Hydrothermal Alteration and Its Superimposed Enrichment for Qianjiadian Tabular-Type Uranium Deposit in Southwestern Songliao Basin
Round 1
Reviewer 1 Report
I reviewed the manuscript "Hydrothermal alteration and its superimposed enrichment for Qianjiadian tabular-type uranium deposit in southwestern Songliao Basin" by Quin et al. for a potential publication in Minerals
The article is very well written. The reasearch is very interesting with important novelty such as the use of C and O isotopes, instead to use only the "classical" geochemical major and trace elements
Therefore I suggest to accept this publication as it is.
I only suggest the Authors to check that 13C and 18O are reported with the numbers in superscript (e.g., lines 224 and 225).
Congrats to the authors
Author Response
Dear peer reviewer,
I'm glad to receive your comments and thank for your high appraisal of this manuscript.13C and 18O in the line 224 of the paper were corrected. Some similar error details (such as Ca2+) in my paper have also been revised thoroughly. Thank you very much.
Best regards!

Reviewer 2 Report
Hydrothermal activity associated with uranium mineralization has been studied on the basis of good factual material on the composition of minerals and with the use of modern research methods. The manuscript is recommended for publication.
Minor corrections required:
1. Diabase is an outdated term. It is better to use dolerite or altered dolerite.
2. In the methodics section, the authors should add information about how the CO2 content was determined by the EPMA method.
Author Response
Dear peer reviewer,
I'm so happy to receive your comments of this manuscript. We carried out some corrections as follows: 1) Diabase was revised to dolerite through the paper. 2) The EPMA quantitative analysis method was described in the chapter 3. The details were presented in 3.1 Electron microprobe analysis. Thank you very much.
Best regards!

Reviewer 3 Report
This is a very good and well-written paper on the important subject of formation of sandstone-hosted uranium deposits in large sedimentary basins.
I have only minor suggestions that can be summarized as follows:
Line 66 - sedimentary basins
Line 68 - worldwide uranium deposits as opposed to "domestic and international ore deposits"
Line 84 - the sandstone-hosted ore
Figure 1 caption - please spell out individual deposit names.
Lines 134-135 - what rock types (lithologies) are involved in the pre-Sinian crystalline basement and Paleozoic fold basement? Please specify.
Line 140 - what is the exact age of the "Nenjiang period" for us unfamiliar with the Chinese stratigraphy and geochronology?
Line 141 - "widely overlapped" with what? Please be more specific.
Figure 2 - what is the vertical scale of the profile (b) ?
Author Response
Dear peer reviewer,
I'm glad to receive your comments and thank you for your praise of this manuscript.
These minor constructive corrections were revised as follows:
1) “sedimentary” was added in Line 66.
2) “domestic and international ore deposits” was changed into “worldwide uranium deposits” in Line 68.
3) we add “–hosted” between sandstone and ore.
4) Qianjiadian uranium deposit was spell out in the caption of Figure1.
5) lithologies of the basement composed of genesis, metasandstone, slate, crystalline limestone, phyllite, etc., were describe in Lines 134-135.
6) we provided the ages from ca. 84 Ma to ca. 73 Ma to explain Nenjiang period.
7) the Yaojia Formation and its underlying caprock were widely overlapped by Neijiang lacustrine mudstone.
8) the figure 2a and 2b have been added, and the vertical scale of the profile 2(b) was also presented.
Thank you for your careful review again.
Best regards!
