5.Characteristics or zero point of charge of volcanic ash soils in Changbaishan and Wudalianchi.
6.GEOCHEMICAL FEATURES OF Sr,Nd,AND Pb ISOTOPES OF VOLCANIC ROCKS IN CENOZOIC ERA IN TENGCHONG, CHANGBAISHAN AND WUDALIANCHI,CHINA
7.THE TL CHRONOLOGICAL EVIDENCE OF THE RECENT ERUPTION IN WUDALIANCHI VOLCANIC CLUSTER
8.After breakfast, sightsee new-aged volcanic sightseeing areas: Black Dragon Hill (crater, stone sea), Buried-Hill (Birch forest, Bagua Lake,); sightsee the second and third lakes of the Five Great Chain Lakes, return to Harbin by bus.
9.We make measurements of radioactive gas Rn and Th on 12 measuring lines by using gaseous chemical method in Wudalianchi region.
10.as for the K-rich basalts from Wudalianchi volcanos,the cryst-allization of phenocrysts took place in the cource of slow ascent and coolingof the magma,as indicated by the decrease of homogenization temperatures ofmagmatic inclusions(from 1308~° to 1178℃)and CO_2 pressures(from 0.9 kbarto 0.4 kbar in the process of crystallization from olivine to clinopyroxene.
