Abstract The authros collected the soil samples uniformly above the target ore district and analyzed them with the near infrared spectrum. The results show that the NIR could identify the minerals in the soil well, including the combination of altered minerals roughly. Contrasting these mineral combination with the characteristics of orebody, we found that there was a certain degree of correlation between the soil and the concealed orebody, especially the altered minerals which was consistent with the altered conditions of this deposit. Therefore, we thought that any mineral composition of soil could be used to indicate some information from deep orebody and provide some basis for finding this type of copper. In addition, we also thought that the NIR information contained in the soil above the oreboday could serve as an effective research method inproviding some basis for prospecting . And we can use it for other deposits, especially for the deeply concealed orebody and some regions with a fragile geological environment.
