Summary
[edit]DescriptionPlumose marking on joint surface in limestone (Columbus Limestone, Middle Devonian; Seneca Caverns, Ohio, USA).jpg |
English: Joints are fractures in rocks along which no differential displacement has occurred. This distinguishes them from faults, along which displacement has taken place.
Some joint surfaces have feathery-like features called plumose markings. They consist of an axis and small-scale, radiating-outward ridges. The divergent-direction axis points toward the direction of fracture propagation. Host rock: Columbus Limestone, Middle Devonian Locality: trailside, Level 3 of Seneca Caverns, just south of Flat Rock Quarry & south-southwest of the town of Bellevue, northern Ohio, USA |
