Rock fragments from the deepest parts of a buried hydrothermal system belonging to the Mesozoic Tethys Ocean entered as xenoliths in a Miocenic diatreme, hence brought to the surface, in the Hyblean Plateau (Sicily). Some xenoliths consist of strongly serpentinized ultramafic rocks bearing blebs of abiotic organic matter, where clusters of amorphous carbon nanoparticles, including nanodiamonds, are immersed. Such an occurrence conjures up established hypotheses that diamond surfaces are suitable catalytic platforms stimulating the assemblage of complex bio-organic molecules relevant to the emergence of life on Earth. The appearance of bio-organic molecules under primitive Earth conditions is one of the major unsolved questions on the origin of life. Here we report new micro-Raman spectra on blebs of abioticorganic matter from a selected xenolith. Diamond bands were related to hydrogenated nanocrystalline diamonds, with size of nearly 1–1.6 nm, formed from organics at low pressuresand temperatures. In particular, diamond surfaces can give rise to crystalline interfacial water layers that may have played a fundamental role in the early biosphere evolution as a goodmedium for rapidly transporting positive charges in the form of hydrated protons. Nowadays, proton gradients in alkaline hydrothermal vents along oceanic ridges are generally viewed askey pre-biotic factors. In general, serpentinites span the entire geological record, including prebiotic times. These hydrous ultramafic rocks often display evidence of abioticcarbon species, both organic and inorganic, including nanodiamonds, being also capable to giverise to chemiosmotic processes and proton gradients necessary to the organisms, such as the "Last Universal Common Ancestor" (LUCA), in the prebiotic Earth.

来自属于中生代特提斯海洋的地下热液系统最深部分的岩石碎片以异岩形式进入中新世奇缘，并被带入海底高原（西西里岛）的地表。一些异质岩由强烈蛇纹石化的超镁铁质岩石组成，这些岩石中含有非生物有机物质的气泡，无定形碳纳米颗粒（包括纳米金刚石）被浸入其中。这种情况可以证明已建立的假设，即钻石表面是合适的催化平台，可以刺激与地球生命的出现有关的复杂生物有机分子的组装。在原始地球条件下，生物有机分子的出现是关于生命起源的主要未解决问题之一。在这里，我们报告了来自选定的异种生物的非生物有机物起泡的新微拉曼光谱。金刚石带与氢化纳米晶体金刚石有关，其尺寸约为1–1.6 nm，是由低压和高温下的有机物形成的。尤其是，金刚石表面可能会形成结晶性界面水层，这可能在生物圈的早期发展中起着基本作用，作为以水合质子形式快速传输正电荷的良好介质。如今，通常认为洋脊上碱性热液喷口中的质子梯度是关键的益生元。通常，蛇纹岩覆盖整个地质记录，包括益生元时期。这些含水超镁铁质岩石通常显示出有机和无机非生物碳物质（包括纳米金刚石）的证据，它们也能够引起生物体所需的化学渗透过程和质子梯度，
