- Project Results:
- An area of 88 square kilometers in the complex
Quinling Fold Belt was mapped. The Tiao Shai region is situated
in Zone II ('intense synmetamorphic thrusting and recumbent folding')
of Matteurs' (1985) tectonic zonation of the Qinling Mountain
Belt. The region is physiographically divided into three areas,
the northeast area, central-valley area and southwest area which
coincides with distinct petrological provinces. They consist
mainly of metamorphosed igneous and metamorphosed sedimentary
rocks intruded by a diorite complex. A wide variety of structures
occur in the region which include two sets of faulting, four
sets of jointing, four types of foliations, three phases of boudinage,
two minor igneous intrusions, three major igneous intrusions,
tension gashes, mineral lineations, six types of veins, xenoliths
and schlieren. Domainal regimes were indicated wherever possible
resulting in three major structural zones contained in seven
structural domains. A back arc - near arc environment is suggested
relating to two phases of subduction and four associated periods
of metamorphism.
