Abstract Taking No.50 kimberlite pipe of Wafangdian diamond deposit in Liaoning Province as an example, the authors systematically analyzed its geological characteristics. Based on the petrogeochemical analysis of porphyry phlogopite kimberlite, breccia porphyry kimberlite with surrounding rocks and kimberlite tuff breccia, it is found that there are less ultrabasic components in carbonated kimberlite tuff breccia and more ultrabasic components in kimberlite tuff breccia mixed with steatitization, serpentinization and carbonation. The content of Cr, Ni and Ti is relatively lower in kimberlite tuff breccia, slightly higher in breccia porphyrg phlogopite kimberlite with surrounding rocks and the highest in porphyry phlogopite kimberlite and porphyry kimberlite. This deposit is mainly composed of breccia porphyry kimberlite with surrounding rocks and porphyry phlogopite kimberlite, followed by kimberlite tuff breccia, breccia porphyry phlogopite kimberlite with surrounding rocks and kimberlite breccia. Chromite bearing pyrope, chromite and moissanite are associated minerals of the diamond deposit. The kimberlite ore-bearing grade is high in the western part and low in the eastern part in the horizontal direction, while the kimberlite ore-bearing grade changes little in the vertical direction. Through the three-dimensional modeling, it is inferred that instead of the root phase, No.50 kimberlite pipe is the fault dislocation caused by the EW nappe structural force with the No.50-1 kimberlite body at the depth of 600 m in the eastern pipe.

Key words： No.50 kimberlite pipe deposit characteristics diamond deposit Wafangdian of Liaoning Province
