Final answer:
False. A matrix is a common constituent of conglomerates and breccias in geology. It refers to the material that surrounds and binds together the clasts or fragments within the rock. The matrix can be composed of various substances, such as fine-grained minerals, cement, or even organic material.
Step-by-step explanation:
A matrix is a common constituent of conglomerates and breccias in geology. It refers to the material that surrounds and binds together the clasts or fragments within the rock. The matrix can be composed of various substances, such as fine-grained minerals, cement, or even organic material. Matrix, in the context of sedimentary rocks like conglomerates and breccias, refers to the material that fills the spaces between the clasts (rock fragments) or particles. While conglomerates and breccias both contain clasts, they differ in the size and nature of these clasts.
Contain angular clasts, and the matrix is typically finer-grained material, similar to that in conglomerates. Contain rounded clasts, and the matrix is often finer-grained material, such as sand or mud, that surrounds and binds the larger, rounded clasts. So, matrix is indeed a common constituent in both conglomerates and breccias, but it's important to note that conglomerates have rounded clasts, while breccias have angular clasts.
