The results of close mapping of areas of recent thrusts in the Central Tien
Shan demonstrate that they are an element of intricately built shear zones
. A system of conjugate diagonal faults of NW and NE strikes which are seco
ndary with respect to the marginal ones develops within sublatitudinal bloc
ks bordered by sinistral reverse faults and strike-slip faults. Mass motion
along the system of conjugate faults brings about local compression zones
in the apices of wedge-like blocks. In the natural geologic structure, thes
e zones are compensated by major reverse faults and thrusts. When the thrus
ts came out to the surface, the frontal part of the allochthon was destroye
d, which is marked by Neogene-Early Pleistocene tectonic gravitational mixt
ites. The described structure of the shear tones formed In a transpression
setting.
