    Breccia, lithified sedimentary rock consisting of angular or subangular fragments larger than 2 millimetres ( inch). It differs from a conglomerate, which consists of rounded clasts. A brief treatment of breccias follows. For full treatment, see sedimentary rock: Conglomerates and breccias.

Breccias and coarse fragmentites. Amsterdam ; New York: Elsevier, (OCoLC)   The subject of breccias and mineralisation is rather large and it is not possible to remotely cover the field in one slender volume.

As a starting point it is perhaps best to deal with the vexing problem of breccia definition. Readers may be surprised to hear that there is no satisfactory definition of the : Roger Taylor.

Conclusions In the present contribution, breccias, some other coarse fragmentites and related ores have been organized and reviewed with the emphasis on objective (empirical, observational) prop- erties.

The attributes discussed here are consid- ered sufficient for a reasonably detailed docu- mentation of a breccia field by: Breccias and Fragmentites carried out by Laznicka (),h e attempted to categorize all the coarse fragmental rocks ac- cording to their associations with metallic ore accumulations.

The Beaverhead meteorite impact was first recognized in (Hargraves et al., ), when shatter cones were found in Prot– erozoic rocks in the Beaverhead Mountains, near Medicine Lodge Creek in southwest Montana (Fig.

The rock-flour type matrix has a variable participation, but it has obviously a minor participation (less than 50%, Sillitoe, ) as compared to the clasts.
