- •
Sr, REE and halogens in apatite can track magmas compositions and crystallization history.
- •
The positive correlation of Ga contents with Eu negative anomalies in apatite can indicate oxidation states of magmas.
- •
The combination of Sr/Y ratios and δEu in apatite can identify adakite-like plutons.
- •
Apatite compositions can reveal different magmatic conditions associated with porphyry-type Cu and Mo mineralization, vein-type Mo mineralization and barren mineralization.
