通过对风火山盆地白垩系砂岩薄片的粒度统计分析,划分出3种概率累计曲线,代表3种沉积相,分别为三角洲、河流和湖泊;并对研究区的沉积环境进行了划分,确定了该区为一套陆相沉积环境。这对于研究风火山盆地有重要的地质意义。而且对于该区找矿有重要的现实意义。
Through the statistical analysis of the grain size of the Cretaceous sandstones in the Fenghuoshan Basin, three kinds of probability cumulative curves are divided into three types of sedimentary facies, which are delta, river and lake respectively. The sedimentary environment of the study area is divided into two parts, The area is a continental depositional environment. This is of great geological significance for the study of the Fenghuoshan basin. But also has important practical significance for ore prospecting in this area.
