Chapter 5: Problem 6

What ultimately happens to most of the clay that forms during the hydrolysis of silicate minerals?

Short Answer

Expert verified

Most of the clay formed during the hydrolysis of silicate minerals is transported by water and wind, and eventually gets deposited in various environments such as riverbanks, lakes, or ocean floors. Over time, the deposited clay undergoes compaction, burial, and diagenesis, transforming it into sedimentary rocks like mudstone, shale, or claystone. These sedimentary rocks can later be uplifted, eroded, and subjected to hydrolysis again, continuing the cycle of rock transformation.

Step by step solution

Understand the hydrolysis of silicate minerals and clay formation

Hydrolysis is a chemical reaction in which water reacts with a mineral, breaking its chemical bonds and forming new minerals. In the case of silicate minerals, hydrolysis mostly involves the breaking of Si-O and Al-O bonds by the interaction of water. When silicate minerals react with water, they decompose, and clay minerals are one of the common products formed.

Recognize the types of clay formed during the hydrolysis

During the hydrolysis of silicate minerals, different types of clay minerals can be formed, such as Kaolinite, Illite, and Montmorillonite, among others. These clay minerals have different properties and are typically formed depending on the environmental conditions and the precursor minerals.

Identify the processes that affect clay after its formation

Once clay minerals are formed, they can be subjected to different processes such as transportation, deposition, compaction, and diagenesis. The clay minerals can be transported by water, wind, or other agents and deposited in different environments, such as riverbanks, lakes, or ocean floors. They can also be compacted under pressure and undergo diagenesis, which is the process of transformation into sedimentary rocks.

Determine what ultimately happens to most of the clay formed from silicate mineral hydrolysis

Most of the clay that forms during the hydrolysis of silicate minerals gets transported by water and wind and eventually gets deposited in various environments. Over time, the deposited clay can be compacted, buried, and subjected to diagenesis, transforming it into sedimentary rocks such as mudstone, shale, or claystone. These sedimentary rocks can then be uplifted, eroded, and subjected to hydrolysis again, continuing the cycle of rock transformation.
