Interstitial fibrous-matted micron-scale aggregates of few-layered graphene nano-flakes, multi-layered carbon nanotubes, fullerenes, and fullerenoids have been found between quartz and potassium feldspar grains of slag-like high temperature and shock-metamorphosed rocks (polymictous sandstones) of the Dzharakuduk area (Kyzyl-Kum Desert, Uzbekistan). This is the first finding of few-layered graphene nano-flakes as well as multi-layered carbon nanotubes (with ~10 Å inner diameters) and their assemblages as mineral component of natural rocks. Amount of layers in natural few-layered graphene nano-flakes varied from 19 to 45. Mechanisms of few-layered graphene nano-flakes generation in natural rocks are discussed.

在与其他碳纳米级矿物相共生关联中发现少层石墨烯薄片

在熔渣状高温冲击变质岩（多混砂岩）的石英和钾长石颗粒之间发现了少层石墨烯纳米薄片、多层碳纳米管、富勒烯和类富勒烯的间隙纤维状微米级聚集体。 ) 的 Dzharakuduk 地区 (Kyzyl-Kum 沙漠，乌兹别克斯坦)。这是首次发现少层石墨烯纳米薄片以及多层碳纳米管（内径约 10 埃）及其组合作为天然岩石的矿物成分。天然少层石墨烯纳米薄片的层数从19到45不等。讨论了天然岩石中少层石墨烯纳米薄片的生成机制。
