The paper deals with the review of the results of detection and analysis of fullerenes in natural objects. The fullerenes (generally, buckminsterfullerenes С60) were revealed in hard subsurface rocks and sedimentary deposits of Cretaceous-Paleogene, Perm and Pre-Cambrian stages of the Earth. The map of the Earth regions of fullerene exploration and the data on fullerene composition in the rocks is provided as well. The concepts of both biogenic and abiogenic fullerene origin are known. In the first case, the process of slow metamorphization of putrid mud and terrestrial crop took place under the impact of compressing and temperature, as a result of which various allotrope compounds of hydrocarbon dispersed in the mineral matrix were formed and accumulated. In the second case, the formation of fullerenes took place due to the shocking impact during thunderbolt or fireballs (Sudbury meteorite, carbonic chondritic meteorites) strikes on the rocks of earth surface, as well as global forest fires. For reliable fullerene identification in the samples of sedimentary and subsurface rocks should be used only physical-chemical methods of high definitions, such as laser desorption / ionization and electric-shocking mass-spectrometry. In the natural objects is predominantly revealed fullerene С60.Other types of fullerenes - C70, C74, C78, C84 and C100 are identified more rarely. A hypothesis on the composition of carbonic nanostructures in the rocks of mud volcanoes in the aspect of obtained information is developed.

The paper reviews the publications on the search and exploration of carbonic nanotubes and other nanocarbonic structures in subsurface rocks. It is shown that the graphenes and carbonic nanotubes (CNT) exist in the composition of various magmatic and sedimentary rocks. They are formed in the graphite globules of volcanic rocks, as well as in the sediments, where the pressure, the particles of metallic catalysts, the tension stresses and time factors in million years compensate the absence of high temperatures. Experimental laboratory modeling of natural processes has been carried out and the reality of formation of carbonic nanostructures during the pyrolysis of volcanic gases on the lava catalysts, mechanical activation and processing of amorphous carbon or bituminous coal shown. Principal possibility of realization of technology of CNT mass production via pyrolysis of hydrocarbon crude material in the presence of different catalytically-active natural minerals has been reviewed and proven. The analysis of the aspects following the activity of mud volcanoes shows that there are all suppositions for the formation of carbonic nanostructures: the pressure bump of deep rocks out of the hot eruptive centre, methane as carbonic crude, catalytically-active breccias containing transition metals and their oxides, the process of methane burning in the medium poor of oxygen. However, it is not yet absolutely clear. As a working hypothesis we propose a model of formation of these structures due to the mud volcanism activity in the reactions of methane flow, the catalysts in which natural minerals exist. In such processes as a result of intensive methane flow, there occur negative pressure values and cavitation effects in the presence of which local temperature and pressure increase efficient for formation of adamantine and nanosize carbonic structures take place. In case if this mechanism is real, the studies point to a perspective of obtaining valuable products in conditions of natural geological processes. There are no messages or publications yet on the exploration of carbonic nanostructures in the rocks of mud volcanoes.
