cataclastic adj.【地質學;地理學】碎裂的。

cataclinal

The author suggests that the three lithosphere - scale faults , lancangjiang fault , jinshanjiang - ailaoshan fault and axis fault in the middle of the basin , are the main geological structures that control the formation of basin , magmatism and metallogenic congregate district . the anticline structure with an axis of triassic strata and the related fault system within the basin , and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields . junctions of two or more faults with different orientation , interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies 認為瀾滄江斷裂、金沙江-哀牢山斷裂及盆地中軸斷裂這三條巖石圈斷裂是主要的控盆-控巖(巖漿巖)構造及礦集區尺度的控礦構造;盆地中以三疊系為軸的背斜構造及相關的斷裂系統、盆地西南緣公郎弧形構造等是礦田尺度的控礦構造;多組斷裂的交叉、層間破碎帶及地層柱中的氧化還原界面是形成礦體的有利部位。

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。

It is further indicated by the fusion of various geo - factors that the major targets include gold - bearing limonitic cataclastic rock in ningwei domain , auriferous quartz in nanhua mountain and xihua mountain domain , where the 50 - 85 strike mylonite and sulfur - bearing quartz - calcite veins of cataclastic rock is the prior ore - search targets 同時,通過多源地學因素的融合還顯示,寧衛地區找金的主攻對象以含金褐鐵礦化碎裂巖為主,南華山、西華山地區以脈型金礦為主,且重點應在50 - 85度方向糜棱巖、碎裂巖帶中尋找含硫化物的石英-方解石脈。

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 其后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于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。

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征,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。

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,但區域分布各有特點,反映出斷裂變形的空間演化。

Cataclastic texture which came from brittle deformation made the jadeite quality bed , but the mylonitic texture which resulted from ductile deformation made the jadeite quality good 在強大剪切應力和鈉質流體的共同作用下,鉻鐵礦的淡化作用是形成綠色的主要原因。
