簡介:摘要對(duì)陜甘寧盆地、塔里木盆地以及長江三角洲的部分沉積地質(zhì)學(xué)問題進(jìn)行了研究。主要內(nèi)容包括陜甘寧盆地新構(gòu)造活動(dòng)與地貌,塔里木盆地東部地區(qū)形變構(gòu)造系統(tǒng)及其構(gòu)造組合樣式,陜甘寧、塔里木盆地中上奧陶統(tǒng)薄互層泥、灰?guī)r沉積特征,趙老峪、平?jīng)鼋M遺跡化石與沉積環(huán)境,長江三角洲晚第四紀(jì)地層生物成因的原生沉積構(gòu)造以及與地層結(jié)構(gòu)相關(guān)的環(huán)境地質(zhì)災(zāi)害等。主要認(rèn)識(shí)如下1陜甘寧盆地內(nèi)部新構(gòu)造活動(dòng)較為明顯,控制著現(xiàn)代地貌、地形及水系的發(fā)育。1控制主千河流及其支流的走向呈現(xiàn)出明顯的鋸齒狀,鋸齒方位主要為北北東、北北西和北西向2盆地南部黃土高原植被、含水性及地貌呈菱形塊狀分布,菱形塊狀邊界主要呈北北西和北東走向3盆地北部哪爾多斯高原內(nèi)部湖沼及鹽沼的展布主要為北西向。毛烏素沙漠的巨大沙隴呈北西走向。2在塔里木東部地區(qū),形變作用力主要來自于天山造山帶的擠壓作用以及阿爾金斷裂帶的走滑作用。從演化序列上看,古生界的變形構(gòu)造樣式多屬墓底卷入型。中生界的變形構(gòu)造樣式多屬蓋層滑脫型新生界變形作用微弱,僅在盆地邊緣發(fā)育走滑以及逆沖構(gòu)造從平面分布上看,驀底卷入型在盆緣及盆地內(nèi)部都有發(fā)育,而蓋層滑脫型主要發(fā)育于盆地邊緣帶。3中上奧陶統(tǒng)平?jīng)鼋M、趙老峪組、克里摩里組、公烏素組、烏拉力克組、斯家溝組、其浪組、斜稼組、坎嶺組等沉積地層之中都發(fā)育典型的泥、灰?guī)r薄互層沉積MLML的重要特征是發(fā)育多級(jí)別的旋回。其中發(fā)育有濁流、火山、陸架崩塌、風(fēng)暴等多種事件沉積,以及豐富的形態(tài)較為完整的屬于ZOOPHYCOSNEREITES或者兩者混合相的遺跡化石組合。首次在趙老峪組發(fā)現(xiàn)風(fēng)暴沉積。4在趙老峪組中共發(fā)現(xiàn)屬于NEREIT“遺跡相的遺跡化石17屬25種,其中15屬為本地區(qū)新發(fā)現(xiàn)。遺跡組合反映趙老峪組主體形成于濱外最天風(fēng)攀浪蕃面以下海水較深和安靜的沉積環(huán)境之中。在平?jīng)鼋M中首次發(fā)現(xiàn)屬子典型的深水NEREITES相遺跡化石4屬3種,1未定種。其中MEGAGRAPTONSQODICTYON形成于事件前,PALEOLITESSABULARIA形成于事件后,該遺跡組合說明平?jīng)鼋M黑色筆石頁巖中發(fā)育有濁流事件沉積。其中發(fā)育SABULARIA一為UAMODICTYON組合遺跡化石的薄層灰?guī)r多是由臺(tái)地相鈣質(zhì)碎屑物質(zhì)的突然輸入形成,即事件沉積。5在長江三角洲晚第四紀(jì)地層連續(xù)取芯鉆探工作中,通過選用大功率鉆機(jī)以及活動(dòng)頭雙套取土器,采用無泵干鉆工藝,使得取芯率達(dá)到90以上,且?guī)r芯內(nèi)部原生沉積層理清晰,取芯擾動(dòng)小。在巖芯中,發(fā)育生物遺跡、生物擾動(dòng)及植物根痕跡等原生生物成因的沉積栩造。關(guān)長詞沉積地質(zhì)學(xué),遺跡化石,塔里木盆地,俠甘寧盆地,長江三角洲NUJ呂陜甘寧盆地、塔里木盆地以及長江三角洲沉積地質(zhì)學(xué)研究是我博士后期間部分研究工作的初步總結(jié)。之所以選擇如此一個(gè)又大又泛的題目,緣起兩點(diǎn),一是繼續(xù)博士期間的工作,二是在古今結(jié)合的基礎(chǔ)上,從沉積過程到地層記錄,從地層記錄返回到過程,力求有所創(chuàng)新。第一章研究陜甘寧盆地網(wǎng)狀斷裂與地貌和水系發(fā)育之間的關(guān)系,試圖闡明構(gòu)造穩(wěn)定區(qū)域內(nèi)部弱構(gòu)造變動(dòng)帶的特點(diǎn)及其對(duì)沉積作用的控制作用。第二章研究塔里木盆地東部地區(qū)的構(gòu)造系統(tǒng),討論不同深度的斷裂構(gòu)造,以及薄皮構(gòu)造和厚皮構(gòu)造展布的特征。沉積地質(zhì)學(xué)研究如果不與構(gòu)造作用結(jié)合起來,盆地沉積演化、層序發(fā)育等研究就難以深入。顯然。掌握良好的構(gòu)造地質(zhì)學(xué)基礎(chǔ),對(duì)我今后沉積地質(zhì)學(xué)研究是極為有益的。第三章研究了我國西北地區(qū)中上奧陶統(tǒng)發(fā)育的典型泥、灰?guī)r薄互層沉積MLML的重要特征是背景沉積穩(wěn)定,其中發(fā)育有濁流、火山、崩塌、風(fēng)暴等多種事件沉積。從豐富的沉積記錄中,可望闡明多種海洋事件沉積的相互關(guān)系,這對(duì)加深沉積過程的了解,建立災(zāi)害預(yù)報(bào)模型都是十分有益的。第四章研究了中上奧陶統(tǒng)趙老峪組豐富的遺跡化石及其環(huán)境意義,首次報(bào)道了平?jīng)鼋M發(fā)育的NEREITES相遺跡化石組合。生物成因的原生沉積構(gòu)造具有原生性、不混生性、對(duì)沉積環(huán)境反映敏感等優(yōu)點(diǎn),將會(huì)在沉積過程的研究中發(fā)揮重要作用。第五章探討了長江三角洲晚第四紀(jì)地層連續(xù)取芯鉆探技術(shù)。對(duì)巖芯中發(fā)育的生物遺跡、生物擾動(dòng)及植物根痕跡等生物成因的原生沉積構(gòu)造進(jìn)行了初步研究。此外,對(duì)長江三角洲地區(qū)與沉積地層結(jié)構(gòu)相關(guān)的環(huán)境地質(zhì)災(zāi)害問題也進(jìn)行了初步探討。以上工作并不是雜亂無章和奄無關(guān)聯(lián)的,都是在同一個(gè)主題一一沉積地質(zhì)學(xué)之下,貫穿所有的工作之中。應(yīng)當(dāng)指出,對(duì)于陜甘寧盆地、塔里木盆地以及長江三角洲的相關(guān)沉積地質(zhì)學(xué)研究這一綜合性很強(qiáng)的重大命題來說,本文只是在某幾個(gè)方面進(jìn)行了論證,有的僅僅提出了工作模式或假說,論證尚未深入,難免有不妥之處,懇請(qǐng)?jiān)u閱者批評(píng)指正。以利于今后工作更加深入的開展。在同濟(jì)大學(xué)良好的科研條件下,力圖有所創(chuàng)新,是我一直堅(jiān)持和努力的,也應(yīng)該是一個(gè)年青地質(zhì)工作者所必備的素質(zhì)。
