ES LT 3 reviewer

This term describes a natural material that contains both valuable and waste materials.

These are narrow pathways in hydrothermal deposits where ores could be found.

• Veins

• Disseminated

• Residual

• Evaporites

This process forms different minerals that settle as different layers, as a magma chamber gradually cools.

This layer of the Earth moves as magma rises to the surface, resulting to the large scale features of the planet and ore deposits.

• Asthenosphere

• Inner Core

• Lithosphere

• Outer Core

This term describes salts that are left behind by a dried up lake or river.

• Precipitates

• Evaporites

• Laterites

• Veins

This is the term used for heavy sedimentary materials that are not sifted by ocean waves and concentrate on areas in the ocean bed.

• Placer deposits

• Clastic deposits

• Laterite deposit

• Magmatic ore deposit

These are the unaltered rocks that when chemically weathered produced enriched soil known as residual ore deposits

These refer to energy resources in the form of gas from the pressurized hydrocarbons during burial

This period in the Earth’s history about 300-400 million years ago is when fossil fuels were formed due to ideal conditions.
