Fun Coal Fact:
In 1918, coal miners marveled at a petrified tree stump encapsulated in a coal seam, a vivid reminder that coal is more than just fuel - it's a preserved piece of our planet's ancient past.

The process of vegetation being preserved in a coal seam, such as in the case of a petrified tree stump found by coal miners, is an interesting phenomenon rooted in geological and biological processes. Here's an overview of how it happens:

1. Formation of Peat: Initially, plant material, such as trees, ferns, and other vegetation, accumulates in swampy or wetland environments. This plant matter doesn't fully decompose due to the anaerobic (low oxygen) conditions in these wetlands.

2. Burial and Compression: Over time, layers of sediment, including mud and sand, bury the plant material. As more sediment accumulates, the weight compresses the plant material underneath.

3. Chemical Changes and Coalification: Under the pressure and increased temperature from the overlying sediments, the plant material undergoes chemical changes. This process, known as coalification, gradually converts the plant material into coal. During this process, water and volatile substances are driven off, and the carbon content increases.

4. Preservation of Vegetation Structure: In some cases, the conditions are just right to preserve the structure of the original vegetation within the coal seam. This can include leaves, bark, and even whole tree stumps. The process of petrification, where the organic material is replaced with minerals, can also occur, further preserving these structures.

5. Discovery in Mining: When miners excavate coal seams, they occasionally uncover these preserved pieces of ancient vegetation, providing a direct and tangible link to the Earth's geological and biological history.

This preservation offers a window into the past ecosystems and environments, showing us what was present millions of years ago when coal was formed.

The oldest playable instruments are red-crowned crane-bone flutes from China’s Neolithic Age and in Tibet thigh-bone trumpets (rkangling) and skull drums (damaru) were used.

Multi-colored TOURMALINE...and NOT watermelon tourmaline.

Still worthy of mouth watering.
