Apatite is a material from the Forestry mod. This material is found in large, uncommon veins above sea level, or above Y level 60. It is used to make fertilizer for Forestry farms. When the ore is mined, it will drop a few Apatite gem items. Originally, Apatite was present in Biomes O' Plenty, but has been renamed to Malachite to avoid confusion with Forestry's Apatite.

Veins can range in size from 16x16x5 up to 80x80x8 blocks, with very few and small gaps between ore blocks. However, ore veins can only generate where they have Stone, Red/Black Granite, Netherrack, or End Stone that can be replaced by ore blocks. Mix Veins come in four parts: Primary, Secondary, Inbetween, and Around.

Apatite Ore is an ore added by the Forestry mod. It is based on a phosphate mineral and is primarily used to create Fertilizer . Apatite Ore only generates on layers 64 and above and is therefore most commonly found in mountainous biomes, hills and exposed cliffsides. Apatite Ore spawns in very large veins of often over 20 blocks in size.
