| 摘 要： | 我国陆上最深的钻井塔参1井位于塔里木盆地中央隆起,井深7200m,在井深3742～4001m钻遇志留泥盆系碎屑岩259m,包括下志留统125m,上泥盆统134m。在该段岩心采样23块(下志留统15块,上泥盆统8块),其全岩和微量元素地球化学分析表明,塔参1井的志留泥盆系碎屑岩均为稳定大陆克拉通内部的沉积,物源可能来自其底部以前震旦纪花岗岩为代表的古老陆壳基底。

| Abstract: | The Drilling Well of Tacan 1 (TC 1 for short) was an exploration well in the central part of the Tarim Basin, NW China. It was 7 200 m in depth and the deepest well on shore in China, so far. Its systematic core extracted was an important window for the studies on Tarim geology. The Silurian Devonian clastic rocks were revealed from the depth of 3 742 m to 4 001 m, including 125 m of Lower Silurian and 134 m of Upper Devonian. Total 23 specimens (15 of Lower Silurian and 8 of Upper Devonian) were collected for chemical analysis. The geochemical data showed that the sedimento tectonic setting was an inner cratonic environment. Namely, the Silurian and Devonian clastic rocks in the TC 1 area were deposited on a stable continental crust. The provenance might be the uplifted Pre Sinian basement rocks, which were represented by the granitoids revealed at the bottom of the TC 1. |
