摘要: 三十二年八月一日,由迪化南出,过红盐池。道在三叠纪地层中蜿蜒。及至芨芨槽子(1220公尺)距迪化十八公里,有断层。其西之岩作东西向;其东者则作东北两南向。二者相对倾斜。过此越分水(1350m)东南下坡入一槽形谷。谷最宽约百里,少亦有三十里,长则东南直抵达坂城西北渐收缩,趋乌鲁木齐之上源。与伊犁之崆吉斯河隔一分水,全长计约四百里。糟中亦非平坦无垠者。由芨芨槽子而东南低冈起伏,尽为红色岩层,层理清浙褶辍上指,似一被覆,掩於博格多山之西端之黑紫色斑岩上。

Abstract: This paper record, my geological and geomorphological observations enroute from Urumuchi to Aksu. Leaving Urumuchi on August Tst, we passed through the graben teough of Davan, followed the course of Bayan Ho to Toksun in the Turfan Basin. Glaci-fluvial deposits were seen in the val?ey of Bacanho at 980m, above the sea. Toksun city has an elevation read from a Paulin 133 metres. We travel south through the wadi of O-hu-Bulak and the Ma an-tso-ze Pass where granites and associated igneous and metamorphosed phenomena were observed. Glaci-fluvial silts and glacial moraines were found at 1400 and 1300 metres respectively, The mountain Summi has an old topography of arid climate, beinb subdue and deeply buried by weathered, angular debris with abundant dissected fans: on a rather plain-like surface. Hills rise only 2-300 metres above the general plain surface at 1500 metres. Grossing the frontal range of the Kuruktagh and the Depression of Singer, we finally leached Karashar. A great fan is seen on the NE. mouth of the Flm-valley (Yu-shu-wan) having a slope of one in twelve. No treea except a few Ulmus were seen. The wells reached 74 metres deep in the valley and 58 metres at Sin-tsin-tze, on the gobi beyond the valley. These are dug in gobi sediments and have not)et reached rock.
