巴楚——麦盖提T50不整合面剥蚀量恢复及古地貌特征

Restoration of Erosion Amount and Paleo-Geomorphological Feature of Bachu-Markit T5 0 Unconformity

针对巴楚一麦盖提地区的复杂地质特征，利用地层结构外延法恢复巴楚一麦盖提地区的T5 0（二叠系沉积末）不整合面的剥蚀趋势和平面分布特征，并恢复二叠系末的古地貌特征。T50不整合面历经较长时间，剥蚀量较大．剥蚀量在700-2000m之间，二叠系沉积末形成6个局部古隆起，隆起最大高差为700m，最小高差为300m。

Considering the complicated geological features of Patrul-Markit region, this paper utilizes strata structure extrapolation to recover the corrosive trend and plane distribution features of T~ （end of Permian sedimentation） unconformity surface of Patrul-Markit region, as well as paleo-geomorphological features of Permian end. T5 0 unconformity surface has experienced for a long time, with large quantity of denudation within 700-2000m. Six local palaeohigh formed at the last stage of Permian sedimentation, with the maximum altitude difference of 700m, and minimum 300m.
