Gold is not "formed" in rock so much as it will tend to concentrate under certain geologic conditions. We see evidence of gold grains in some rivers, and nuggets in some rock formations. There are also veins of gold that are frequently associated with quartz in some rock strata. This native gold has a good amount of silver in with it. There are massive quantities of gold floating around in sea water, but on the atomic level, and, as such, are not recoverable. Remember that gold is an element, and it isn't "made" or "formed" in nature so much as it is a part of the "mix" of the things that make up the earth's structure. A link can be found below to the Wikipedia post on gold. Check it out and pay particular attention to the section on Occurance.
They are found in sedimentary rocks mostly in sediment deposits.
The rock that is formed is an igneous rock. It's formed when the magma aka lava cools down it turns into a rock which is an igneous rock.
Sedimentary rock can be formed from lithified sediments.
The rock that formed from lava would have smaller crystals than the rock that formed from magma.
The rock formed by cooling a liquid rock after processing is called a crystal.
Slate is formed out of a sedimentary rock called Shale. It is a foliated metamorphic rock.
hard strong rocks
Rock was formed when the earth was made.
The rock formed from molten rock is IGNEOUS
The rock that is formed is an igneous rock. It's formed when the magma aka lava cools down it turns into a rock which is an igneous rock.
Igneous rock is formed.
Igneous rock is formed when magma cools and becomes solid.
Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.
Igneous rock is the name for the types of rock formed when melted rock hardens.
All rock types can be formed from any other rock type.
Metamorphic rocks are formed when heat and presser shape an old rock into a new rock
Sedimentary rock can be formed from lithified sediments.
Yes! That's precisely how igneous rock is formed
