Early Paleozoic tin mineralization in South China: Geology, geochronology and geochemistry of the Lijia tin deposit in the Miaoershan-Yuechengling composite batholith

•The Lijia tin deposit is formed at 428–430.5 Ma.•This deposit is genetically related to the Lijia granite.•Ore fluids are generated by mixing of 84% magmatic fluids and 16% meteoric water.•Muscovite records the processes of fluid evolution and fluid-rock interaction.•The interaction between the ore-forming fluids and the host granite plays a key role for the cassiterite precipitation.
