Nano-scale science and technology has achieved great successes in the field of eart sciences. Mineralogy is a major basic science in earth sciences and clay mineralogy occupies an important place in material science. It seems necessary to set up the subject of nano-scale clay mineralogy". The research method of nano-scale clay mineralogy is consistent with nano_scale science and technology, whereas the research content of nano-scale clay mineralogy consists of particle mineralogy, physics, chemistry, material science and processing technology. This paper deals further with the detection method and the analytical standard of nano-scale clay mineral as well as the industrial production of the compound polymer/nano-scale clay mineral material.
