Structure and Density of Sedimentary Basins in the Southern Part of the East-European Platform and Surrounding Area

Round 1

Reviewer 1 Report

Dear authors,

Undoubtedly, this is very interesting and actual investigation. Without hesitation, this MS must be accepted for publication. However, there are some minor remarks.

(1) Practically in all maps is written "Great Caucasus" instead correct "Greater Caucasus).

(2) The authors refer for the rock density to 'Shengelaya, G.Sh. Gravity model of the Caucasus’ crust. Nauka: Moscow, USSR, 1984, pp.31–58 (in Russian).'

However, it is sufficiently old publication. A lot of rock density investigations has been performed during the following periods. One useful chapter from the book (2012) on the Caucasus is attached.

Dear Reviewer,
First of all thank you for a review of our manuscript and valuable comments and recommendations that helped to improve it.

On your comments:
"(1) Practically in all maps is written "Great Caucasus" instead correct "Greater Caucasus)."
Yes, indeed, that needed to be corrected. I've changed "Great Caucasus" to "Greater Caucasus" in all maps in the new version of the manuscript.
"(2) The authors refer for the rock density to 'Shengelaya, G.Sh. Gravity model of the Caucasus’ crust. Nauka: Moscow, USSR, 1984, pp.31–58 (in Russian)"
- Thank you very much for the book chapter. I've referred for (Khesin and Eppelbaum, 2007) mentioned in the book chapter focused on density modeling, now the publication [61] in the reference list is the following:
61. Khesin, B.E.; Eppelbaum, L.V. Development of 3D gravity/magnetic models of earth's crust in complicated regions of Azerbaijan. In Proceedings of the Symposium of the European Association of Geophysics and Engineering, London, UK, 11-14 June 2007; European Association of Geoscientists & Engineers: London, UK, 2007; P343, 1–5. https://doi.org/10.3997/2214-4609.201401966.

Reviewer 2 Report

Dear Authors.

First of all, I would like to thank you for the authors for their work and dedication in carrying out this study. The article entitled: „Structure and density of sedimentary basins in the southern part of the East-European platform and surrounding area“ is very interesting. The study area of this manuscript is the sedimentary areas in the southern part of the EEP and adjacent areas, including the Caucasus. The results in the study present a new sediment model using an approach based on decompensation of gravitational anomalies. It is well documented, has many bibliographic sources of great importance and relevance for the subject in question and fits the theme of the journal.

It is necessary to check the English and typos in the text (in line 170: "cgaracterized", in line 311: "1. 1. It is ...", etc.)

I recommend adding degrees in all figures to the values on the axes (20°-60°, 40°-50°).

I recommend unifying the size of figure number 2 - 8. Figure number and its width in cm: no. 2 - 6.2 cm; 3 - 6.8; 4 - 7.1; 5– 7.0; 6 - 6.8; 7 - 6.6; 8 - 7.

Best regards

Dear Reviewer,

"It is necessary to check the English and typos in the text (in line 170: "cgaracterized", in line 311: "1. 1. It is ...", etc.) "
- Spell check is done, typos are fixed: line 102, 170, 190-191, 311, 388, 458. Also some terms changed in line 175: "Miocene (Sarmatian and Tortonian) changed to "Upper Miocene", as Sarmatian age in Miocene is a Russian specific name coresponding to Messinian age. I just decided to make the statement simple.

"I recommend adding degrees in all figures to the values on the axes (20°-60°, 40°-50°)."
Degree signs are added in the new version.

I recommend unifying the size of figure number 2 - 8. Figure number and its width in cm: no. 2 - 6.2 cm; 3 - 6.8; 4 - 7.1; 5– 7.0; 6 - 6.8; 7 - 6.6; 8 - 7.
The size of figures has been unified for Fig. 2-8 (7 cm) in the new version.
Also the unnecessary (a) and (b) captions have been removed from the rasters, as there are already (a) and (b) captions in the figure tables.
Best regards,
