The Optical and Spectroscopic Properties of Fuchsite, Spodumene, and Lepidolite from Northern Scandinavia (Kautokeino, Kaustinen, Kolmozero)
Round 1
Reviewer 1 Report
This manuscript cannot be accepted. The main problem is poor and not understandable nonprofessional terminology.
Anyway, I made some corrections for a future:
(1) Geology, microscopic description and discussion should be improved and rewrite
(2) I have several questions: geology and tectonic position of pegmatite bodies, zonation, Influence of host rocks, source, main stages of pegmatite origin: residual melt and hydrothermal solution?
(3) Main references for pegmatites of LCT family: Černý and Ercit (2005), Linnen and Cuney (2005)
(4) Authors confuse the meaning of structure and texture. The structure - general features of the larger constituent parts of the rook developed during its formation (large scale)
The texture is determined by the size, shape, relationship and packing arrangement of different mineral grains (small scale);
In some countries, e.g Russia structure and texture have opposite meaning
Line 39 Archean
Line 40 Crystalline pedestal is not good, maybe basement
Line 43 amphibolite and granulite facies not phases
Line 48 Lithic mineralization should be lithium mineralization
Line 59 One author or all?
Line 96 Table fuchsite, not fuchsyte
Line 105 granitoid
105-106 granitoid and pegmatite intrusion should be granitic intrusion and pegmatite
Line 108-109 texture not structure
Line 110 “specimens” should be aggregates or grains
Line 112 “reticular approximation”?
Line 116 structure
Line 118 Non-transparent, if it is biotite better to use “dark minerals”, because ore minerals are also nontransparent
Line 129 unstructured texture?
Line 131-132 Quartz has wavy (undulose) extinction
Line 131 “In the rock in question” is not good and often repeated, better “studied, investigated, exanimated, etc.
Line 132-133 “highlighted by microcline, usually in the form of vein–like zones and its corners” rewrite
Line 135 “specimens” Under the microscope, should be tabular grains, laths, aggregates
Line 137-138 “crystallizing in its vicinity” rewrite
Line 139 ‘found in gaps” -between.
Line 141 Spodumene forms compact crystals with jagged boundaries in which quartz and muscovite are visible
Line 142 “Accompanying it, hypersthene forms crystals with prominent approximations and striped structures. Non-transparent minerals are present in small numbers in the form of small crystals in the vicinity of quartz, sometimes also forming solid inclusions accompanying zircon” rewrite
Line 151 “pegmatites in question”
Line 151-152 pegmatites are associated with fault activity in the area? Need explanation.
Line 155 dimming wavy -extinction
Line 156 “pseudo-lens character” What is mean?
Line 157-159 “Alongside the tailings are much smaller crystals of acid plagioclase, arranged in a clumped fashion, accompanying the quartz aggregates. In the rock in question, orthoclase, usually reaching considerable size, is also visible in the vicinity of the other leucocratic minerals” rewrite.
“tailings, vicinity” - should be more professional, for example- what is mean in vicinity? Under microscope relationship between mineral grains can be described. It helps to distinguish mineral formation sequence.
Line 164 “specimens”?
Line 165” This pyroxene reaches sizes that macroscopically reach several centimeters”.?
Line 167 “opaque minerals accompanying muscovite flakes” Is it mean that ore mineral is formed together with muscovite or occurs only spatially?
Line 176 mica
Line 198 outliers?
Line 213 andesite is rock, andesine -plagioclase
Line 221 minerals
Line 232-233 “This mineral usually has a light green color, standing out in the rock against a background of quartz and mica”?
Line 235 “diablastic approximations” What is men? Texture?
Line 236 “company of micas”?
Line 239 “darkening obliquely”- oblique extinction
Line 249-250 In the spaces between the flakes, small admixtures of rutile can be seen arranged along the schist?
Line 252 “The mineral dims straight” Parallel extinction
Extinction could be: parallel, symmetrical, inclined, undulose
Line 252-253 “Ripple dimming”
Fig. 6 A- don’t need
Fig.8 what is difference between lepidolite and fuchsite?
Line 383 “residual fluid” what is mean: residual melt, residual liquid
Line 383 “mismatched”- incompatible
Line 386 “surrounding”- host rocks

Author Response
Dear Reviewer, thank you very much on behalf of the authors for their time and review of our text. We admit that it was written in a hurry and we missed many mistakes, for which we sincerely apologize. Our text has been rewritten and we hope you are now satisfied with the new version. We will try to upload it to the system in the next few days. Here are the point-by-point answers to your review:
(1) Geology, microscopic description and discussion should be improved and rewrite
The geology has been supplemented (extended) as well as the microscopic description (corrected) and we have also made thorough corrections in the discussion.
(2) I have several questions: geology and tectonic position of pegmatite bodies, zonation, Influence of host rocks, source, main stages of pegmatite origin: residual melt and hydrothermal solution?
This issue is basically included in the previous one, but yes - we paid attention to this question and described it in the text.
(3) Main references for pegmatites of LCT family: Černý and Ercit (2005), Linnen and Cuney (2005)
We got to these items and got acquainted with them.
(4) Authors confuse the meaning of structure and texture. The structure - general features of the larger constituent parts of the rook developed during its formation (large scale)
The texture is determined by the size, shape, relationship and packing arrangement of different mineral grains (small scale);
The authors have corrected these descriptions throughout the text.

Reviewer 2 Report
I revise the manuscript entitled “Optical and Spectroscopic Properties of Fuchsite, Spodumene, Lepidolite from Northern Scandinavia (Kautokeino, Kaustinen, Kolmozero)”, it is well written and understandable. I have several comments before publishing the manuscript:
1. Kautokeino location is not present in Fig. 1.
2. Defining all the abbreviations when mentioned at the first time, such as: LCT, XPS, FWHM, ……
3. The introduction section is short and without references.
4. Adding scale and altitudes to Fig. 1.
5. Some tables, figures and statements need references.
6. I suggest deleting the term “in question” wherever it is mentioned.
7. The description should be systematic along the manuscript, for example starting with Spodumene then fuchsite and then Lepidolite in all properties and methods.
8. I suggest writing the type of vibrations on the peak of the spectrum.
9. Uniform using either “Figure” or “Fig.” along the manuscript.
10. What about Li in the Spodumene at Table 2A?
11. I have additional comments in the PDF attached file.

- Adding scale and altitudes to Fig. 1. in this drawing we have added the scale, and longitude and latitude.
- Some tables, figures and statements need references. All maps and diagrams have references. In other cases, where there are no references, they are the property of the authors and were created as a result of conducted analyses.
- I suggest deleting the term “in question” wherever it is mentioned. . -we have changed it
- The description should be systematic along the manuscript, for example starting with Spodumene then fuchsite and then Lepidolite in all properties and methods. The authors took note of this suggestion.
- I suggest writing the type of vibrations on the peak of the spectrum. -we have changed it
- Uniform using either “Figure” or “Fig.” along the manuscript. . -we have changed it
- What about Li in the Spodumene at Table 2A? In SEM-EDS, it is not possible to measure the Li content, as the authors have indicated.

Dear reviewer, thank you once again for your concern for the high quality of our publication and for your time. We appreciate your help, authors.
Reviewer 3 Report
My main criticism of this paper belongs in the Introduction section. Potential readers really need to see some references introducing Li-bearing pegmatites in general, then Li-pegmatites in Norway, Finland and Kola, their mineralogical characteristics, and so on.
Basically, in the Intro section you need to demonstrate what exactly made you undertake this work.
Minor comments:
Line 39 - Archean, not "archaic".
Line 40 - crystalline basement, not pedestal.
Line 42 - What is the age of these intrusions. And also, please, enlighten your reader as to what intrusive rocks these are - gabbro, norite, diorite, granodiorite, etc.
Lines 42 and 43 - amphibolite and granulite facies, not phases.
Line 44 - drop "both" as you are listing 3 regions, not 2.
Line 45 - what is the age of mineralized pegmatite?
Line 59 - collected by a single author, in which case he/she should be named, or by multiple/all authors?
Line 62 - what are these "most important rock types"? Please specify.
Line 112 - please replace "acid" with Na-rich.
Line 143 - what exactly are these non-transparent minerals - sulfides, ilmenite, magnetite, other spinels?
Line 150 - what is the age of the Kolmozero-Voronya greenstone belt?
Figure 3 - there is no grey field, just yellow.
Figure 6 - where is lepidolite in microphoto A?
English needs some editing

Reviewer 4 Report
Although the subject of the paper is interesting, as it is focused on a very important contemporary aspect, that is Lithium, the quality of the paper is poor. The English language employed is very poor and requires major revisions, as in many cases the authors' arguments are not clear. Moreover, the terminology employed is also poor. I haven' t finished reviewing the entire manuscript, yet I was forced to stop at some point (page 8) as the manuscript requires major revisions in both language, methodology and discussion.
Please see the attached file for details
