Schist Strata

Schist is a type of rare metamorphic rock that forms in thin strata underground. It is known for being extremely rich in resources, making it very valuable to find, despite its rarity.

Formation
Schist strata formation is controlled by a perlin noise function. This means that they are unpredictable to locate, but you are guaranteed to find them at some point.

Utilization
Schist allows for materials to form much more frequently than normal stone. The following materials may be found within it:


 * Gold
 * Lithium
 * Asbestos
 * Copper
 * Iron
 * Rare Earth Elements
 * Petroleum Gas (from Gas Shale, no need for oil processing!)
 * Uranium
 * Scorched Uranium
 * Schrabidium

Schist itself can also be shredded to produce some small amounts of Lithium.

Trivia

 * There is a very low chance that the sine waves cancel each other out and result in little to no strata forming at all.
 * With a new update switching to perlin noise instead of sine waves, this should not happen.
 * Upon mining your first Schist rock, you'll be granted an amount of XP and the "Stratum" achievement.
