摘要
根据地层、构造及岩浆活动特征,中生代大杨树裂陷盆地的演化历史可划分为4个阶段,由早到晚分别为:①断陷初期火山强喷发伴随粗碎屑快速堆积阶段;②断陷中期火山弱喷发较稳定湖盆沉积阶段;③断陷晚期火山强喷发阶段;④断陷后整体抬升剥蚀阶段.大杨树盆地是发育于中国板块东北端的一个晚中生代裂陷盆地,盆地的形成、演化历史和充填特征,反映了其形成演化的地球动力背景具有受深部地幔热柱和西伯利亚板块、库拉—太平洋板块作用明显影响的特征.
The Mesozic Dayangshu Basin evolvement can be divided into 4 stages, which are ① initial rifting stage of strong volcanic eruption with speediness deposition of coarse clast; ②middle rifting stage of weak volcanic eruption with steadier deposition of lacustrine; ③later rifting stage of strong volcanic eruption; ④ subsequent rifting stage of uplifting and erosion. Dayangshu Basin is a Mesozic rifting basin developed in most northeastern of Chinese plate. The formation, filling and evolvement of the basin implied the geodynamics background of interaction of hot mantle plume, Siberian plate and Kula-Pacific plate.
