海拉尔盆地阿拉尔—罕达盖重磁电剖面深部结构特征及其地质意义
|
摘要
通过电磁场偏移成像处理技术,探索地震屏蔽层以下深部地质构造特征,揭示了海拉尔盆地深部存在似层状的电性异常,具有复式背斜的构造形态。盆地内各凹陷具有重力低、磁力高、电阻率低的重磁电特征;沉积地层为低频低幅度磁异常,岩浆岩为高频高强度的磁异常;剖面中东部电阻率存在低—高—低3层结构,岩浆岩呈高电阻率特征,古生界呈中低电阻率特征。德尔布干断裂与乌奴尔—鄂伦春断裂控制了深部古生界分布,古生界埋深为2~6 km,厚度为2~4 km;古生界与元古宇的接触界面呈复式背斜的构造形态,由3个背斜构造组成,对浅部凹陷分布有一定的控制作用。海拉尔地区晚古生代石炭纪发育泥岩、页岩、灰岩、板岩,推测盆地覆盖区可能具有一定的油气勘探前景。
By means of migration imaging technique of magnetotelluric data,and to explorat the characteristics of converted-wave layer below the deep geological structure,it is reveals the existence of composite anticline.Depressions within the basin have the features with low gravity,high magnetic and low resistivity,the sedimentary strata shows low-frequency and low-amplitude magnetic anomaly,magmatic rock have high-frequency and high-intensity magnetic anomaly,resistivity shows a three-layer structure of low-high-low in middle and eastern part of the profile,the magmatic rock has high resistivity and Paleozoic has low resistivity.Paleozoic strata exist in deep controlled by Derbugan and Wunuer-Elunchun fracture,with the depth of 2- 6 km and thickness of 2- 4 km.Paleozoic was composed with three anticlines,and the interface play a certain role in controlling of the shallow sag distribution.Mudstone,shale,limestone and slate are well developed in Late Paleozoic Carboniferous of Hailar basin,with these results we predicated that there are a good prospect for oil and gas exploration.
