## Appearance

The Amphibolite is a dark rock, typically appearing black or deep greenish-black, sometimes with a greyish hue. It often has a speckled appearance from its mineral crystals and can show a subtle banding due to mineral alignment.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Ancient civilizations used tough amphibolite to make tools and weapons because it was so strong and durable.
- Even though it looks plain, amphibolite can sometimes hide valuable ores like gold, waiting to be discovered!
- Imagine rocks changing into amphibolite deep underground without melting, like playdough under giant pressure!
- Some of the oldest parts of continents contain huge amounts of amphibolite, telling tales of early Earth!

## Special abilities

- **Building Block Power:** Amphibolite has high durability and resistance to weathering that makes it a long-lasting material for construction and architecture.
- **Deep Earth Detective:** Amphibolite forms under intense heat and pressure, allowing scientists to uncover clues about Earth's deep geological processes.
- **Shiny Gem Host:** Amphibolite can host beautiful minerals like garnets or epidote within its dark matrix, making it a source of decorative stones.

## Measurements & details

- **Color Range:** dark green, black, greyish-green
- **Hardness:** 5.5
- **Luster:** vitreous to dull
- **Specific Gravity:** 3.1

## Traits

- [Metamorphic](https://www.snappit.app/explore/traits/metamorphic): Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemical alteration.
- [Crystalline](https://www.snappit.app/explore/traits/crystalline): Crystalline describes a mineral or rock composed of crystals, often exhibiting a regular atomic structure and geometric external form.

## Safety

**Danger:** 1/5 · Very low

Amphibolite is a rock and not a living organism, so it is safe to observe and touch.
