When the rock was forming other minerals that were near the forming place of the metamorphic rock were mixed in after the pressure has been made on the metamorphic rock. I am a seventh grade teacher so I know the answer. We are going over this in class right now.

Why are minerals mined only in those regions where they occur in the of ores?
Minerals are mined only in region where they form in ores as the cost of extraction is very high.
What do most igneous sedimentary and metamorphic rock have in common?
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.

Explain why weathering can only occur on the surface of the earth?
Weathering can only occur on the surface of the earth because the weather is only present on the surface of the earth. The surface of the earth refers to any exposed area.
Metamorphic rocks composed of only one mineral that forms equidimensional crystals have what texture?
They have a non-foliated texture, without banding, non-gneissic; characteristic of marble and quartzite.
Why Some Minerals Only Occur In Metamorphic Rocks.?
because if the metamorphic rocks are big they will shrink
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
Why do some minerals only occur in metamorphic rocks?
As the degree of hydration decreases in a rock undergoing metamorphosis, certain minerals cannot exist. New minerals then form that do not require water for their formation. This environment of heat, pressure, and lack of water is necessary for the formation of certain minerals.
Do metamorphic rocks have different kinds of minerals from their parent rocks?
Of course they can. The overall compositions of the rocks will remain the same (assuming a closed system, which isn't always the case), but mineralogically there will be changes due to metamorphic pressures and temperatures. There are a whole list of minerals which only formed from metamorphic processes.
Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
Why are minerals mined only in those regions where they occur in the of ores?
Minerals are mined only in region where they form in ores as the cost of extraction is very high.
Is coal on the Mohs scale of hardness?
No. The Mohs scale only lists minerals. Coal is a sedimentary or metamorphic rock, depending on the variety.

What do Metamorphic and Sedimentary rocks have in common?
