哈拉奇地区位于西南天山南侧、塔里木盆地西北缘,是塔里木板块和哈萨克斯坦-西伯利亚板块碰撞的前锋区域。出露了寒武纪—二叠纪变质程度较浅的地层;新发现其存在奥陶系—志留系平行不整合、泥盆系—石炭系平行不整合和二叠系—中、新生界角度不整合共3个不整合面,并以阿尔帕确依切克穹窿式复背斜为界,两侧志留系—二叠系沉积环境存在较大差异,组成背斜的奥陶系、寒武系与上覆地层变质作用也不同。奥陶系—志留系平行不整合与区域上祁连运动相对应;泥盆系—石炭系平行不整合同天山运动中期相吻合;二叠系—中、新生界角度不整合为天山运动末期的影响造成。
Located in the southwest of the southwest Tianshan Mountains and the northwestern margin of the Tarim Basin, the Halaqi area is a striking frontal area between the Tarim plate and the Kazakhstan-Siberia plate. The Cambrian-Permian strata of lower Permian metamorphism are revealed. The Ordovician-Silurian parallel unconformity, Devonian-Carboniferous parallel unconformity and Permian-Mesozoic-Cenozoic There are three unconformities in the angle of unconformity. Based on the Arpa and Czechkian complex anticlines, the Silurian-Permian sedimentary environment on both sides is quite different. The Ordovician, Cambrian and overlying strata metamorphism is also different. The Ordovician-Silurian parallel unconformity corresponds to the Upper Qilian movement in the area. The Devonian-Carboniferous parallel unconformity coincides with the mid-Tianshan movement. The Permian-Mesozoic-Cenozoic angle does not conform to the Tianshan movement Impact caused.
