Mar Mar's Enhanced Ore Variety
by MarMarDev
Mar Mar's Enhanced Ore Variety changes which ores generate in the world, adding new variants of vanilla ore blocks, including emerald, to the stone types players dig through.
What it does
Vanilla ore generation tends to repeat the same few ores in each stone layer, which can make exploration feel samey. This mod alters the generation so that the ore types found in a given area are more varied. New ore variants are added for the vanilla blocks, and the stone types granite, diorite, andesite and tuff are covered as well, so a single cave can hold several kinds of ore.
The new ores are placed in the same way Mojang's own ores are, so the generated terrain follows the usual vanilla patterns rather than looking like an add-on. The mod runs on client and server, so a server and every player need it installed. It is published for Fabric, Forge and NeoForge, with builds covering 1.20.1 – 26.3, and the code is released under the MIT License, which makes it open source. Create Fillers requires it.
Key features
Varied ore generation
Ore types are spread more evenly through each stone layer, so one area no longer shows the same few ores.
New ore variants
Variant ores are added for vanilla blocks, including emerald, giving new blocks to collect and place.
Stone type coverage
Granite, diorite, andesite and tuff stones also receive ore variants, extending the changes beyond standard stone.
Vanilla-style placement
New ores generate with the same placement logic as Mojang's ores, so the terrain looks natural.

Use cases
Modpacks and long worlds

Who it’s for: Players who want ore distribution to differ from vanilla, and modpack authors looking for ore variety that fits existing terrain.
How it compares
Seamless Ores is client and server, uses a custom license, is not open source and covers 1.20 – 26.3 on Fabric, Forge, NeoForge and Quilt. No More Stone Variants is server-side only, released under the MIT License, is not open source and covers 1.19 – 1.21.1, so the server needs it and players may add it. Create: Universal Ores is open source under the MIT License, with Fabric builds for 1.20.1 only.
