Question

which type of metal is found in sedimentary and igneous rocks​

Answer 1

Answer:

Explanation:

There are two ways metals find their way into rocks; the first is when the metal is a native component of the minerals of the rock from the beginning; the second is when metals are introduced into rocks after they have formed.

Some types of rocks commonly include some metallic elements naturally. For instance, platinum and palladium, nickel, iron, silver, copper,lead, zinc and other metals are common in many igneous rocks naturally, especially the mafic (iron-magnesium rich) igneous rocks. Valuable elements frequently found in sedimentary rocks are durable and easily transported materials, like zircon or in some places, gold.

Other metals are carried by hydrothermal fluids through rocks, and these deposit metals into rocks which originally didn’t contain them. Common hydrothermally deposited metals include gold, silver, copper, lead, zinc and many others.

Since hydrothermal fluids move through all sorts of rocks, hydrothermally deposited metals can occur in any sort of rock, although some types of rocks are more reactive to the fluids and more likely to contain those elements brought by the fluids.

I hope that helps.
