Question

Hot fluids that come in contact with solid rock result in what

Answer 1

When hot fluids come in contact with solid rock, it can result in metamorphism or melting into magma. These processes are important in the formation of rocks and geological features.

Step-by-step explanation:

When hot fluids come in contact with solid rock, it can result in several processes, depending on the temperature and pressure conditions. One possibility is that the rock may undergo metamorphism, where minerals and textures are transformed due to heat and pressure. Another possibility is that the rock may melt and turn into magma, which can eventually solidify and form igneous rock. In some cases, the hot fluids may generate steam or vaporize the water that comes into contact with the rock. These processes play a significant role in the formation of different types of rocks and geological features.

Answer 2

This depends on the fluid; If it is water based it can change in mineral composition without having to melt.

If the fluid is a magma high-temperature fluid this can melt the rock and/or bake the rock, which causes a contact aureole to form on the outer rock walls. this metamorphoses the rock wall.
The size of the aureole depends on the heat of the intrusion, its size, and the temperature difference with the wall rocks.
