Granite

Granite is a light-colored intrusive igneous rock formed by the slow cooling of silica-rich magma. Because of the slow cooling, grains have more time to grow, becoming visible to the naked eye. Most common rock on Earth's crust and in the mod.

If a Granite is broken by a Geologist Hammer it drops a common cobblestone and the possible minerals to drop are:

Common (> 20%)


 * Quartz
 * Feldspar
 * Biotite

Uncommon (10% < x < 20%)


 * Casseterite

Rate (< 10%)


 * Wolframite
 * Spodumene

Very rare (< 1%)


 * Torbernite

Granite, if broken by a pickaxe, drops the granite block itself unless it's a granite with a specific mineral deposit as:


 * Casseterite in Granite
 * Torbernite in Granite
 * Spodumene in Granite
