Contrast Study on Coalfield-Structure,and Tectonic Evolution in Jilin

摘要

Using contrast analytic method and take the coal-control structural pattern as the master line summarized the differences of coalfield structure characteristic in Jilin Province. Generally speaking, in the north, the extensional action is the most pattern, however, in the south of Jilin, the main structural pattern is compressions. In North, fault and block combination is the main pattern, the coal distribution range is relatively bigger; however, In south, the mainly are compression patterns such as the combination of reverse and thrust, thus, coal measures are obviously destructed and have smaller extent. Moreover, the structure difference above between south and north is also closely with their tectonic position and experience of tectonic evolution.
