Clastic

Part of Speech

Adjective

Pronunciation

/ˈklæstɪk/

Definitions

• Relating to or composed of fragments of rocks, minerals, or other materials that have been broken down and reassembled, especially in the context of geology.
• Characterized by the presence of clasts (broken pieces) within a rock or sediment.
• In some contexts, refers to the process of fragmentation or the materials involved in this process.

Usage Examples

• "The clastic nature of the rock indicated it had undergone significant weathering and erosion."
• "Clastic sediments can be found in many geological formations, often indicating the presence of a past environmental change."
• "The geologists studied the clastic layers to understand the historical climate shifts in the region."

Etymology

Derived from the Greek word "klastos," meaning "broken," combined with the suffix "-ic," indicating a characteristic or relation to the concept of being broken or fragmented. The term "clastic" has been used since the late 19th century in geology to describe rocks and materials formed by the process of fragmentation.

Synonyms

• Fragmented
• Broken
• Disaggregated
• Shattered
• Crushed
• Detrital

Antonyms

• Unbroken
• Intact
• Solid
• Continuous

Translations

Regional Pronunciation Variations

While the pronunciation of "clastic" tends to be standard across most English-speaking regions, there may be slight variations in the emphasis on the first or second syllables, especially in different accents or regional speech patterns.

Historical Usage

The term "clastic" originated in the late 19th century as geologists began categorizing and describing different types of rocks and sediments. The word's use has remained consistent, particularly in the fields of geology and sedimentology, to describe materials or rocks that have been broken down and reassembled through natural processes.

Cultural Nuances

While "clastic" is primarily used in scientific contexts, particularly in geology, it may also appear in discussions about environmental change and the natural world. In everyday usage, it is not commonly used outside of these technical fields, and its understanding is typically limited to those familiar with earth sciences.

More Information

Clastic materials are critical to understanding the Earth's geological history. These fragments, or "clasts," provide valuable insights into past environmental conditions, climate change, and the processes of erosion and deposition that shape the planet. Clastic rocks are often categorized based on the size of their particles, ranging from fine-grained siltstone to coarse-grained conglomerates.
