摘要： 用开拓后的异常划分算子，根据实际资料从ΔＴ＿Ａ异常中分离出深部磁场，以裂谷地质观点指导进行定量计算、综合分析与研究，认为塔里木地区深部磁场是塔克拉玛干前震旦纪古裂谷的反映。该裂谷是古生代地台和部分中生代生油坳陷形成、发育的基础，也是控制塔里木盆地构造发展的基础，这一古裂谷的发现为塔里木盆地寻找大油气田指出了方向。

Abstract: Deep gcomagnetic field is picked from ΔTA anomalies on actual data with extended abnormal classification operators，and a quantitative estimation and comprehensive analysis of it are carried out in geologic theory of rift. It is concluded that deep gcomagnetic field in Tarim area is the evidence of Taklamakan Pre-Sinian paleorift, which is the basis for fotmation and evolution of Paleozoic platfarm and part of Mesozoic oil-farming depression as well as for controlling tectonic evolution in Tarim basin. Its discovery provides a guideline towards large-scale oil and gas fields in Tarim basin.
