Related Terms

Rafted plate, fractured plates.

Subtypes by Origin

  1. (1)

    Ice plates. Ice plates suspended in water can be found in frazil ice. An ice floe is any relatively flat, isolated piece of sea ice 20 m or more across; it is called ice cake if it is less than 20 m across. Circular pieces of ice whose rim is raised due to the pieces striking against one another are called pancake ice (Sechrist et al. 1989).

     
  2. (2)

    Lava plates (2.1). Cooling of the surface of lava lakes produces a solid crust and develops fractures in it. The surface of a lava lake can either display a mosaic composed of several cold plates separated by incandescent zones or be quasi-solidified with a few small permanent openings that let the gas escape (Bouche et al. 2010). (2.2) Platy-ridged morphology is observed on the surface of large flood basalts, formed as...
