| Abstract: | The characteristics of the carboniferous structure in QilianAlashan area are studied in the paper, and the area is divided into three secondary tectonic units from south to north:continental marginal active belt, QilianAlashan semicraton and Zongwulong aulacogen. The continental marginal active belt can be divided into three tertiary tectonic units. Three tertiary tectonic units are also contained in QilianAlashan semicraton. Every unit is studied in detail, and finally the advantageous exploration district of oil and gas in the area is pointed out. |
