cataclastic rocks 解釋
壓碎巖
  1. Three stages of deformation can be distinguished from the cataclastic superposition of matrices that infilled the microcracks in cataclastic rocks, and two phas es of paleotectonic stress field from the typical conjugated shear joints by stereograms illustrating

    構造巖中膠結物和微裂隙充填脈反映了巖石碎裂變形的三次疊加。斷裂變形帶內發育兩期典型的共軛剪節理,但區域分佈各有特點,反映出斷裂變形的空間演化。
  2. Zijingguan fault zone is characterized with cataclasite series of tectonic rocks and joints alongside the deformational zone, and sometimes with uniclinal flexure or folds. the intensity of deformation increases from the sides to the center of the fault in the section, which appears from joints to cataclastic rocks

    紫荊關斷裂帶兩主斷裂變形帶以碎裂巖系列構造巖和節理帶組合為特徵,局部出現撓曲和褶皺,由兩盤至斷裂中心變形強度增大,一般由節理帶過渡為碎裂巖帶。
  3. The fault controlled the magmatism and metallization relevant to the contact zone, and deformed successively and produced cataclastic rocks and two sets of joints ; the second stage was from late cretaceous to eocene. the fault zone deformed right - laterally under ne - sw striking transtention, and new joints zone was produced at the end of the two main faults because of local stress concentration. the fault produced inchoative cataclastic rocks, and two sets of typical joints in plutons ; the third stage of deformation was relatively faint and only a little of microcracks was produced and infilled with vei ns in the deformed rocks, which was during the himalayan movement

    其後的繼承性活動在斷裂帶內形成碎裂程度最強達到碎裂巖的碎裂巖系列構造巖,變形帶兩側發育兩組典型的共軛剪節理;第二次在晚白堊世?始新世,斷裂在北東?南西向近水平擠壓作用下右行張扭性活動,斷裂帶兩主斷裂在斜列重疊的端部由於局部應力集中進一步擴展形成節理帶,而斷裂在巖體區也發育兩組典型的共軛剪節理,斷裂內形成初碎裂巖為主的構造巖;第三次是喜山期以西側抬升、東側下降的強烈升降為主的活動,在基巖中,主斷層兩側圍巖出現微破裂。
  4. The cataclastic rocks appeared in the fault zone include structural lenticles, fault breccias, protocataclasite and cataclasite. the microscopical cataclastic deformation mechanisms involved are microcracking, frictional sliding and pressure - solution, but there might have had ductile deformation relating to dislocation sliding in feldspar and quartz of the plutons

    斷裂帶內碎裂巖系列構造巖主要是碎裂化巖石(包括構造透鏡體和構造角礫巖) 、初碎裂巖和碎裂巖,顯微變形機制主要有破裂作用、摩擦滑動和壓溶作用。
