Ningwu volcanic basin is one of the important deposit-intensive areas along the Middle-Lower Reaches of Yangtze River metallogenic belt. Apatite is one of the key diagnostic minerals for a variety of deposits in this area. Taking the Taocun iron deposit, one of representative porphyrite irons in Ningwu Basin, as an example, this study examined trace elements and major elements compositions of the apatites (Ap-I, Ap-D, Ap-V) from pyroxene diorite porphyrite, disseminated magnetite ores and using electron microprobe and LA-ICP-MS methods. The results show that the apatite (Ap-I) from pyroxene diorite porphyrite and apatites (Ap-D and Ap-V) changes within a small range in compositions, suggesting they are fluorapatite with minor S and Cl. But the apatite (Ap-I) contains higher contents of Na, Mg, Si, V, Mn, Fe, Ga, Ge, Sr, Y, Zr, Ba, REE, Pb, Th, and U.
