metallic | Gray | 2.5 | Cubic | Conchoidal | 7.5 |
| Pyrite | Gold | Metallic | Black | 6 | None | Uneven | 5 |
| Quartz | White | Non-metallic | White | 7 | None | Conchoidal | 2.65 |
| Calcite | White | Non-metallic | White | 3 | Rhombohedral | Conchoidal | 2.71 |
Advanced Identification Techniques
In addition to physical properties, there are a number of other techniques that can be used to identify minerals. These techniques include:
- Chemical tests
- Microscopy
- X-ray diffraction
Chemical tests can be used to identify minerals by their chemical composition. Microscopy can be used to identify minerals by their crystal structure. X-ray diffraction can be used to identify minerals by their atomic structure.
