Carbon nanotubes represent an impressive kind of materials with diverse unexpected properties. A new type of natural carbon nanotubes found in the Sujiquan graphite ore deposit, Xinjiang, China is presented and observed with high resolution transmission electron microscopy (HRTEM). This finding shows that all allotropic carbon forms known up to date can be produced in nature, and high temperature, pressure, catalysts particles seem to play an important role in producing carbon nanotubes. The forming conditions such as temperature and pressure of carbon nanotubes in graphitizing granite have been calculated. It has very important significance for scientist to design the condition of CNTs synthesis and utilize the ore deposit.
