Iberian tectonic plate geology and palaeography

Iberian tectonic plate geology and palaeography

Iberian tectonic plate geology and palaeography is a subject not most people know about, even though they might be geologists themselves, because it is a subdivision very local and specific into the vast field of study being the object for geology.

Here you are an excellent summary about how vast geology is. It is in Spanish, but there are some diagrams in English, and the types of rocks do not differ very much from their names in English (though you should check their chemical formula because I have found many cases in which names seem alike and their real meaning differs. e. g. tin(1) (pure Sn metal in English, whereas it is Zn/Cu alloy in Spanish, with no Sn at all).

(1) It is translated as: “latón” in Spanish, which is the Zn/Cu alloy.

In this other address you have a graphical explanation of some basic concepts for plate tectonics.


There are various sources for geological maps you can find that give information on how Iberian plate was pushed and tilted giving birth to Duero, Ebro, Tajo, Guadalquivir, and the main stresses, geological periods and formations.

There are also various sources of information in order to find similar data about the Atlas Massif and Rif Ridge in North-West Africa.

I personally will give you another more than trustworthy source of information. It combines three agents for its development, being the first one terrestrial gravity, the second one water natural paths, and the third roads and railways development.

You can check in databases the current situation regarding flashfloods, earthquakes, volcanic eruptions, droughts following this roadmaps path, and bear in mind there is another microplate in Arabian peninsula.

Altering the path and salinity concentrations in so enormous proportions gives this as a result: global problem.

So it seems to me that enhancing productivity produces as a side effect, an enormous unbalance with very serious consequences. For instance, enhancing geothermal energy in order to lower cost and make it more profitable produces a thermal unbalance which increases the difference between minimum and maximum temperature in the bedrock of aquifers thus breaking the rocks and drying the substrates.

If it were done in many micropowerplants generators (eliminating leakage due to electricity transport, which is a reality you can check by watching the thermal specifications for any high voltage cables), a lot of HEAT would not be ‘lost’ into the surrounding vicinities being these, insulators (wich make the processes slower, but end up releasing their energies), or simply the open air.

The thermal increase in max min temperatures provokes fractures due to the increased difference, and the more large and/or quick this temperature change is, the more easily the bedrock, rock or material will break.

Next time you order a drink in a bar and hear a cracking sound (if the music is not too loud) when liquid is poured into the glass with ice cubes, just think that the technical name for that phenomenon, is called thermal shock. If the difference in temperature is bigger and or the velocity with which the liquid is poured is quicker the crackling sound and cracks in the cubes will be louder and greater respectively.

The same works for cooling, being not cool at all!

I am a teacher of English who started to write this blog in May 2014. In the column on the right I included some useful links and widgets Italian is another section of my blog which I called 'Cornice Italiana'. There are various tags and categories you can pick from. I also paint, compose, and play music, I always liked science, nature, arts, language... and other subjects which you can come across while reading my posts. Best regards.
