| Aqishan-Yamansu belt is located in the eastern Tianshan acrogenic belt betweenYamansu breaking point and Aqikekuduke breaking point. This thesis made morein-depth exploration on the relations between tectonic evolution and mineralization ofthe the area by on-site investigating, appraising the microstructure in laboratoryunder the microscope, and collecting and analyzing the results of previous studies.On-site investigating and studying the microstructure of Aqishan-Yamansu belt showsthat the area developed series of tectonic deformation characteristics, such asstretching lineation, banded structure, S-C group structure, rotational fold, rotationalporphyroclast system, mineral orientation. The development of these tectonicdeformation shows that there are east to west deformational characteristics ofcharacteristics of ductile shear in Aqishan-Yamansu belt. The geological features ofYamansu Iron Ore, Weiquan Skarn Copper Mine and Kumtag Molybdenum Minegives a full explanation to the ore controlling functions of Aqishan-Yamansu beltdeformational characteristics of ductile shear. Therefore, closer examination to themicrostructure of the area has important theoretical and practical meanings. |
