| 摘 要： | 本文主要根据二维地震剖面并结合野外露头的分析认为,十万大山盆地东南缘的基底断裂是钦防海槽向北西冲断-推覆的前锋断层,断裂两侧的中、古生界在地层层位与厚度上存在明显差异。钦防海西-印支海槽的西界不应是灵山断裂,而应是十万大山盆地东南缘的基底断裂,其范围远大于现今博(白)—罗(定)—广(宁)断裂与灵山断裂之间的范围。基底断裂为一无根的推覆构造带,其下掩覆了十万大山盆地东南缘的许多区域,是下一步油气勘探的重要领域。 |
| 关 键 词： | 推覆构造 断裂 十万大山盆地 钦防海槽 |

| Abstract: | Based on geological interpretation on the 2-D seismic profile as well as outcrops, the paper presents the idea that the basement fault is an important structural boundary, on both sides of which the Mesozoic and Paleozoic strata vary greatly in the sequence and thickness. And the western boundary of Qinzhou-Fangchenggan depression from Hercynian to Indo-Chinese epoch is not Lingshan fault but basement fault. The area of the depression is much bigger than that of the structural zone between Bobo-Luoding-Guangning fault and Lingshan fault. Large area of the Shiwandashan basin is covered by the basement fault, which is an important and potential petroleum exploration area for further working. |
| Keywords: | overthrust fault Shiwandashan basin Qinzhou-Fangchenggan depression |
