The unusual mineralogical composition of the accessory minerals of the salse breccia of mud volcanoes in Azerbaijan, in particular the presence of self-originated minerals (gold, gold copper, iron, nickel, chromium, silver, and tin), many unusual sulphides, oxides and others were considered in the article. In addition to, the isolation of unusual forms of many minerals, including self-originated iron, wustite, hematite is mentioned. They form hollow, small blobs, some other elements – copper, lead, zinc, hematite, melted purified fragments of salse breccia of separate small druses, natural lime and other in the composition of breccia. All these facts are considered as signs of the effect of deep fluids on the salse breccia of mud volcanoes.
