中文拼音 [shǐbáiècéng]
始白堊層
英文
eocretaceous-
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。Based on the analyses of structural features, volcanic activities, sequence construction and so on, it is believed that liaohe basin has experienced the period of dextral transtensional stress field in late jurassic - early cretaceous, middle and late paleocene, late eocene, miocene, and also the period of sinistral compresso - shear stress field in late cretaceous, early paleocene, early and middle eocene, oligocene, pliocene
對構造現象、火山活動、層序充填型式等多種實際資料的分析表明:遼河盆地經歷了侏羅紀末白堊紀早期、古新世中後期、始新世中後期、中新世等右旋張扭應力場作用階段,以及白堊紀晚期、古新世初期、始新世早中期、漸新世、上新世以來等左旋壓旋應力場作用階段。It seems that submarine magmatism and hydrothermal activity provided abundant ore - forming material for partly strata of mogaganri and yanshiping formations during the extension of bangongcuo - nujian marginal sea in early - middle jurassic. therefore parts of jurassic mogaganri and yanshiping formations became original source of ore - forming material. in later early jurassic, the collision and collage between qiangtang block and nianqing - tanggula block made favorable conditions in geological structure, magma and ore - forming fluids for the formation of gold deposits
在早-中侏羅世班公錯?怒江邊緣海擴張過程中,海底巖漿及其熱液作用,為侏羅系木嘎崗日群和雁石坪群部分層位提供了大量的礦源,使其成為初始礦源層;早白堊世晚期,羌塘地塊和岡底斯?念青唐古拉地塊碰撞拼貼,造成了有利的構造條件、巖漿條件、成礦流體條件,形成礦床。The swede - field in which she and her companion were set hacking was a stretch of a hundred odd acres, in one patch, on the highest ground of the farm, rising above stony lanchets or lynchets - the outcrop of siliceous veins in the chalk formation, composed of myriads of loose white flints in bulbous, cusped, and phallic shapes
苔絲和她的同伴開始動手挖瑞典蘿卜的那塊田地,是一百多畝的一大片,也是那個農場上最高的一塊,突出在白堊質地層或者砂石混雜的地面上它的外層是白堊質巖層中硅質礦床形成的,裏面混合著無數的白色燧石,有的像球莖,有的像人的牙,有的像人的生殖器。分享友人
