The manuscript “Genesis of hydrothermal gold mineralization in the Qianhe deposit, central China: Constraints from in situ sulfur isotope and trace elements of pyrite” written by Feng et al., detailed field investigation, microstructure observation and petrographic study were carried out to identify the different generations of pyrite in the Qianhe gold deposit. By means of in situ LA-ICP-MS trace elements and sulfur isotopic analyses, the sources of hydrothermal fluid and ore-forming material were elucidated. the manuscript might be suitable for publication in Geological Journal after minor revision. I list my comments below:
1. Many wall rock alterations and gangue minerals are described in this paper, which may be added to the corresponding photographs;
2. The values of some elements such as Ti, Co, and so on vary too much. The authors should check this carefully;
3. The “Disscussion 6.1 Trace element characteristics of pyrite”, Line 343, the galena inclusions are the primary form of Pb distribution in pyrite, Pb-bearing inclusions are observable mainly in Py2, and the Pb content is high; What is the cause of the high Pb content in Py1 and Py3?
4. In line 359, We cannot see the parallel distribution patterns of Co, Ni in the LA-ICP-MS time-resolved depth profile.
