Typically, geological mineral veins were created by glacial movement. As the glaciers cut through the surface of the land, they deposited the minerals that are found beneath the surface today. Answer by FutureLPGAgolfer Cooling Lava, cooling magma, and evaporation.

∙ 12y agoHigh pressure high temperature fluids can cause fracturing of rock masses. However the loss of confining pressure when the fracturing occurs causes the fluid to flash boil. This causes the minerals that are dissolved in the fluid to rapidly exsolve and crystallise in the cracks in the rock, forming mineral veins.
Further to this, cooling hydrothermal fluids that pass through preexisting fractures can also deposit minerals causing mineral veins to form.

Were mineral veins once in solutions?
yea
What is another word for mineral veins?
imperative mining
What are large mineral crytals commonly found in?
Geodes, mineral veins and layered igneous intrusions.
How do veins form?
pure metals that crystallize from hot water solutions underground often form veins.Veins form when rock collides with another rock and the rock that collide pushes the other rock untill only a little bit of it is left
Minerals deposits left behind that fill in the open spaces created by weakness and rock formation called?
Veins generally. In mining: veins, lodes or ore-bodies. They are normally precipitates of metallic compounds.
What happens when blood pools in the veins?
Varicose veins form when blood pools in the veins.
What mineral occurs in veins?
Copper, gold, silver, to name only three.
How do you determine a mineral’s streak?
The color of a mineral in powdered form is called the mineral's Streak
Lead's ore body?
Primarily the mineral galena. Sulfide rich ore veins.
How does Beryl form?
Beryl is exclusively of a pegmatite mineral. When this pegmatite magma has a rich source of beryllium, the beryl crystals are formed. They are formed in high temperature veins by these beryllium bearing gas content.
Where can zinc be found in rocks?
It is found in veins in rocks (where it was deposited hydro-thermally) as the mineral sphalerite.
What are mineral deposits beneath earths surface that are different from the surrounding rocks are called what?
These are called veins
