Abstract

Abstract:

The northeastern region of the Pamir Plateau marks the convergence of the Pamir Plateau, the Tianshan Mountains, and the Tarim Basin. This area is associated with high levels of seismic activity and has experienced significant casualties due to several major earthquakes. In this study, earthquakes are relocated using the double-difference relocation algorithm, based on seismic observation reports from the China Earthquake Networks Centre(CENC)covering the period from 2008 to 2023. A total of 916 earthquake focal mechanisms were collected from various institutions and studies, including the GCMT, WWSSN, previous research, and the Xinjiang Earthquake Agency. The magnitudes of these events range from M2.8 to M8.2, and the time span extends from 1902 to 2024. The tectonic stress field was inverted using a spatial-temporal stress inversion algorithm with a 1.0°×1.0° grid, based on these historical focal mechanisms.
The relocated earthquakes are distributed along major tectonic zones situated between the Pamir Plateau, the Tianshan Mountains, and the Tarim Basin, forming several seismic clusters within the study area. Most events have focal depths of less than 30km. Seven cross-sectional profiles were selected to analyze the spatial distribution of seismicity. The regional tectonic stress field is primarily dominated by strike-slip and reverse faulting regimes. The maximum principal stress axes are compressional in a nearly horizontal south-north(S-N)direction, while the minimum principal stress axes are extensional in the east-west(E-W)direction, with either horizontal or vertical plunges. Based on the spatial distribution of seismicity and tectonic features, the study area is divided into several subregions: the central Pamir Plateau and its eastern and western flanks; the collision zone between the Pamir Plateau and the Tianshan Mountains and its surrounding areas; the Tianshan Mountains; and the interior of the Tarim Basin.
Preliminary results of earthquake relocation show that focal depths in the southeastern and northwestern parts of the Qimugen Arc Tectonic Belt are deeper than those within the belt. This is attributed to the subduction of the eastern and northeastern Pamir beneath the Tarim Basin toward the east and northeast. Accordingly, the Moho depth is also greater in these regions. These observations suggest that the Qimugen Arc Tectonic Belt represents a key tectonic boundary, with both the Moho and earthquake depths shallower within the belt than in its southeastern and northwestern margins. Focal depths along the southern margin of the Tianshan Mountains are deeper than those in the adjacent Tarim Basin, which is consistent with a deeper Moho in the former. Similarly, both the Moho and earthquake depths within the Ferghana fault and Piqiang fault zones are greater than those outside these faults along the southern margin of the Tianshan Mountains, indicating that these faults serve as significant tectonic boundaries. An area of sparse seismicity overlaps with the source region of the 1902 Atushi(Kashgar)M_W7.7 earthquake, suggesting that accumulated crustal stress was likely fully released by this event. Seismicity in the Tarim Basin primarily consists of aftershock sequences from the 1996-1999 earthquake clusters and the 2003 Bachu-Jiashi M_S6.8 earthquake. The main contributing factors to seismicity in the Tarim Basin are thought to be its low seismic wave velocity, low crustal density, and brittle crustal properties.
The initial results of the tectonic stress inversion indicate that the central Pamir Plateau is undergoing east-west lateral extension under a strike-slip stress regime, driven by compression from the Indian Plate to the south and obstruction from the Tianshan Mountains to the north. A normal faulting regime in the central grid of the Pamir Plateau is interpreted as a center of expansion or gravitational collapse. The tectonic stress field exhibits significant variation across the flanks of the Pamir Plateau. The R-value, stress regime, and plunge of the maximum principal extension axes show gradual and, in some areas, abrupt changes from the central region to the western and eastern margins, as well as in the collision zones between the Pamir Plateau and the Tianshan Mountains. The Tianshan Mountains continue to uplift due to near S-N compression, displaying a dominant reverse faulting regime. In the Bachu uplift and depression region in the southwestern Tarim Basin, the stress field is characterized by both reverse and strike-slip regimes, likely resulting from differences in crustal velocity, density, and structural composition.

摘要：

帕米尔高原东北部地区构造变形复杂、地震活动强烈, 分析其地震分布特点和构造应力场特征, 有助于探讨该区域复杂多变的构造变形特征及其孕震环境。文中基于中国地震台网中心地震观测报告和从多方面搜集得到的震源机制数据, 运用HYPODD方法和SATSI方法分别进行了地震重定位和构造应力场反演, 获得了研究区内整体地震活动和构造应力场分布特征: 1)研究区内震源深度分布与地壳厚度呈正相关。2)齐姆根弧形构造带、费尔干纳和皮羌断裂两侧的震源深度存在明显差异, 表明这些构造可能为重要构造分界线。3)1902年阿图什 M_W7.7 地震周边地壳应力释放充分, 导致天山山脉和塔西南坳陷交界地区小地震分布稀疏。4)受印度板块自南向北的推挤作用影响, 帕米尔高原、天山山脉和塔里木盆地均呈现近SN向的低倾角挤压应力场。5)研究区内的构造应力场呈现出明显的构造差异性, 主要体现在: 帕米尔高原为走滑应力机制, 显示其呈EW向扩张, 而天山山脉呈逆冲应力机制并不断隆升。帕米尔高原及其与天山山脉碰撞带两侧最优主张应力轴倾伏角和R值差异较大。6)塔西南坳陷和巴楚隆起区的走滑和逆冲应力机制不同, 且二者密度和速度差异较大, 揭示出塔里木盆地内部结构复杂的特点。
