Fd:Frackin'Universe Guide 3

Badlands
You won't find much in terms of plant life here, but you will find ore and minerals. There are most common in deserts.

Blisterbush Field
Well, this is one way to stock up on blister pods on the fly. Useful. Most common on Proto Worlds.

Bloodstone Field
Much like the planet type, Bloodstone Fields are downright strange.

Caliche Field
A great place to stock up on Iodine and Saltpeter by way of Caliche.

Hellfire Field
You'll find tons of Hellfire plants in these small regions. Oh, and lava.

Irradiated Waste
Essentially the same as their planet-size selves.

Lava Lake
Lava. That's...pretty much it.

Meadow
Flowers. Lots of flowers.

Wasteland
A dead expanse of nothing fun or happy. Don't smile.

Pitch
Pitch regions are full of heat, tar and bones. The upside is that they provide abundant oil.

Primeval Forest
Ancient forests loaded with massive trees. A very useful place to stock up on wood.

... and several dozen more!
There are quite literally dozens of other micro biomes to be discovered, loaded with useful resources for your studies. Keep alert and explore!
