In this paper

We mainly present the method of exploring gold deposits covered by original soils from weathered rocks by means of analyzing and studying the laboratory spectrum’s relationship of both original soil and its weathering mother

r

ock. In western Qinling Mountains

there are several large scale gold deposits in metallographic provinces. In the past

remote sensing technology was used to investigate this area

however

gold deposits exploration still have not been broken out. As bed

r

ocks are covered by vegetation and soils

it is very difficult to efficiently apply remote sensing technology. During our study of remote sensing information characteristics on the earth

we found that most bed

r

ocks are fortunately covered by original soils in gold metallographic provinces. Therefore

we hope that gold deposits covered by original soils can be directly determined by using the spectrum features of the soils overlain the bed

r

ocks. The analyzed relevant samples were collected from several typical known gold mining areas

Pearson’s correlation analysis was adopted in order to study the linear correlation between soils and their corresponding rocks

at the same time

the obtained correlation coefficients were tested by means of Two

t

ailed method. To single layer samples （original soil directly covers bed

r

ock）

their correlation coefficients are in high positive relationship

the average number is about 0 942. To multi

l

ayer samples （more than one soil layer cover the bed

r

ock）

the correlation coefficients are lower

however

there are still 0 763 in positive correlation. According to our results

we can conclude that there is a high positive relationship to the spectrum of both original soil and its weathering mother

r

ock. It is possible for us to extract gold deposits information from covering original soil’s spectrum and provide a new method for gold deposits exploration.
