a region has a geothermal gradient of 180 ˚C km^-1.what type of metamorphism will occur at a pressure of 1.2×10^8 pa? answer the question by completing the sentence below.
In these condition there would be ........??? metamorphism.
I would appreciate if someone could answer this question.thanks
To determine the type of metamorphism that would occur at a given pressure, we can use the concept of metamorphic facies and pressure-temperature (P-T) diagrams. Metamorphic facies are defined sets of mineral assemblages that form under specific pressure and temperature conditions.
In this case, we have the pressure value of 1.2×10^8 Pa. However, to accurately determine the metamorphic facies, we also need information about the temperature or the P-T conditions. The given information only mentions the geothermal gradient of the region, which represents the rate at which temperature increases with depth. It does not provide specific temperature values.
To fully answer your question and determine the type of metamorphism, we would need additional information about the temperature conditions or access to a P-T diagram for the region in question.
