1 引 言
远离板块碰撞带的天山是典型的陆内造山带.如何理解天山陆内造山机制与浅-深部动力学过程一直是地学家关心和讨论的主要问题[1-15].
关于天山隆升的机制,有影响的论点是印度板块的远距离碰撞效应[7,12].晚新生代以来,印度板块与欧亚大陆的汇聚作用和持续碰撞使中亚内陆沿天山、昆仑山、阿尔金山发生变形[7,13].现今 GPS观测结果[14-15],塔里木盆地整体上对天山褶皱带形成正向挤压,刚性的塔里木盆地内部基本不变形[14],向北传递来自印度板块的推挤应力[15].
也有学者根据天山山前万米的新生界沉积记录和频发的地震活动[16-17],认为塔里木地块与哈萨克斯坦板块的向天山下的汇聚、俯冲可能仍在继续,南天山前可能隐伏着巨大的大陆板块俯冲带[18],塔里木板块沿着这个巨型俯冲带深深地俯冲到天山之下,导致现今天山的隆起.俄罗斯学者解释最近的地震观测资料时,仍维持这种认识[19].
数条穿过塔里木盆地与天山造山带南缘的深地震测深剖面[20-22],均揭示了刚性的塔里木盆地具有稳定较硬的基底,地壳平均速度较高(6.5km/s),地壳厚度45km,向北进入天山造山带,地壳显示了软弱的特征,平均速度为6.2km/s,地壳加厚到50~55km[20,23].接收函数的结果显示,南天山的平均地壳厚度为52km[24].由宽角地震反射、重力数据反演和面波层析综合计算所获得的Moho深度图[25]揭示出,Moho面深度由塔里木板块下的48km加深至南天山下的60km.其它一些天山及邻区主动源和天然地震的观测的成果,揭示了该地区岩石圈及地幔过渡带较为复杂的行为特征[26-29].
近年来,国内外学者对南天山的浅部地壳,即新生代构造变形开展了不同程 度的研究[13,30-33],这些研究为认识天山与塔里木盆地的构造变形和演化提供了非常重要的依据.在解剖盆山构造关系研究中,前人一般是利用石油地震剖面解释来研究盆岭耦合关系的构造样式,并建立构造模式[34].这些剖面通常只记录到双程走时(TWT)6s,最多9s[35],这对研究并刻画盆地的基底是足够的,但是这些资料无法提供盆地下,尤其是盆山结合部的浅-深结构信息及其联系.
深地震反射剖面已被国际地学界公认为揭示地壳精细结构的有效手段[36-42].探测塔里木块体北缘与南天山岩石圈尺度的接触关系,无疑将提升对该区新生代以来的构造形变特征、几何结构的认识,将促进板内造山动力学研究的发展.本文展示一条布设在西南天山与塔里木盆地结合部位的深地震反射时间剖面,打开一扇剖析该区浅-深构造关系的窗口.本文主要介绍Moho界面以上,地壳尺度内的浅-深反射特征的联系,关于Moho界面以下岩石圈地幔的反射构造,作者将另文发表.
2 区域地质构造概况和深地震反射剖面位置
位于南天山与塔里木盆地过渡区的南天山褶皱冲断带,发育多排东西走向的逆冲断层和相关褶皱[4,6,43],各排构造变形特征及年代学分析也有相关报道[34,44],逆冲断层由北向南扩展[45],断层和褶皱的形成时代自北向南逐渐变新[6].研究区位于南天山冲断褶皱带西段、西昆仑造山带西部帕米尔构造结(外帕米尔带)和塔里木盆地西北部(喀什凹陷)等构造单元的交汇部位(图1).
作为塔里木盆地的一个次级构造单元,喀什北缘地区具有复杂的地质结构和丰富的油气资源,将是研究盆地变形和盆山耦合关系的典型区域.其构造变动既受天山褶皱系活动的控制,又与塔里木盆地构造活动相关,造就了其复杂而又独特的构造特征.现今南天山冲断带位于南天山造山带和塔里木盆地的过渡地带,基底性质属于塔里木古大陆边缘的一部分,在南天山长期复杂的地质构造演化过程中,逐渐卷入造山作用,成为现今南天山山脉的一部分[35].
为了研究南天山与塔北前陆盆地主要冲断构造、断裂展布和浅深构造关系,进而探讨油气远景,2007年夏季,中国地质科学院地质研究所联合中石化勘探公司和美国南卡罗莱纳大学在喀什东布置一条横过塔里木盆地西北缘与天山南缘的地震反射测线,剖面大致沿76°E展布,自阿图什南,向北至中国与吉尔吉斯边境附近,大致沿阿图什市向西北至乌恰县铁列克的公路进行.剖面位置见图1,地震测线自南向北分别穿过喀什背斜带、阿图什背斜带、柯克塔木、塔什皮萨克背斜带和木兹杜克背斜带;塔什皮萨克断裂(F1)和麦丹断裂(F2).
3 数据采集和处理
图1 深地震反射剖面位置图黑线为深地震反射剖面共中心点(黄色数字)位置,红线为断层.Fig.1 Location map of deep seismic reflection profileBlack line is disruptions of common midpoint(yellow number),red line is the fault.
地震测线采用弯线施工,全长121km,其中炮间距250m,检波点距50m,采用正常小炮(40kg)、中炮(80kg)和大炮(200kg以上)三种药量尺度的深井(井深范围20~36m)激发和长排列接收进行数据采集,共采集474炮,其中小炮347个,中炮115个,大炮4个.具体采集参数见表1.
表1 深地震反射采集参数Table 1 Data acquisition parameters of deep seismic reflection
沿地震测线由盆地区进入山区,最高海拔高程2887m,最低海拔高程1228m.浅层折射面不连续,低、降速层厚度变化较大,山地区低速层厚度大,一般在20~31m之间,存在降速层,高速层速度达2500~3600m/s,盆地区无降速层,低速层厚度在5~9m,高速层速度在1600m/s左右.单炮记录总体较好,浅、中、深反射波组较为齐全,能量较强,连续性较好,莫霍反射出现在17s(TWT,双程走时,下同)左右.
在南天山—塔里木盆地盆山结合带,地形起伏较大,表层、地下地质结构非常复杂,静校正问题、弯线面元的离散度等因素影响叠加效果.
采用组合静校正方法以解决盆山结合带近地表静校正问题[46];采用地表一致性振幅补偿和振幅一致性反褶积解决了振幅、频率一致性问题[47].采用多域组合去噪技术有效地压制了噪声,采用多道叠加技术对远偏移距多次波进行压制,应用预测反褶积技术消弱部分多次波,在此基础上,对近偏移距多次波和层间多次波适当采用了近道切除压制技术来消除部分噪声,并利用F-K倾角滤波技术,通过校正和信噪分离滤除多次波(图2),提高了资料信噪比.
4 盆山结合带浅-深构造格架特征
西南天山—塔里木盆地间的盆山结合带深地震反射时间剖面成果(图3,CMP间距25m),揭示出塔里木盆地与西南天山结合地带的地壳精细结构,从浅部到深部反射波组强,层位清晰,接触关系明显.通过西南天山与塔里木盆地西北缘的盆山结合带的探测,显示出塔里木盆地的浅部变形特征明显受到深部结构的控制.这种结构关系,有助于进一步认识塔里木盆地与天山造山带结合部位地壳形变特征及盆地内油气盖层特征.
4.1 稳定基底与盖层变形
地震反射剖面南段显示塔里木盆地北缘6.5s强水平反射层,代表塔里木盆地北缘基底埋深约为12km (按4km/s的上地壳平均速度[17])(图4).沉积物层5.1s,约10km处观察到另一强水平反射界面,解释其为沉积物盖层底部的主滑脱层(图4).盆地北侧广泛分布的强水平反射揭露出塔里木盆地北缘至阿图什背斜基底稳定,无断裂活动.地震反射剖面中段,基底和滑脱层反射层上隆并向北延续被断层(F2)截断,断层切穿沉积物和基底延伸到下地壳(图4).由此我们解释喀什背斜为断层滑脱褶皱,阿图什背斜为断层相关褶皱.受南北挤压影响,沉积物沿滑脱层向上隆起.地震反射剖面北段南天山一侧,沉积物层和基底反射波阻不连续,断裂活动明显,表明天山构造活动强烈.
地震剖面证实塔北前陆盆地的构造变形及其演化与南天山造山带的发育密切相关[48].靠近天山,塔里木盆地北缘的新生代沉积层受主滑脱断裂活动影响产生隆起,形成褶皱.自南向北,基底埋深变大,变形加强.至南天山,断裂活动最为明显.虽然盆山结合部位浅层地震波组不很清楚,但是两侧波组差异较大.剖面北侧西南天山向盆地发育一系列向南的逆冲构造,其变形深度席卷了整个沉积盖层,波及下地壳.
图2 盆地内400kg大炮记录Fig.2 400kg shot gather in basin
4.2 Moho反射
陆内造山所构建的区域性盆山格局及其构造耦合是汇聚单元在岩石圈尺度上进行的过程,造山带及山前构造带同受深部构造的控制,浅部的构造变形与深部构造有着复杂而有机的联系[49].整条剖面上都得到了较清楚的莫霍面反射.塔里木盆地莫霍面较平坦,时间深度约17s.西南天山的莫霍面略深,在18s左右.两者在盆山结合部位下存在莫霍面错断(图4).
4.3 盆山结合部浅-深部结构关系
剖面显示出塔里木盆地北缘发育主滑脱构造与南天山山脉发育的南倾隐伏逆冲断层在盆山结合带形成断层相关褶皱.由南向北至南天山断裂活动加强,地层错断明显(图4).南天山底部莫霍面也发生错断,印证新生代天山隆起过程中构造活动强烈,反映出新生代中国西部陆-陆汇聚的一种深部过程及浅部响应.
5 讨论与结论
南天山—塔里木盆地盆山结合带深地震反射剖面反映了沉积地层、山前断裂、逆冲构造、下地壳倾斜反射、莫霍面起伏等多方面丰富的信息,揭露了盆山结合带地壳尺度内的浅深精细结构.
(1)地震剖面南部揭示出塔里木盆地西南缘沉积盖层厚度可达约12km,并且具有稳定的结晶基底.沉积物层内发育主滑脱层.巨厚的沉积和稳定的基底在整条剖面都可以追逐,为油气生成与成藏提供了物质基础.类比同一构造区阿克1井的钻井资料,喀什背斜南翼中生界白垩系地层具有油气远景.
(2)喀什背斜和阿图什背斜为断层相关褶皱.木兹杜克背斜、塔什皮萨克背斜、柯克塔木—阿图什背斜及喀什背斜之间分别发育上地壳尺度的向北倾斜的断裂(断裂F1-F2)和向南倾斜的隐伏断裂(F3-F4).
(3)上地壳一系列南向的逆冲构造反映了西南天山向盆地的仰冲作用席卷了整个沉积盖层,并且越向天山内部,逆冲变形作用席卷的深度越深.
(4)时间剖面上可以追踪到较为连续的 Moho反射,从南向北Moho面反射时间从17.4s变化为17.9s,在盆山结合处略有上挠至17s,结合该区域的测深结果[20,26],总体上南天山 Moho面埋深要比塔里木板块深约6~8km.
南天山—塔里木盆地盆山结合带具有极其复杂的地质背景,需要不断探索反射地震工作的方法和思路,在盆山结合带的核心部位加大探测工作量,以获得更优质的深反射地震数据,进而更准确地为推测油气远景规模服务.
