| 中文摘要: |
| 研究矿区位于松辽盆地北部东南断陷区西侧的徐家围子断陷沙河子组,成矿地质条件良好,本文运用沉积地质学研究方法,结合盆地周缘露头剖面和钻井、测井等资料,开展对沙河子组各沉积相类型的研究。在松辽盆地北部东南断陷区西侧徐家围子断陷沙河子组辫状河三角洲中共识别出辫状河三角洲平原和辫状河三角洲前缘 2 种亚相类型,并进一步划分为8个微相。 |
| 英文摘要: |
| The Shahezi Formation of Xujiaweizi Fault Depression, located in the west side of the southeastern fault depression in the north of Songliao Basin, has a good metallogenic geological condition. In this paper, the sedimentary facies types of Shahezi Formation are studied by using the method of sedimentary geology combined with the outcrop profile, drilling and logging data around the basin. In the braided river delta of Shahezi Formation of Xujiaweizi Fault Depression on the west side of southeastern fault depression in the north of Songliao Basin, two sub-facies types of braided river delta plain and braided river delta front were identified and further divided into eight micro-facies. |
