How Is Gold Formed Origins And Process Thoughtco

may 06, 2019 As the earth formed, heavy elements such as iron and gold sank toward the planets core. If no other event had occurred, there would be no gold in the earths crust. but, around billion years ago, earth was bombarded by asteroid impacts. these impacts stirred the deeper layers of the planet and forced some gold into the mantle and crust.

there are three types of rocks: igneous, sedimentary and metamorphic. each of these types is part of the rock cycle. through changes in conditions one rock type can become another rock type. Or it can become a different rock of the same type. what are rocks? rock is a naturally formed, non-living earth material.

What Are Metamorphic Rocks Usgs

metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
