2、期被動(dòng)陸緣不發(fā)育,多以裂陷槽為特征;前陸盆地發(fā)育階段多以陸相為主;晚期的強(qiáng)烈擠壓疊加了巨厚的山前沉積。多旋回的構(gòu)造運(yùn)動(dòng)和多期次的盆地疊加使中國(guó)的盆地多具疊合盆地的特征,影響到烴源巖的演化及油氣的運(yùn)移和分布。因此,中國(guó)的含油氣系統(tǒng)多為復(fù)合油氣系統(tǒng)。關(guān)鍵詞:板塊構(gòu)造;疊合盆地;前陸盆地;復(fù)合油氣系統(tǒng)中圖分類號(hào):TE111.1文獻(xiàn)標(biāo)識(shí)碼:AControlofplatetectonicsoverevolutionofpetroliferousbasinsandcharacteristicofoilandgasdistributioninChina
