Breccia & Conglomerate Stone

Breccia is a sedimentary rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix.

​​

Conglomerate is a type of sedimentary rock that is composed primarily of rounded or water-worn pebbles, cobbles, and boulders, which are known as clasts. These clasts are typically cemented together by a matrix of finer-grained sedimentary material, such as sand, silt, or clay.

Colors They Come In - Breccia & Conglomerate can be any color.

​​

Fracture - Fracture networks, Subsurface expanding vapor explosions, Attritional wear, Stress heterogeneities, Rock properties

 

Shape - Angular or Subangular fragments that are larger than 2 millimeters in size

​

Luster - Dull

​

Texture - Fine Grained, Smooth, Bumpy, Waxy

​

Streak - White or Light-colored

​

Locality - Anywhere a high-energy environment is possible

​

Where Breccia Can Be Found - Near fault zones, Near landslide and mudslide zones, Near volcanic activity, Near meteorite impact craters, Near coral reefs, Underground along faults or where caves collapse

​

Where Conglomerate Can Be Found - Death Valley National Park in the United States, Cliffs along the east coast of Scotland, Dome-shaped hills of Kata, Tjuta in Australia, Underlying anthracite of the coal fields of Pennsylvania, Base of the Sangre de Cristo mountains of Colorado

Hardness On The Mohs Scale - 3 To 6.5 Out Of 10
