1 地质背景
塔里木盆地为叠合盆地, 核心局部为海相古生 界克拉通[15,16]. 玛扎塔格构造带的形成演化与巴楚 凸起乃至塔西南坳陷的形成演化密不可分. 巴楚地 区经历了晚元古代盆地基底形成期、早古生代拉张裂 陷期、晚古生代隆升剥蚀-沉积期、中生代隆升剥蚀 期、新生代山前坳陷沉积、断裂活动期. 该区主要发 育有两组断裂: NW-SE 向断裂, NE-SW 向断裂. 其中 控制和田河气田发育的玛扎塔格断裂为 NW-SE 向断 裂, 其雏形可能是形成于早古生代拉张裂陷期的正 断层, 在晚古生代隆升期反转抬升, 并于喜马拉雅期 再次活动, 下部断裂为背冲式逆掩断层, 上部为平冲 式走滑逆掩断层. 喜马拉雅期是玛扎塔格断裂构造 带定型的关键时期, 晚喜马拉雅运动是造本钱区地 层出露的关键, 对玛扎塔格构造带进行一定程度的 改造
