What is a vein deposit?

• A deposit formed when minerals precipitate out of fluids and form veins within the rock

• A deposit where minerals fill up cavities in host rocks

• A sedimentary layer containing high mineral content

What role does the boiling of fluids play in the formation of hydrothermal mineral deposits?

• It purifies the fluid by removing unwanted elements

• It leads to rapid cooling and deposition of minerals

• It causes the fluid to evaporate completely, leaving minerals behind

• It increases the fluid's mineral capacity
