1. Plural of eclogite; a dense, granular metamorphic rock composed primarily of garnet and pyroxene, formed under high pressure and temperature conditions deep within the Earth.
Usage: geology; technical term; typically used in academic and professional geological contexts

Examples

• Eclogites are found in subduction zones where oceanic crust has been pushed deep into the mantle.
• The study of eclogites helps geologists understand the conditions of the Earth's interior.
• These eclogites contain minerals that only form under extreme pressure.
• Geologists discovered eclogites in the mountain range, indicating ancient tectonic activity.
• The composition of eclogites reveals information about the depth at which they formed.
