(1) Breccias are composite rocks formed from all other rock types through crushing, mixing and being smashed by meteorite impacts.

(2) More attention should be paid to breccia Au deposits.

(3) The host rock is a tectonic breccia, the proximal enclosing rock is C phyllite.

(4) The ore-bearing rock are mainly fine elastic rocks, breccia of albite-carbonate and carbonaceous- siliceous argillaceous rock.

(5) Crypto-explosive breccia structures were well developed. The diameter of prisms is in proportion to the size of micro-fabric phenocryst .

(6) Gold - hosted breccia in Shuangwang ore deposit is hydrofracturing breccia.

(7) The hydrofracturing breccia is formed by deep rich- sodic and gold-hosted fluid hydrofracturing in a set of Devonian system hot-water sedimentary rich- sodic rocks.

(8) They are mainly limburgite and breccia like limburgite and intruded the Cretaceous red basins.

(9) The diatreme breccia pipes belong to volcanic crater phase and volcanic conduit phase(sentencedict.com/breccia.html), and consist of breccias and binding material.

(10) The process of explosion condensation mineralization concealed explosion breccia mass is expounded.

(11) Cryptoexplosive breccia was discovered by the author in large Naming granitic batholith for the first time in 1987, which is described in this paper.

(12) Fault rocks with a random fabric include fault breccia, fault gouge, pseudotachylyte and cataclastic rocks.

(13) Pyrites in Dianfang gold deposit of Proterozoic explosive breccia type are mainly gold - bearing minerals.

(14) The Westbury sediments are middle Pleistocene in age with numerous small mammal faunas in different parts of the breccia sequences.

(15) Gold bodys are metasomatic vains, and was generated by diorite and surrounding rock which suffered multi-stage breccia, silicification and sericite hydrothermal alteration.

(16) This investigation also finds that different lithology have different physical properties and the slaggy basalt, the amygdaline basalt and the volcanic breccia have the best physical properties.

(17) Favorable structure for metallization is the contact-zone as well . as explosive breccia.

(18) Late period of deformation is characterized by cataclasis and breakage forming varied sorts of brittle fractures and breccia zones.

(19) The extrusive rock unit includes basalt, andesite, boninite and albitite as well as breccia and tuff.

(20) As with Dhofar 287 , the stone appears to be a portion of a regolith breccia that contains a large clast of cumulate olivine gabbro and many small clasts.

(21) Xiangluwanzi gold deposit is a volcanogenic hydrothermal ore deposit related to volcanic cryptoexplosive breccia body.

(22) Jurassic volcanic rocks in Yingshan fault depression are mainly andesite, basalt, dacite , volcanic breccia and tuff.

(23) The type of veinlet like and dissemination like uranium mineralization mainly is fracture and breccia type.

(24) The Shuangwang gold-bearing albitite zone, which is composed of stratabound albitite , albitite breccia occurred conformably in the Xinghongpu Group, Devonian silt-slate.

(25) The thrid part are tuff, ferruginous dolomite, crystal tuff and volcanic breccia.

(26) In the extreme case the boxwork collapses, forming a breccia.
