The 3-D geometry of the Linglong granitic complex, Shandong Province, east China, is derived from 2-D gravity forward modeling constrained by geological data. A study of the geometry of the granite body at depth is particularly significant to better understand emplacement mechanisms and to guide gold exploration. The geometry of the granitic complex is analyzed using 2-D gravity forward modeling, constrained by the outcrops of the granites along each modeled profile. Anomalies along the profile were modeled using an interactive program derived from 2-D forward‐modeling techniques. The results show the Linglong granitic complex is a sheet‐like body of 3100 km2 in areal extent and a maximum thickness of 8 km. It is not a deeply rooted batholith as previously inferred.
