英文摘要 | The fine crustal structure and deep-shallow tectonic features of Beijing region are explored by using a 100 km long, NW-trending deep seismic reflection profile. This profile passed through the Sanhe-Pinggu earthquake (M8.0) area and main faults in Beijing region. The results show that the crust beneath the investigated area is divided into upper and lower crust by a strong reflective zone at about 6 similar to 7 s TWT. The thickness of the upper and lower crust is about 1821 km and 13 similar to 15 km, respectively. There are rich reflective layers and clear structural patterns above 3 similar to 4 s TWT as well as obviously different structural features along the profile. In the western region of Sanhe-Pinggu earthquake area, the stacked deep seismic reflection section shows 2 similar to 3 groups of strong reflective layers and a series of basement faults. In the eastern region of Sanhe-Pinggu earthquake area, there is a set of dense, westward-dipping, reflective strata with relatively strong energy, which have the typical characteristics of sedimentary basin. The largest depth of the sedimentary basin is about 8 similar to 9 km. The crustal deep fault revealed by deep seismic reflection profile has a steep fault plane, and it cuts and disturbs the lower crust and crust-mantle transitional zone. This deep fault extends upwards into the upper crust, and joins the crustal deep structure to the shallow fault. The profile reveals that the deep-shallow fault system, represents the major deep-shallow tectonic feature in the study region. |
