Short answers, pulled from the story.
The Tarim Basin is an endorheic basin in Xinjiang, Northwestern China, covering about 888,000 square kilometres. It is bounded by the Tian Shan mountains to the north and the Kunlun Mountains to the south, with the Taklamakan Desert dominating most of its interior. The Uyghur name for it is Altishahr, meaning 'six cities'.
The Tarim Basin contained three main Silk Road routes: a northern route, a southern route, and a middle route through the Lop Nur region. The middle route was the shortest but became deserted after the 6th century when the Lop Nur region turned uninhabitable. Caravan routes shifted over time based on changes in the Tarim River's course and political conditions along the Gansu Corridor.
The Tarim mummies were found in sites including Loulan and the Xiaohe Tomb complex in the eastern Tarim Basin. Genetic analysis indicates they belonged to a distinct population of primarily Ancient North Eurasian descent with significant Northeast Asian admixture, unrelated to later Indo-European pastoralists such as the Afanasievo. A 2025 study by Zhang et al. found that a Late Bronze Age site in the far west of the basin, dated 1600 to 1400 BC, was overwhelmingly populated by descendants of the Sintashta and Andronovo peoples.
The Karakhanid Sultan Satuq Bughra Khan converted to Islam in 966, making the Karakhanids the first Islamic Turkic dynasty. The Karakhanid leader Yusuf Qadir Khan conquered Khotan around 1006, ending its existence as an independent Buddhist state. News of the conquest prompted the sealing of Dunhuang's Cave 17, which preserved a cache of Khotanese literary works.
China National Petroleum Corporation's exploration between 1989 and 1995 identified 26 oil- and gas-bearing structures in the Tarim Basin. Methane comprises more than 70 percent of the natural gas reserve. In 2015, Chinese researchers published findings of a vast, carbon-rich underground sea beneath the basin.
In 2025, China completed a 750-kilovolt extra-high voltage power loop running 4,197 kilometres around the Tarim Basin, connecting wind, solar, thermal, and hydropower sources across five prefectures. The project took 15 years and required nearly 10,000 transmission towers and nine substations. It increased the region's power transmission capacity from 300,000 kilowatts to 3 million kilowatts and connects with the grids of Qinghai and Sichuan.
