trace_minerals.renew_minerals (Add trace minerals) bool true

# If enabled, mining stone will occasionally result in a more rare ground node dropping,
# instead of cobble. Such nodes include dirt, sand (all three types), ice, and desert cobble.
trace_minerals.renew_soils (Add ground node upgrades) bool true

# If enabled, coral skeletons and lily pads can be dug up occasionally. Disable this if you want
# a realistic world.
trace_minerals.renew_living (Add fossils) bool false

# If enabled, mining stone will occasionally result not in a drop, but in a liquid pocket. The
# mined stone will become lava or sometimes (if the "valleys" map generator is in use) river
# water. Mining can result in a nasty surprise, as one's torches are burned away and their toes
# singed. Enable this to add a bit of danger.

# Gunpowder is sort of a strange corner case, and there's no one-size-fits-all solution to
# renewing it. The option of how to handle this is left up to the server administrator.
# 
# If set to "None", gunpowder and TNT cannot be renewed, plain and simple. They remain a
# finite resource. In this case, if "Add trace minerals" is enabled, flint can be found in stone
# occasionally.
# 
# If set to "Flint" and "Add trace minerals" is enabled, gunpowder can be renewed through
# flint. Like when set to "none", flint can be found in stone occasionally, and the crafting
# recipe for gunpowder is additionally modified to use flint instead of gravel. In all honesty,
# flint makes a more logical ingredient to gunpowder than gravel does anyway.
#
# If set to "Gravel" and "Add ground node upgrades" is enabled, gunpowder is renewable
# through gravel; the crafting recipe is left unchanged. Instead of flint ever being found in
# stone, occasionally gravel can be found.
# 
# If set to "Flint" and "Add trace minerals" is disabled or if set to "Gravel" and "Add ground
# node upgrades" is disabled, this setting is treated as if it were set to "None".
