| 摘 要： | 本文将晚白垩世王氏组的沉积相划分为五类:湖盆陡岸浊积扇相、洪积扇沉积相、滨—浅湖前缘斜坡相、次深湖相、湖湾相。并对其微相特征进行了详细研究。王氏组沉积特征所反映的沂沭断裂带之活动特点是:先为徐缓的脉动,而后是陡然激烈的断陷,故造成了补偿性沉积与超补偿性沉积的叠置。王氏组砂岩平均化学成分表明:马站盆地具弧后盆地性质。

| Abstract: | The sedimentary facies of the Cretaceous Wangshi Formation falls into five types of: lake basin--steep shore turbidite fan, sedimentation of pluvial fan, lake shore--shallow lake front edge slope, sub--deep lake and lake-bay. A detailed study is conducted of their microfacies characteristics. The activity of the Yishu fault zone reflected by the sedimentation characteristics of the Wangshi Formation initiates with a slow pulsation followed by a sudden and violent rift faulting, thus causing the superimposed... |
