Review by Jupiter

Hi FieldsetJ.

Your page introduce the geology of Sicily with geological history and major units. The structure is clear and simple to follow. Wordings are also simple and easy to understand. Also, it is good to include simplified cross section, evolutionary diagram and simplified geological map to present the geology of an area.

Here are some suggestions:

1. In the beginning, you introduce the geology of Sicily with the collision of the Eurasian plate and the African plate. However in your corresponding diagram, you show a simplified geological map of Sicily with major geological units. First, it may be better to put the simplified geological map to the "Major Tectonic Units" section, as the units are corresponding to your sub-sections. Then, you can include a map showing the boundary between Eurasian plate and the African plate, which is corresponding to your introduction. It will be also easier for the readers to know the location and the collision system of Sicily. For this, you can check the page of Geology_of_India and Geology of Colombia. These two pages use a plate-tectonic map at the beginning to introduce the geology of an area.

2. For the "Major Tectonic Unit" section, it may be better to add an short introduction (What is major tectonic unit? Again, the simplified geological map may be a good diagram to introduce the major tectonic units.) or outline (Any order of units? From the oldest to youngest?) of the section.

3. You have described the stratigraphy of "Hyblean Foreland unit", "The Apenninic-Maghrebian chain" and "Calabrian crystalline basement". It may be better to use 1. 2. 3.... or stratigraphic diagram or point form to clearly show the stratigraphy.

4. It may also be a good idea to show some real picture of the geological unit/features if possible. For example, Geology of Chile have pictures of plateau and mountains.

Generally, I think this page have provided a clear geological history of Sicily. A better arrangement of diagrams, map and real picture will make the page more effective in communication. Jupmira104(talk)

hi J,

1. You can add the small figure showing where is Sicily in the world map or a simple statement for laymen on the introduction like "Sicily is located just off the toe of Italy's boot". When I first read Sicily, I have to find the location by google map. Perhaps, readers like me can get where is Sicily very quickly.

2. The straightigraphy unit of your page is well explained in words. But it would be more clear if you can make a log including the thickness of the unit, any fossil found, symbols of the layer and so on. For example, you can add on under Calabrian crystalline basement and one under Hyblean Foreland unit. You can use the program on internet "SedLog". It's free! I have tried it in Montana. It's good!

3. Some of the explanation is not clear :

• On top are folded Numidian flysch and Sicilidi nappes in the form of a south-verging anticline. What/Where is Numidian flysch and Sicilidi nappes?
• Since late Oligocene, the Sicilian orogenic process started with the accretion of the Calabrian wedge and the deposition of Nummidian flysch in the foreland basins.

On top are folded Numidian flysch and Sicilidi nappes in the form of a south-verging anticline. What is the correct spelling of the bolded word? or they are actually different?

• Based on fossil analyses, the basin has been developing since Late Pliocene, and is suggested to be related to the bending of the carbonate platform due to loading at the front of the Gela nappe. What fossils you are referring to?

You may add blue links or simple statement to explain.

Feedback from dinohk

1. Consider adding some biostratigraphic information such as fossils and paleoenvironment.

2. I agree with Jupiter that some pictures of the actual location would be great.

3. What is the significance of this area? Why are we interested in its geology? Is there something interesting here not found elsewhere? — Preceding unsigned comment added by Dinohk (talk • contribs) 15:08, 23 October 2017 (UTC)

Review by GeoJeremy

Hi FieldsetJ,

Here are my opinions. Hope it helps.

1)I see that you mentioned Mt. Etna. I would be great to give a brief description Mt Etna and how this active geology relates to the ancient geology of Sicily.

2)Maybe a separation of Reference list under a "Reference" topic is good?

3)Since Sicily has an eventful past, I would expect loads of structures found on the island. Would there be enough information to start a new section describing some detail structures?

Feedback from Wlamwk

Hi FieldsetJ:

1. In the summary of the geology of Sicily, I think people who do not have geological background may find the tectonic setting involved difficult to understand as in the first paragraph. It may be better to include a diagram showing the relative positions between the plates, foreland of the thrust system, volcano, etc. The sentences can show more coherence for easier understanding as well.

2. It will be a good idea if you can also include a geological timeline with brief descriptions. So readers can have a clearer idea of the happening order and time interval between the geological events.

3. Miscellaneous items: There are quite a few of typo, especially in the captions for the diagrams, e.g. “reference” and “et al.” in the first diagram and “simplified” in the second. Also, the simplified evolutionary diagram of Sicily is great for illustrating the geological history, however, the quality of it can be improved so that the words on it can be read clearly.

Comments and queries from Graeme Bartlett

• You could write a bit more about Mt Etna, particularly why is there a volcano there now.
• If you split up the Simpified evolutionary diagram into four, it will be easier to read the writing!
• Is there any important or unique minerals described from Sicily? It seems that this would be likely.
• How is Sicily moving / rotating now?
• Are there any important or historic mines there?
• Please add doi's to your references.

• Thanks for adding the mining section. However its needs a reference, and so do some paragraphs in the Hyblean Foreland unit section

• That was quick with the mining ref! Graeme Bartlett (talk) 07:10, 10 November 2017 (UTC)
