What metamorphic rock does siltstone turn into?

OpenStudy (anonymous):

a bug duh

OpenStudy (anonymous):

May you please say that more specific? Im pretty sure siltstone is a rock

OpenStudy (anonymous):

ok one momment plz

Heat and pressure cause minerals in the rock to re-crystallize, re-orient and sometimes interact with each other causing the rock to metamorphose. There are two types of metamorphism: Contact metamorphism and regional metamorphism. Contact metamorphism is when an igneous intrusion moves into a rock formation and literally bakes it. The heat causes the minerals in the rock to recrystallize and re-orient themselves. Regional metamorphism is when rock is buried beneath miles of rock and the rock is subjected to massive amounts of heat and pressure and the rock twists, recrystallizes and re-orients itself into a new metamorphic rock. It takes millions of years for rock to be slowly buried and subject to pressure. Contact metamorphism happens relatively quickly

Well that was not right

OpenStudy (anonymous):

I asked what it turns into

OpenStudy (anonymous):

When siltstone encounters high pressure such as heat, they can metamorphose into different varieties of rock, namely schist and gneiss. These metamorphic rocks are notable for their streaks of crystallized minerals. Once siltstone has been altered in this manner, it loses all of its original structure.

It turns into schist
