Abstract

The Iraqi territory is located in the northeastern part of the Arabian Plate covering the collision zone with the Eurasian (Iranian) Plate in the northeast. This collision, which is still active with convergent tectonics, has caused deformation in the rocks of the Zagros Mountains with different intensities. The deformation intensity decreases southwestwards with exerted stresses from the collision in the NE–SW direction. Depending on the deformation intensity and other tectonic factors, the Iraqi territory is divided into three main tectonic units, these are from NE to SW: (1) Shalair Terrane, (2) Outer Platform, and (3) Inner Platform. Accordingly, the Inner Platform is less deformed as compared to other tectonic zones. Neotectonic evidence has been documented across all tectonic zones of Iraq; even within the Inner Platform which was assumed to be a tectonically stable zone. This study presents different Neotectonic evidence and their role in updating the tectonic framework of Iraq, confirming that the so-called Stable Shelf or Inner Platform units, which are considered tectonically to be undeformed are deformed by Neotectonic activity.

伊拉克（阿拉伯板块北部）的新构造迹象：分析概述

摘要

伊拉克领土位于阿拉伯板块东北部，覆盖东北部与欧亚（伊朗）板块的碰撞带。这次碰撞仍然活跃，具有聚合构造作用，导致扎格罗斯山脉的岩石发生了不同强度的变形。由于碰撞施加的应力沿 NE-SW 方向，变形强度向西南方向减小。根据变形强度和其他构造因素，伊拉克领土从东北到西南分为三个主要构造单元：（1）Shalair地体，（2）外台地，（3）内台地。因此，与其他构造带相比，内平台的变形较小。伊拉克所有构造带都记录了新构造证据；即使在被认为是构造稳定区域的内平台内也是如此。这项研究提出了不同的新构造证据及其在更新伊拉克构造框架中的作用，证实了所谓的稳定陆架或内平台单元，它们在构造上被认为是未变形的，但由于新构造活动而变形。
