碳球粒石 的英文怎麼說
中文拼音 [tànqiúlìdàn]
碳球粒石
英文
carbonaceous chondrite-
Even after making generous assumptions, we determined that the maximum temperature reached in carbonaceous - chondrite asteroids with a diameter of 80 kilometers or more would be only 670 degrees c, too low to cause any melting at all
即使給予很寬松的假設,我們認為直徑在80公里或以上的碳質球粒隕石小行星,達到的最高溫度只有670 ,不足以造成任何的熔化。According to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field, including lithology, size distribution, sedimenta ry structure, geochemistry and paleontology etc., the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt. it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal. the peat flat is the important paleoenviron ment for coal accumulation. the tidal channel destroys the coal bed. the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation
根據肥城煤田石炭系太原組的巖性、粒度分佈、沉積構造、地球化學及古生物等沉積特徵,將該區晚石炭世古地理劃分為碳酸鹽開闊臺地和潮坪環境,認為太原組形成於潮汐作用為主的陸表海海岸,泥炭坪是成煤的重要古地理環境,潮渠對煤層有一定的破壞作用,地殼的脈動性振蕩作用是控制沉積環境演化和聚煤作用的主要因素。Abstract : according to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field, including lithology, size distribution, sedimenta ry structure, geochemistry and paleontology etc., the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt. it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal. the peat flat is the important paleoenviron ment for coal accumulation. the tidal channel destroys the coal bed. the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation
