Oil components and heavy metals in blowouts of Golubitsky mud volcano
The article presents the results of blowouts analysis of Golubitsky volcano island that were erupted during October 15-27, 2015. Hydrocarbons concentration in the studied erupted samples were nearly 0,49…1,48 g/kg, resinous substances - 0,16…0,47 g/kg dry weight. Molecular composition of paraffin hydrocarbons is characterized by monotonous distribution of homologs from C17 up to C31, their chromatograms had two «humps» of undivided naphten-aromatic components with maximums at C21 and C29. In the average, mass fractions of the identified polyaromatic hydrocarbons (PAH) decrease in the rank: fluorantene > naphthalene > 2-methylnaphthalene > triphynilene > phenantrene > chrysene > benzo(b)phluorantene > benzo(g,h,i)perylene > benzo(k)phluorantene > benzo(a)pyrene > dibenzo(a,h)antracene. Low molecular PAH of mainly oil origin more than 10 times exceeded the number of high molecular PAH of pyro-genic genesis. In the studied samples of the mud-volcano breccia, concentration of aluminum, iron, manganese, nickel, copper and mercury can be compared with the concentration of these metals in the Earth’s crust, concentration of vanadium, zinc, chromium, lead, arsenic and cadmium is higher in the blowouts, while that of barium and strontium is lower than in the earth’s crust.
