turbidite sequence 中文意思是什麼
turbidite sequence
解釋
濁積巖層序-
Taowan conglomerate was formed with underwater seismism at early cambrian period and consists of shattering sedimentary rock, tsunami rock, seismic turbidite and seismic volcanic rock. the shattering sedimentary rock consists of folded rock, cracked rock and autobreccia. the seismic turbidite is located in the south of luonan ductile shear zone and is called the narrow taowan conglomerate. contrarily the broad taowan conglomerate consists of shattering sedimentary rock, tsunami rock located in the north of the zone. the seismic sequence of shattering sedimentary rock - tsunami rock - seismic turbidite - seismic volcanic rock - normal sedimentary rock was first found in luonan shanxi and is rare among the reported examples about it, so it is a good example and offers power evidences to study how the southern marginal basin of huabei plate transferred to qinling orogenic belt
震濁積巖分佈於洛河韌性剪切構造帶之南，屬傳統"陶灣礫巖"范圍和涵義，即為狹義陶灣礫巖而廣義陶灣礫巖包括分佈於洛河韌性剪切構造帶之北的震積巖海嘯巖及狹義陶灣礫巖。陜西洛南地區首次發現的震積巖海嘯巖震濁積巖震火山巖正常背景沉積地震沉積序列之完整在所報導古地震作用沉積序列當中實屬罕見，為華北地塊南緣造山過程及深入了解古地震作用提供了良好地段和有力證據。 -
The main conclusions are as follows ; firstly, under the influence of three phases of episodic activities, three two - order sequences is composed of three depositional cycles and three regional unconformities ; secondly, under the control of structure activities such as fault - block activities and the influence of three - order climate cycles and source recharge, lower cretaceous can be divided into six three - order sequence ; thirdly, because fault activities is weak and fault slope is gently, fan deltas exist in steep slopes in early and later stages and subaqueous fans exist and turbidite fans exist in troughs in middle stage
主要的結論為：其一，受三期幕式活動影響，斷陷形成了3個大的沉積旋迴和3個區域不整合面，構成了下白堊統3個二級層序；其二，受斷陷內翹傾和塊斷等構造活動的控制，以及三級氣候旋迴和物源供給因素的影響，下白堊統劃分出6個三級層序；其三，在單斷斷陷湖盆中，湖泊階段的早、晚期由於凹陷邊界斷層活動較弱，斷面較緩，陡坡可以發育扇三角洲，在湖泊階段的中期主要為水下扇砂礫巖體，並在窪槽區發育濁積扇。
