新疆准噶尔盆地东缘克拉美丽地区双井子剖面滴水泉组孢粉组合中有孢粉化石２９属３０种，具环孢占优势，含量为５７．９％，其中Ｃｒａｓｓｉｓｐｏｒａ（２３．６％）、Ｓｔｅｎｏｚｏｎｏｔｒｉｌｅｔｅｓ（１４．３％）的含量最高；无环孢居次，含量为３４．５％，以Ｐｕｎｃｔａｔｉｓｐｏｒｉｔｅｓ（１２％）和Ｅｅｉｏｔｒｉｌｅｔｅｓ（７．１％）为主。地质时代为早石炭世晚期，可能属韦宪期早期，大致相当于甘肃靖远臭牛沟组下段Ⅰ孢子组合带和西欧的Ｐｕ孢子组合带。当时为亚热带温暖湿润气候。
There are 30 species of 29 genera of Sporopollen in the Shuijingshui Formation of Shuangshuiquan Formation in Shuangjingzi Section of the Kelameili Basin, eastern margin of Junggar Basin, Xinjiang. The content of Cyclospora is 57.9%, including Crassispora (23.6%), Stenozonotriletes (14.3%) was the highest content. The highest content of non-cyclosporidium was 34.5%, which was mainly Punctatisporites (12%) and Eeiotriletes (7.1%). The geologic age is Early Carboniferous, possibly belonging to the Early Wei Xian Period, roughly equivalent to the sporozoite assemblage of the Lower Silurian Formation in Qujing, Gansu Province and the Pu spore assemblage in Western Europe. Was warm and humid subtropical climate.
