This paper has established six ground_space correlation models based on a study of ground spectrum property of kimberlites in Mengyin area. The TM correlation analysis of ground spectra of kimberlites led to the transformation of the TM image for the middle part of Yishu Fault zone into a ground space correlation image related to the ground spectrum property of kimberlites in Mengyin area. The application effects of the ground-space correlation image for the prognosis of diamond deposits in the middle part of Yishu Fault zome are also discussed in this paper. Through the analysis of the ground-space correlation image, the authors recognized six image anomalies related to the kimberlites. During the field inspection of the anomalies, some carbonate veins were discovered within A-1 and A-2 anomalies. Heavy mineral, isotope and REE studies suggest that this sort of carbonate veins might be a kimberlite which experienced late carbonate alteration.
