The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.

本文重点解剖了位于地震破裂带南西段的汶川映秀牛圈沟滑坡-碎屑流、位于地震破裂带中段的北川城西滑坡和位于地震破裂带北东段青川东河口滑坡-碎屑流3个典型实例,认为具有如下特征:1)岩性条件:母岩遭受长期构造动力作用,呈碎裂岩体,后期被强烈风化,岩体极为破碎;(2)抛掷效应:位于汶川地震主断裂带或附近,垂直加速度大于水平加速度,强地面运动持时长,岩体发生振胀和抛掷;3)碰撞效应:上部滑坡体发生高位剪出和高位撞击,致使岩体碎屑化;(4)铲刮效应:撞击作用导致下部山体被铲刮,形成次级滑坡,为碎屑流体提供了足够展翼和抛洒物源体积;5)气垫效应:碎屑化岩体快速抛掷导致下部沟谷空气迅速谷状圈闭和向下紊流,形成气垫效应,或者,在下部地形开阔地带压缩空气呈层流状态致使滑体凌空飞行。

The rocks were probably situated in the followup obduction of split upper crust cover of the Yangtze Plate onto the North China Plate in or after the subduction of the Yangtze Plates continental materials towards the North China Plate,or were placed by southward thrusting when ultrahighpressure metamorphic rocks underpinned.

通过露头的构造地质分析,推断本套地层是在扬子板块陆壳物质向华北板块下深俯冲过程期间或其后扬子板块陆壳上部盖层继续向华北板块仰冲就位的,在超高压变质岩折返时经历了由北向南的逆冲。

Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.

矿体产于红岩寺—黑山复式向斜南翼金井河—胡家沟次级背斜南翼近轴部断裂中,赋矿岩石为泥盆系青石垭组中上部白云质岩,其空间展布明显受背斜陡倾南翼近轴部的层间断裂-裂隙带构造控制,矿石主要有团块状和网脉状,其后生成矿现象非常明显。
