Analysis of Apollo 14 samples suggests that there are five major geologic constituents present in the immediate landing area: regolith breccias, fragmental breccias, igneous lithologies, granulitic lithologies, and impact-melt lithologies.
KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (Rare Earth Elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks.
Mélange, a geological breccia above a subduction zone environment
The first Novato meteorite, a L6 type chondrite fragmental breccia, was found by Novato resident Lisa Webber following Jenniskens' publication of the trajectory of the fireball from video recorded by stations of his Cameras for Allsky Meteor Surveillance project.
In 1997, a near complete skeleton of a second species of Australopithecus (StW 573) was found in the caves by Ronald J. Clarke; extraction of the remains from the surrounding breccia is ongoing.
Suevite is a rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
These type of breccia usually are of marine origin and are formed by near-bottom turbidity currents.
