A DISCUSSION ON THE TECTONIC CHARACTERISTICS OF PENG-GUAN COMPLEX IN LONGMEN MOUNTAINS
Lin Maobing; Ma Yongwang
Peng-Guan Complex located in the middle section of Longmen Mountains is a huge and complicated geologic body in competitions. It formed in Precambrian. The researches on the profile and the geological mapping show that it is a tectonic slice with very strong deformation in the Longmen Mountain nappe belt, and that it is an exotic block deformed by the Strong tectonic Strain during the nappins from an ancient complex. The contact relation and replacement manner are tectonic origin. The hot replacement related can be recognized only within the tectonic slices. The deformational features within this complex are formed in the Indo-China-Himalayan orosenic period.
