帚状旋卷构造The Brush Vortex Structure
帚状旋卷构造The Brush Vortex Structure
三叠纪灰岩近东-西走向,层理清晰。在封闭体系环境中,地层受强烈构造挤压,被动作逆时针旋转(左旋),生成一组切穿地层的弧形断裂,成为帚状构造。其特征是:各断层向上端收敛,呈压性错断;向下端撒开,呈张性裂离。形成至今约2.5亿年。Triassiclimestoneisalmostorientedeastandwestwithclearbedding.Thisbrushstructurewasformedinaclosedenvironmentsystem,whereformationunderwentstrongtectoniccompressiontorotatecounterclockwise

韧性剪切变形带The Ductile Shear Zone
韧性剪切带是一类韧性断裂带。地层原生层理已被变形面理取代,并形成各种形态的次生变形褶皱,伴生石香肠和布丁构造。Theductileshearzoneisakindofductilefracturezone.Becausedirectstratificationhadbeenreplacedbydeformationfoliation,itformedvariouskindsofsecondarydeformationfolds,alongwithboudinage.

平卧尖棱紧闭褶皱The Recumbent Closed Angular Fold
三叠纪薄板状灰岩在强烈逆冲推覆作用下,形成平卧紧闭尖棱褶皱。褶皱枢纽呈水平或近水平状倒转平卧,转折端尖棱状,两翼近对称。三叠纪薄板状灰岩距今2.5亿至2.03亿年。Triassiclaminatedlimestoneformedrecumbentclosedangularfoldundertheactionofastrongthrustnappe.Foldhingeappeatobehorizontalornearhorizontalinvertedrecumbent,angularshapeturnend,andtwowingsarenearlysymmetric.Triassiclame

鳄鱼潭The Crocodile Pond
三叠纪灰岩出现一正断层,发育断层角砾岩。断层带伸入河中,生成一碳酸盐岩溶溶洞,人称鳄鱼潭。早三叠世是三叠纪三个世之首,距今约2.5亿年。Triassiclimestoneariseanormalfault,formingfaultbreccia.Faultzonestuckintoriverandgeneratedacarbonatekatcave,soitwascalledascrocodilepond.TheEarlyTriassicisthefitofthethreeTriassicages,about250millionyeaago.

韧性剪切带与不协调褶皱The Ductile Shear Zone and Disharmonic Fold
露头级韧性剪切带挟持于块状砂质灰岩(左侧)与薄板状灰岩(右侧)之间。剪切带中,地层变形强烈,原生层理揉皱形成平卧和倒转褶皱,并成为变形带中的集合块状旋转体。岩层和方解石脉被拉断,成为石香肠或布丁构造。韧性剪切带两侧地层变形较微弱,呈舒缓褶曲。总体构成不协调褶皱景观。Ductileshearzonesandwichedbetweenmassivesandylimestone(onleft)andlaminatedlimestone(onright).Inshearzonethestratumproducedstrongdeformation;nativebeddingformedtherecum

三叠纪薄板状灰岩箱形褶皱The Box Fold of Laminated Limestone from Triassic
箱型褶皱是官珠沟常见褶皱形态之一。箱状褶皱是强应力下形成的地层褶皱变形。主要特征是:顶部平直,两翼近于平行的箱形构造。三叠纪薄板状灰岩箱形褶皱距今约2.5亿年至2.03亿年。BoxfoldisoneofthecommonshapesinGuanEvalley.Boxfoldisstratafolddeformationformedunderstrongstresswhichischaracterizedbyfollowing:thetopisstraight;twowingsareboxstructureclosetotheline.Triassictabularlimestoneboxfol
