| 摘 要： | 本文从松嫩盆地扶余、榆树地区白垩纪姚家组岩石组合、韵律变化、厚度及区域分布入手,研究了姚家组岩石地层与沉积环境特征。该区姚家组下部为褐红色泥岩与灰绿色泥岩互层,其沉积环境属浅湖相沉积;中部为棕红—砖红色泥岩,其沉积环境属滨湖相沉积;上部为紫红—棕红色泥岩夹灰绿色粉砂质泥岩,其沉积环境属浅湖相沉积。

| Abstract: | Songnen Basin is an important composing part of the Songliao,among which,the retaceous strata develop,especially Yaojia Formation rocks.On the basis of the Cretaceous,Yaojia Formation rock association,rhythmicity,thickness and regional distribution,studied Yaojia Formation petrostratigraphy and sedimentary environment.There are interbedded brown-red mudstone and gray-green mudstone,the sedimentary environment belongs to shallow-lake sedimentation;The middle part is brownish red-brick red mudstone,the sedimentary environment belongs to lakeshore sedimentation;the upper is violet red-brownish red mudstone with grey green silty mudstone,the sedimentary environment belongs to shallow-lake sedimentation. |
