Definition

Noun: - A type of sedimentary rock formed from the consolidation of sand-sized mineral particles or rock fragments. These rocks are typically bound together by a natural cement, such as silica, calcium carbonate, or iron oxide.

Usage

This term is used in geology to classify and describe rocks with a sandy texture and composition. It specifies the rock's origin (sedimentary) and its primary constituent material (sand).

Examples

• Noun:
  • Sandstone is a common type of arenaceous rock.
  • The cliff face revealed layers of arenaceous rock deposited by ancient rivers.

Advanced Usage

• In geological description: The term is often used in technical reports and academic papers to precisely describe rock strata.
  • The core sample consisted primarily of arenaceous rock, indicating a high-energy depositional environment.

Variants and Related Words

• Arenaceous (adj): Having the properties or composition of sand; sandy.
  • The arenaceous soil was perfect for drainage.
• Psammite (n): A synonym for arenaceous rock, used less commonly.

Synonyms

• Sandstone (Note: While sandstone is a very common type of arenaceous rock, "arenaceous rock" is a broader category that can include other sandy rocks like greywacke or arkose.)
• Psammite
• Sandy rock

Related Terms (Geological Context)

• Argillaceous rock: A sedimentary rock composed primarily of clay-sized particles (e.g., shale).
• Calcareous rock: A sedimentary rock composed primarily of calcium carbonate (e.g., limestone).
• Clastic rock: A broader category of sedimentary rocks formed from fragments of pre-existing rocks, which includes arenaceous rocks.

Noun

1. a sedimentary rock composed of sand
