Abstract According to geophysical field characteristics, seismic sounding, magnetotelluric sounding and recent geological data, the boundary between Chinese platform and Da Hingganling-Mongolian Paleozoic geosynclinal folded belt lies along Xar Moron River- Wenduermiaobei-Baiyinyanzhongxingaobaobei-Baoyintubei-Qeh-Talin tectonic line, and from Talin eastward, the geosyncline-platform boundary stretches along the northern boundary of Tarim platform; from Xar Moron River eastward, the geosyncline-platform boundary pinches out on the southwestern edge of Songliao Precambrian landmass.
