Shale is a sedimentaory rock, while Slate is a metamorphic rock. Generally the shale is metamorphosed into slate.
The Shale is not a metamorphic rock it is a sedimentary rock.
A metamorphic rock.
shale or mudstone
Many kinds of rocks both of igneous and sedimentary nature eg; Limestone (sedimentary ) to marble or granite or diorite (igneous) to gneiss.
Shale is a sedimentary rock that can be metamorphosed into slate by "increased pressure" and heating.
metamorphosed shale
Shale is a sedimentaory rock, while Slate is a metamorphic rock. Generally the shale is metamorphosed into slate.
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
The Shale is not a metamorphic rock it is a sedimentary rock.
it becomes a shale rock. There is no way that chalk, a form of limestone, can be metamorphosed into shale. It will like limestone change to marble.
The application of pressure / heat.
A metamorphic rock.
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
shale or mudstone
Phyllite is metamorphosed slate, which is also a metamorphic rock. Shale or mudstone is the protolith (parent rock) of slate.
If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.
