Dear Dr. Lucci,

Thank you very much for your response to the reviewers. I am satisfied that you have addressed their comments and suggestions to a sufficient level, but I have a few requests for improvement before the paper is published:

The first relates to the analytical totals for the EPMA data, which was raised (for oxides) by Reviewer 2, and appears to be a general issue for all phases. The totals for anhydrous phases are generally below 100%, and regularly below 98%. There needs to be a way for the reader to verify data precision and accuracy, but the analytical techniques section on EPMA analyses does not mention methods or results of standard analysis, nor precision and accuracy. Given the importance of mineral chemistry for the thermobaromety, and the generally low totals, I think this should be discussed. I would recommend adding a table summarising the repeat analyses of the external mineral standards used to Appendix A.

Second, in Table S1: please correct ‘Fedspar’

Finally, regarding Table 1: Given that all of the mineral compositional data are in supplementary tables, I wonder whether the whole-rock geochemical data may be better off in a supplementary table as well. That way, any reader can easily download the Excel sheet for both liquids and crystals and so reproduce the thermobarometric calculations.

Best regards,

Johan Lissenberg

Topical Editor

Dear authors,

Thank for submitting your ms for evaluation with Solid Earth. The Executive Editor has now looked at your ms, and has come to the following conclusion:

The topical editor has come to the decision to recommend publication pending a couple of technical corrections. While I endorse these recommendations, I do not consider the paper publishable in its current form.
Looking at the ms in its entirety, I conclude that a final careful revision of the English must be conducted. There are numerous elements in the text where the writing can be much clearer, less ambiguous and grammatically correct. As an example I please look at Conclusion #4. The current wording makes no sense, is impossible to understand and grammatically incorrect.
The uptake of the published paper by your peers will be improved by a well-written narrative. I therefore expect to see a revised version of the manuscript including the technical comments and revision of the English before I make my final decision on the ms.

On the basis of this recommendation, I return the ms to you. Please revise the paper according to the recommendations above. I'm looking forward to receiving the revised version.

Best regards,

Johan Lissenberg

Dear Dr. Lucci,

Many thanks for your revisions. I am satisfied that you have addressed the QA/QC for the electron microprobe data, and that the general level of writing has improved. There remain, however, a number of grammatical issues: these include (but are probably not limited to) the following:

89: ‘reconstruting’
200-202: ‘That makes it important, for a better comprehension and exploitation of the geothermal resource, a revised assessment of the structure of the magmatic plumbing system beneath LHVC.’ Grammatically incorrect.
270: ‘It is worth notice that’
303: ‘To note it is the absence of olivine’
310: ‘It is also reported the presence of’
311-12: ‘patchy rounded zone corners cores’
363: ‘in studied samples’
414-5: ‘normal monotonous zoning outer rims’
502-3: ‘However, crucial for mineral-liquid thermo-barometric modeling, it is the use of phenocrysts with strongly zoned textures’
528 and later: ‘Rhodes’s diagram’
594: ‘Pressure ranges 3.1-11.5 kbar’
641-2: ‘since the invariably lower pressure values obtained by Opx-liquid barometer’
690: ‘SiO2’
685: ‘This allow us’
890: ‘A second magma transport and storage systems’
1073-4: ‘where basalts rapidly ascend and stall prior to erupt‘

Prior to recommending acceptance of the manuscript, I would like to request that these, along with any other remaining grammar and spelling issues, be fixed.

Best regards,

Johan Lissenberg
