The gold concentration areas in the northwestern Jiaodong Peninsula constituted an important gold metallogenetic region in Eastern China during the Mesozoic. The deep geological bodies＇ texture characteristic is important for exploring the resources thoroughly and understanding the metallogenic process. The detailed textures were revealed using high-resolution seismic profiles through the three major ore-controlling structures-Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone. This study aims to establish a deep structural framework of this area. Based on their formation mechanism, the fault structures developed in the area can be divided into regional and local fault structures. The structural styles are characterised by superimposing their compressional, strike-slip and extensional multi-stage activities. The crust is cut by vertical structures corresponding to a left-lateral strike-slip fault system on the surface. Nearby these structures are the arc-shape structures formed by multi-stage magma intrusions into the upper crust. Bounded by the Tancheng–Lujiang and Muping–Jimo fault zones, the current Jiaodong block, developed a series of NE-trending strike-slip fault systems, was probably formed by the assemblage of several obliquely aligned blocks. The intensive magmatism and hydrothermal activity between the blocks induced large-scale mineralisation. It provides a new angle of view for understanding the cratonic destruction and large ore-concentration formed during the Mesozoic.

In strap-down inertial navigation system (SINS), the attitude updating algorithms using angular rate have superior performance than conventional ones using angular increment for modern-day gyro whose output is angular rate. However, most of them are obtained by omitting the higher order cross product in the rotation vector differential equation, which leads to degrade the accuracy of algorithms inevitably and cannot restrain noncommutativity error in the high dynamic condition. Due to the limitation on the computer performance and modern-day gyro technology, it is impossible to increase sample numbers and update frequency infinitely for the purpose of improving the attitude accuracy. To solve this problem, the new algorithm deducted by adding the higher order cross item is proposed. Simulations are carried on under coning motion. While angular rate is used as algorithm input, the accuracy and stability of attitude computation can be improved effectively as compared with conventional ones and others using angular rate.

山东胶东地区中生代构造-岩浆事件和金矿成矿作用密切相关,其主要构造-岩浆事件包括:1220~200 Ma,扬子板块相对华北板块的南北向碰撞形成苏鲁高压-超高压变质带及同造山花岗岩与造山后高碱正长岩,属于典型的幔源型花岗岩系列;2 165~150 Ma,晚侏罗世时期形成与金矿有关的玲珑(昆嵛山)造山早期片麻状二长花岗岩组合,为过铝质花岗岩类,属胶东基底岩系的部分重熔产物。3 135~110 Ma,由壳幔混合岩浆结晶分异形成郭家岭花岗岩和伟德山花岗闪长岩。燕山期是胶东地区岩浆活动的鼎盛时期,表现为四次强烈的构造-岩浆事件,代表了燕山造山事件四个构造幕,并以挤压与伸展相互转化为特征。研究表明胶东地区中生代花岗岩具有继承性和再生性特点,采自郭家岭花岗闪长岩中的SHRIMP锆石U-Pb同位素年代学测定结果表明:锆石由核部到边部年龄值分别为2573~2194Ma、164.8~147.8和126.6~126.2Ma,显示了胶东结晶基底、玲珑花岗岩和郭家岭花岗岩形成的年代学信息,揭示了它们之间复杂的继承性和再生性,即新太古代胶东岩群、TTG岩系和古元古代荆山群、粉子山群等胶东基底岩系交代重熔形成S型玲珑花岗岩,由壳幔混合岩浆形成的郭家岭花岗岩在形成与侵位过程中重熔交代了部分玲珑花岗岩物质并侵位于玲珑花岗岩中。分析认为2573.4~2194.4 Ma是胶东结晶基底的年龄信息,164.8~147.8Ma代表了玲珑花岗岩形成的年龄信息,126.2~126.6Ma则代表了郭家岭花岗岩形成的年龄信息。这种年龄信息组合也反映了胶东地区从新太古代陆块形成、古元古代克拉通化到三叠纪华北陆块与扬子陆块碰撞至玲珑S型花岗岩形成、郭家岭壳幔混合型花岗岩形成演化的年代学记录,浓缩了胶东地区中生代岩浆起源和演化的过程,进而为诠释胶东地区深部岩浆作用过程提供了新的资料,并对后续的相关科学研究尤其是金矿的多期成矿作用提供了佐证。

玲珑花岗岩岩基东侧的招平断裂带是胶西北矿集区的主要控矿构造之一。布设于招平断裂带中段大尹格庄矿区的地震剖面,揭示了招平断裂带中段深部的结构构造特征,地震剖面显示,玲珑岩基内部有多个类似"拱弧构造"的岩浆侵入形成的弧形界面,由此推测存在2~3期的岩浆活动。剖面显示了3期构造组合样式,第1期为以招平断裂带和宋家河断裂为组合倾向SE的铲式断裂,底部似汇入统一的构造滑脱带;第2期为倾向NW的错断了招平断裂带的反倾伸展断裂;第3期为NE向延伸以花状构造为特征的走滑断裂。前两期反映构造发育处于伸展环境,第3期显示为左行走滑。招平断裂带深部延伸存在分支复合现象,形成由2个主裂面夹持的透镜状岩片。地震反射剖面数据的获得对深刻理解该区域中生代岩浆构造演化过程和深部找矿具有重要的借鉴意义。
