碎裂體系 的英文怎麼說
中文拼音 [suìliètǐxì]
碎裂體系
英文
fragmentary system-
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。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。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。
