This paper put forward two questions about “Petrogenesis of the highly fractionated granites and their mineralization in Nanling Range” by WU Fuyuan et al. （2023）published in Acta Petrologica Sinica, volume 39, issue 1: (1) Extensive early Yanshanian granites in the Nanling Range constitute the main intrusive phase of granitic complexes. Based on the evidence of three mantle- derived materials（basalt, microgranular enclave and basic vein）, WU Fuyuan et al. （2023）believes that these granites are the products of crust—mantle interaction. This paper argues over these lines of mantle- derived evidence, and proposes that the early Yanshanian granites in the Nanling Range are syn- orogenic granites (main intrusive phase) that were emplaced along crustal shearing—compressive fault in the forceful mechanisms. (2) WU Fuyuan et al. （2023）believes that the subsequent intrusive phase（small stock）in these granitic complexes is also the early Yanshanian, and should be the highly differentiated product of the main intrusive phase with the same origin. This paper emphasizes that the initial granite magma must undergo more than 20 Ma of fractional crystallization in the deep magma chamber under the gravity and heat convections, and then it is possible to form residual magma with huge amount of ore- forming minerals in the upper part of the magma chamber. In the early Cretaceous extensional environment, these residual magmas rapidly intruded in the permissive mechanisms, and would split into two portions: one forming magmatic—hydrothermal deposit and another forming the subsequent intrusive phase（i. e., post- orogenic granite）respectively.
