quick question im using a tablet rn rather then my main computer can you throw me the materials list i want to have a look at it.
-bauxite/limonite would be directly under dirt as well as in swamps this would be somewhat common but realistic as limonite and bauxite are extremely common. Alumina mostly is more of a thing for actual rock so it doesnt matter as much.
-cassiterite/magnetite would exist both on riverbeds, in water as well as in patches in deserts… cassiterite being around 10x rarer just like it is in reality
Garneirite is also a mineral sand it should be around 5x rarer then limonite as in a middle ground
-glauconite/fullers? these could either be rare in generic areas or common in deserts and swamps
rare gem sands whether diamonds/sapphires/topaz/thaum/Beryl giving random results in sifter
summary of Bauxite/Limonite/ Garneirite/Cassiterite out of 100
Bauxite(45%) 4%(dense alumina) 1% sapphire sand (50)
Limonite(brown 9%/orange 9%/ yellow ) 1% each hematite/Olivine/magnetite (30)
Garneirite( 10% of all mineral sands)
Cassiterite (5% of all mineral sands)
Gem Sands (5% altogether mineral sands… includes each gem type seperately)
Giving it a sort of relative rarity works… note glauconite would be around garnierite in how common it is and quartz sands would be around probably be at least 3x more common then Bauxite (and considering it would look exactly like cassiterite pretty much could make it far harder to see
