Latest Patents

Hongjun Cheng holds a patent titled "Method for rapid prediction of potential of porphyry copper mineralization based on spectral characteristics of tourmaline." This method involves collecting and collating data related to magma-fluid evolution, petrography, and mineralogy of a porphyry copper deposit in a working area. It systematically distinguishes magmatic tourmaline from hydrothermal tourmaline and further differentiates phases and generations of the hydrothermal tourmaline. The process includes collecting hydrothermal tourmaline samples, performing short-wave infrared spectroscopy measurements, and extracting spectral characteristics of the Fe—OH and Mg—OH wavelengths. The findings indicate that when the Fe—OH wavelength is less than 2245.75 nm and the Mg—OH wavelength is greater than 2356.57 nm, the area has significant metallogenic potential.
