敦化盆地是由白垩—古近纪的新开岭盆地、大山嘴子—镜泊湖盆地和新近—第四纪敦化火山盆地的组合总称。它的形成严格受敦密断裂带地堑式两条平行断裂所控制。敦密断裂带在侏罗—白垩纪时期受伊佐奈歧板块的向西俯冲、挤压形成的火山造山带的地堑式断裂带,而新近—第四纪则主要受长白山火山地幔热柱和太平洋板块向西俯冲带而形成的不完整复式裂谷型深大断裂带而形成。经普查,大山嘴子—镜泊湖盆地具有良好的成煤和成油条件,并且已初步探明煤矿地质储量5.82亿吨,远景储量10亿吨;油气总资源量为1.24亿吨。敦化火山盆地的玄武岩喷发期次多,分布也很广,造就了许多风光景点及优质板材、铸石、纤维、硅藻土等资源。

The Dunhua Basin is a collective of Cretaceous-Paleogene Xinkailing Basin,Dashanzuizi-Jingbohu Basin,and Neogene-Quaternary Dunhua Volcanic Basin.Formation of the Dunhua Basin was controlled strictly by the two parallel graben faults in the Dunmi Faults Zone.The Dunmi Faults Zone was a series of graben faults in the volcanic orogeny that formed by the westward subdction and compression of the Yizuonaiqi plate during Jurasy-Cretaceous.During Neogene-Quaternary the mantle thermal plume beneath Changbaishan and the westward subduction of the Pacific Ocean made the composite but non-integrity graben deep faults zone,composing the Dunhua Basin.It shows,from a geological survey work,that there exists a proper environment for producing coal and oil in Dashanzuizi-Jingbohu Basin.And it did prove up a principium reserve of five hundred eight-two million tons,perspective reserve of one billion tons of coal and one hundred twenty-four million tons of natural gas and oil.The basalts in Dunhua Basin were formed multiply and distributed on a wide area,which brought up the many beautiful scenery and resources such as building material,casting and rock-cotton and diatomite.
