- Аннотация: The acid residual contains micro-crystals and nano-particles represented by silicates, phosphates, sulphates, chlorides, sulphides, oxides, native metals, intermetallics, and possibly carbides. A lot of native nickel, iron and copper, sometimes zinc, bismuth, silver, tin, manganese, aluminum, tungsten and platinum particles are found in the insoluble acid residual of heraclites. Native nickel, iron and copper have a form of elongated lamellae or aggregated flakes of craggy form. Nanoparticles of Ni, Fe and Cu separately overfill with spots the clasts of carbonaceous matrix. The findings of intermetallics in the probes of heraclites excite a particular interest, namely copper and zinc (native brass); titanium and iron, iron and chromium, zinc and aluminum, zinc and iron, nickel and copper. ICP-MS analyses of heraclites samples have evidenced that ones are characterized by anomalous geochemical association of chalco-, sidero-, litho-phillic and rare earth elements. Besides, there are noticed an increased concentration of lanthanides in heraclites: Ce, La, Nd, Pr, Gd, and Dy. The study of mineral composition of the trace elements in heraclites and results of the ICP-MS made by carbon dioxide, nitrogen, methane, ethane, propane, as well as hydrothermal solution with heavier hydrocarbons. The heavier hydrocarbons or likely metal-organic compounds have played the role of carriers for the metals and intermetallics. Deep of paleo-fluids were involved into complex biochemical process by prokaryotes that resulted in formation of organic matter and carbonates of the Miocene biostromes and buildups.
