The news ’more than 100 diamond were found in Aoshi area of Liping’ is reported,only 8 diamond in Huangsi,Liangsi and Datong of Liangjiang are found by professional geological team,the others are found by the local farmers.There is no any improvement for diamond prospection by times’ heavy-mineral measurement,geological investment and geochemical prospection,in order to strengthen the study of crystal shape,morphology of diamond and its possible origin,few diamond were bought from the local farmers.According to the information of ’no limitation’ from the local farmers,it’s thought the news of diamond are found in Aoshi should be doubted.It’s suggested to testify the factuality of diamond placer anomaly by stream sediment geochemical method with the studying targets of Cr,Co,Ni and Ti under the background of bed rock geochemistry,so muti-times work and high expense geophysical investment can be avoided.It also can determine the target area quickly,speed up the diamond prospection by other ways.
