Here I reported new structural data to answer above question, including field section observations and geologic map with large scale in a key area, accompanying with detail microstructural observations, quartz C-axial fabric analyses, and tectono-thermogeochronology (40Ar/39Ar and zircon SHRIMP U-Pb method). Taking available previous data into account, following progression is achieved:1. Completely rebuilding the post late-Paleozoic deformation history of the Harlik MountainFive stages of deformation were identified:(1)pre-Permian compression deformation which may have resulted from pre-Permian subduction;(2) earlier Permian post-collision extension;(3) middle Permian west-east directed dextral slip shearing;(4) later Permian nearly N-S compression deformation; and (5) later Cenozoic intra-plate N-S compressional deformation.

本文选择新疆东部哈尔里克山为研究对象，通过详细的野外路线地质构造调查和关键地区大比例尺地质填图，以及室内显微结构观察、石英岩组分析和构造热年代学(Ar-Ar和锆石SHRIMP U-Pb定年)研究，结合前人研究成果，取得了如下新进展：1、系统重建了哈尔里克山晚古生代以来的变形历史识别和确定了该区板块俯冲碰撞阶段的二叠纪以前挤压变形，后碰撞阶段早二叠世伸展变形、中二叠世近东西向右行走滑变形和晚二叠世近南北向挤压变形，以及板内演化阶段的晚新生代南北向挤压变形等5期构造变形事件。

通过对试验观测资料的处理和反演，并结合地质、物性资料进行综合分析，结果表明在南黄海盆地海底以下深部还存留有古生代地层，这对于南黄海前第三系含油气前景的评价具有重要意义。

Seismic energy is disturbed and attenuated seriously under the bad geological conditions for seismic exploration in southern Huanghai basin, and therefore the Meso-Paleozoic wave group of marine reflection seismic cannot be recognized and the seismogram does not meet the requirement for evaluation of pre-Tertiary oil/gas resources in southern Huanghai basin. In May 2006, marine magnetotelluric sounding experiment was carried out and reliable data were acquired.

针对南黄海盆地深层地震地质条件差，地震波受屏蔽，能量严重衰减，在海洋反射地震资料中很难识别反映中-古生界的反射地震波组，不能满足南黄海盆地前第三系油气资源前景评价的需要等问题，于2006年5月，开展了南黄海海域海底大地电磁测深试验，在盆地内五莲斜坡和胶州凹陷区布设了3个海底大地电磁测深点，取得了可靠的海底观测数据。
