The Sanqingshan Geopark is situated in the northeastern Jiangxi province, which is a boundary area between Yangtze and Huaxia terrains. The Sanqingshan granite with an area of 98 km2 is a part of Huaiyushan intrusion within a larger area. Based on their contact relationship, it can be divided into three stages (from early to late): middlecoarse grained biotite alkalifeldspar granite, middlegrained biotite alkalifeldspar graniteand grained biotite alkalifeldspar granite respectively. The second stage of granite is the largest one in the geopark, and most of the tourist views are concentrated in it. The SHRIMP UPb zircon dating for the second and third stages yield ages of 123±2.2 Ma and 115.6±2.0 Ma respectively, which are later than the mineralized granitic rocks in the northeastern Jiangxi. All three stages of granites have similar mineralogy and geochemistry. They are composed of biotite, feldspar, albite (An<8%) and quartz, with hole structures, and they are characterized by high Si ( >75%) and alkali (7.7%~8.8%), low Ca (<1%) and high FeO*/MgO (11~54). They also have relatively higher REE (except for Eu) and high strength field elements such as Zr, Nb and Ta concentrations, but lower Sc, Cr, Co, Ni, Sr and Eu concentrations. In addition, they have high Ga/Al (3.3~4.0), characterizing A typegranite, neither I nor S types of granite. On the geochemical discrimination diagrams, they can be classified into A2 type, and formed during postorogenic movement. They originated from continental crust with about 10 km depth, and intruded around 6 km under the temperature of 850~900℃.
