The Qinghai-Tibet Plateau existed 30,000 years ago?

On March 20, the Tibet Institute for the Protection of Cultural Relics held a three-day archaeological public sharing conference, where experts from the Chinese Academy of Sciences, Shaanxi Archaeological Research Institute, Sichuan University and other institutions gathered with local scholars to exchange and share the latest archaeological achievements in Tibet on 11 topics, the most notable of which was the archaeological excavation of the Niamu base in Tibet. The Qinghai-Tibet Plateau was first discovered with the exact formation and date of the archaeological site of pale stone, the site has been selected in 2016 China's top 25 archaeological discoveries, the interpretation of late laboratory artifacts is expected to solve the ancient human first set foot on the Qinghai-Tibet Plateau, where they came from, why climbed the plateau and a series of mysteries.
Decryption of the Natural Environment: 30,000 years ago, the warm, humid and suitable for human survival of the Tibetan North Plateau The nia woody site was jointly excavated by the Tibet Institute of Cultural Relics and the Institute of Paleontology and Paleoanthropology of the Chinese Academy of Sciences.
after more than 30 days of field work, the preliminary determination of the site at least 500 meters east-west, north-south distribution of at least 2000 meters, the surface has a large number of stone-making distribution.
Xiaoling, an associate researcher at the Institute of Paleontology and Paleoanthropology of the Chinese Academy of Sciences, said that according to the preliminary results of the photoresponsive age data, the nia woody site could be at least 30,000 years old.
isotope phase 3 (MIS 3), which is a record of oxygen isotopes obtained from samples of deep-sea cores, reflecting past temperature information and showing alternates of cold and warm in the Earth's ancient climate.
" MIS 3 is an important period of human evolution and paleontry culture research, more suitable for ancient human survival.
Habib, director of the Tibet Institute of Cultural Relics, said the period was a relatively humid small ice scale during the cold, dry last ice age and a key period for the origin and evolution of modern people in China and even East Asia.
archaeological discoveries and studies at home and abroad show that human activities were very active during this period around the world, not only the number of sites and sites is widely distributed, a large number, but also the human culture has made significant progress and changes.
the discovery of the remains of ancient human culture at the base of Thenia wood not only represents that the tibetan north plateau may have been in a warm and humid environment during this period, but also reflects the ability of the ancient humans in the late 1980s to adapt to the ecological environment of the plateau.
Culture is unique: unearthed many stone leaf tools popular in Africa, Europe and West Asia in 2016, with the approval of the State Administration of Cultural Relics, the Tibet Institute of Cultural Relics and the Institute of Paleontology and Paleoanthropology of the Chinese Academy of Sciences carried out archaeological excavations of the Nia woody site.
about 5,000 artifacts have been unearthed, including stone tablets, stone leaves, stone cores and stone cores, as well as tools including scrapers, sharps, engravers and dents.
" unfortunately, no human bones have been found at present, but the cultural relics unearthed at the base of the Nia wood show that its cultural appearance is unique, stone leaf technology as the main cultural features, prismatic stone leaf core number is more, Levawa prefabriced stone core has a small number of discoveries.
" Habib introduced, this stone leaf processing technology is mainly popular in Africa, Europe and West Asia and other places in the late Stone Age, in the Chinese mainland of the heritage of the Old Stone culture and technology is not developed, but at present in individual parts of China have been found, such as Xinjiang, Ningxia and Heilongjiang.
the emergence of this technology in the Qinghai-Tibet Plateau is of great significance to the exploration of the migration and exchange of people and culture. the emergence of
" stone leaf processing technology shows that 30,000 years ago there was the possibility of cultural exchanges between East and West, this speculation can only be determined after further comparison with the ancient Stone Age sites around the Qinghai-Tibet Plateau.
certainly does not rule out that this stone leaf processing technology is a local independent origin.
," Zhang Xiaoling said, stone leaves are more complex, unique, relatively high degree of standardization of stone products, it represents the more advanced productivity of that era.
although they are not exquisite stone, not particularly typical stone leaves, but for the study of the preservation of sites, buried information are very important.
Historic value is significant: filling the gap in the cultural landscape of the Ancient Stone Age in Tibet It is understood that, to date, there are about 95 stone-making sites in Tibet, of which 8 are recognized by the academic community, but all the stone specimens from these sites are taken from the surface, lack of reliable stratifice basis, the age is difficult to determine.
, the discovery and excavation of the Nia woody site is of great significance, it is the first time in the hinterland of the Qinghai-Tibet Plateau to find an Ancient Stone Age archaeological site with exact formation and dateological basis.
"We conducted detailed anthology, environmental magnetism, spore powder, silicon implants, and organic carbon isotope sampling and analysis of the profile.
currently collected a total of 38 photoel effect samples, environmental magnetism samples 116, spore powder, silicon implants and organic carbon isotope samples 116.
preliminary results show that the site is 30,000 years ago, detailed age data need to wait until the laboratory results.
," Zhang Xiaoling said.
As the "roof of the world" and "the third pole of the earth", the vast Qinghai-Tibet Plateau has an average elevation of more than 4000 meters, and the natural environment is harsh, which poses a serious challenge to the survival, migration, communication and development of mankind, especially the ancient human beings.
of high cold, lack of oxygen and scarcity of biological resources restrict the pace of ancient human migration and development of the Qinghai-Tibet Plateau.
" Nia wood-bottomed sites have a wide distribution area and rich cultural relics, which not only fill the gap in the cultural face of the Old Stone Age in Tibet, on this basis gradually establish the cultural framework of the times and related, but also explore the process of human development of extreme environment, and see its adaptability and viability.
