Loughshinny is a village in Ireland, about 15 km north of Dublin. This place has a very nice exposure of rocks from the late Car
boniferous. A) What type of deformation are we looking at? B) How was this made? What factors are needed to make this deformation? C) What kind of rocks are these?
Ans A) We are looking at folded (ductile) deformation in the particular scenario. As we know high Temprature and Pressure results in ductile deformation.
B) How was this made? What factors are needed to make this deformation?
Ans. B) This was made by flexural slip folding. Factors need for this deformation are:
Like earth, venus does not have any major faults or folds or rift valleys ridges on its surface thus it does not have any global tectonic or plates of rock in rotation.
Being a terrestrial planet, the seismic data collected from the moment of inertia and possible due to the planet plates are too rigid to move but the phases of volcanoes have been found in the craters in addition mountains, and valleys are commonly found on rocky lands points out to some degree of tectonics present under the planet.
Also, the size and structure of the plan tell about its core, mantle and crustal zones. Also, venus is supported to have a magnetic field not as strong as the earth which is induced by the ionosphere and Solar Winds.
