外部构造系统对松辽残留地台构造的干扰与改造

松辽残留地台区中的构造型相与伊陕,四川残留地台区的构造型相比较,既有稳定区构造型相的同一性,又有较大的特殊性,其特殊性在于局部地区系统性较强,并出现了较多的逆冲断层。通过运用＂壳体＂构造理论分析,作者初步认为它是外部构造系统干扰和改造的产物。据此对松辽地北部地段的油气远景评价提出了一些新的看法和建议。

THE DISTURBING AND REFORMING OF EXTRINSIC TECTONIC SYSTEMS FOR THE SONGLIAO PLATFORM STRUCTURE

Compared with the Yishan Platform and Shichuan Platform, the structural style of the Songliao Platform not only has the same aspects as those of a stable region, but also has. more speciality, which lies lies in that some parts of Songliao Basin have developed certain structural systems and more thrusts. Using "crustobody" theory, the authors believe that they are due to the disturbing and reforming of extrinsic tectonic systems. Based on these facts, the authors therefore obtained more new understandings of the oil-gas prospecting evaluation in the northern region of Songliao Basin.
