英文摘要	Additional to deep seismic reflection survey[1]. MT; magnetic and gravity as well as radioactivity surveys have been applied in the crustal investigation in the Sulu ultrahigh pressure metamorphic (UHPM) terrane. The results of these non-seismic methods well be introduced in this paper. Two regional profiles of total length 126km are obtained from 2-D inversions, producing electrical resistivity and geomagnetic sections. The results include that (1) in agree with deep reflection interpretation, MT and geomagnetic profiles show similar the subduction and exhumation pattern of the Sulu UHPM rock slice; (2) these data provide not only constraints to seismic interpretation, also new evidences for heat flow uplifting, as well as existence of faults and geomagnetic bodies; (3) discovering a new fault of striking NNW, named Junan-Haizhou fault, which is very significant to reveal the regional tectonic evolution; (4) based on heat-flow uplifting, many granite intrusions, deep buried high-velocity lens,it seem that the northern Sulu area is not ideal site for deep scientific drilling project which aims revealing the mechanism of formation and exhumation of the UHPM slices. We will continue to present a paper involved in geophysical investigations in the southern Sulu UHPM terrane.
