This paper analyzes the data of gravity and magnetic anomaly field in scale of 1�� 200 000�� borehole and measuring density in Anshan - -Benxi area�� Through the method of 2 - -D human- computer interactive inversion under the geological section data constraints��the authors complete the deeply geological structural inversion of 14 profiles�� The inversion results confirm the constitution of Archean crystalline basement in Anshan- -Benxi area��in which the maximum buried depth is about 4 500 meters in Xialiaohe Basin��while the shallow area of the buried depth is located in the south of Benxi City�� In speculation��Tianshifu town and south of Pingdingshan town may have concealed iron ore��
