     This paper attempts to date the loess from Ganzi area, Sichuan province, using a new method-TT-OSL protocol for OSL dating. A preliminary experimental study was conducted loess from the Ganzi-A section. Testing result showed that the naturally recuperated OSL signal intensity increases with depth of stratum, being obvious accumulation. A ＇ replacement plot＇ analysis was applied to test the reliability of the TT-OSL protocol and showed a nice result. The De values of 3 samples were measured by SMAR and TT-OSL protocols, respectively, and ages were calculated. The comparison between De.rrosL and De_SMAR show the former was greater than that of the latter, and comparison between the ages is as well. However the ages of TT-OSL method is less than the expected value from magnetostratigraphy. Based on the results, the TT-OSL method was applied to fine-grained quartz extracted from the Ganzi loess. But the reliability of results from TT-OSL dating needed to be tested and verified by more independent ages.
