tidal flat deposits
解釋
潮浦沉積-
In this field observation we also find an important fact that, even during storm surge period, high tidal flat can still be in sedimentation in some place, no erosion occurred. to tell the typhoon storm surges from cold wave storm surges, 12 monthly sedimentary samples are collected from the modern tidal flat surface at dafeng, jiangsu. palynological analysis of these samples indicates that the seasonal palynological features of the tidal flat sediment are very obvious and some palynological indexes, such as taxon percentage of arboreal, herbaceous pollen and spore, are good indicators to tell the seasonality of the tidal flat deposits
為區分風暴潮沉積是由臺風引致還是由寒流或冷鋒引致，對長期處于淤積狀態的江蘇中部大豐縣斗龍港附近潮灘，採集了一年中每月小潮期間灘面表層泥樣，並在啟東茅家港灘面分別採集了6月、 9月與12月的表層泥樣，在實驗室中，對這些樣品進行孢粉等分析，認為在以粉砂、泥為主的潮灘沉積中，孢粉種類百分比，尤其是木本種類占孢粉總種類的百分比是判別季節性潮灘的重要指標，通過啟東茅家港工程建設區淤積狀況的觀測記錄對這一判別指標進行了驗證。 -
Based on the direction of sources and the ratios of sandstone to formation of sedimentary rocks, together with the sedimentary structures and textures, paleocurrent direction and the characteristics of paleontology, etc., the planimetric maps of sedimentary facies of each stages in the studied area are compiled in order to recognized the extension of dominant facies and the evlotionary history of sedimentary environment, hi the stage of benxi and taiyuan, lagoon - tidal flat sediments are widespread in the area, and the deposits of estuary, lagoon and small delta in the northwest margin of ordos
以物源方向和沉積巖砂地比值為基礎，結合沉積結構構造、古水流方向及古生物特徵等，編制了研究區各期次的沉積相平面圖，以識別優勢相展布和沉積環境演化。本溪期和太原期研究區瀉湖?潮坪沉積分佈廣泛，西北緣發育河口灣、瀉湖及小型三角洲沉積。 -
( 2 ) based on the two important sections of yanshiping and yicangma, a study is conducted on the sedimentary features and facies of middle - upper jurassic series, it is suggested that quemo formation is river - delta facies deposit, buqu formation is chiefly carbonate ramp facies deposit, xiali formation is delta - tidal flat facies deposit, ? suowa formation is mixed shelf - lagoonal facies deposits and xueshan formation is river - delta facies deposit
（ 2 ）以雁石坪和依倉瑪兩條重點剖面為基礎，開展了中?上侏羅統沉積特徵、沉積相等方面研究，認為研究區雀莫錯組為河流?三角洲相沉積，布曲組以碳酸鹽緩坡相沉積為主，夏里組為三角洲?潮坪相沉積，索瓦組為混積陸棚?瀉湖相沉積，雪山組為河流?三角洲相沉積。
