淺成大理巖
英文
epimarble-
These geomorphic units of paleogeography constitute the basic model of paleocontinent, littoral - neritic sea and carbonate plateform at that stage, and this depositional model is similar to the pattern of the east china continent and ocean, which is the result of evolution during the past long geologic age
這些古地理地貌單元構成了湖北省泥盆紀時期古陸濱淺海和碳酸鹽巖臺地的基本沉積模式，這種沉積模式與現今中國東海大陸、海洋格局基本一致，亦是經過了漫長地質歷史時期演化，而形成現今這種格局的。Sediments from this period are represented by the carboniferous marble of yuen long and ma on shan. the sandy and muddy sediments of the permain rocks of tolo harbour are of alternate marine and continental deposits
巖土其後遭淺海淹沒，沉積物不斷積聚，元朗和馬鞍山的石炭紀大理巖，便是這個時候的產物。分佈於吐露港的二疊紀砂巖和泥質巖，則屬海陸交互沉積而成。Such features can be ascribed to lower degrees of partial melting and greater melting depths. in particular, the decoupling between the lowest nag and highest tig tends to indicate residual jadeite during melting process so that na behaved as a moderately compatible element to lower the naao concentration in these rocks. this is consistent with the ree patterns in the high - ti diabases that have the highest ( gd / yb ) cn ratios than other two groups, which suggest a more important role of residual garnet in generation of the primary magmas
運用mgo = 8進行標準化，結合巖石成因理論討論了三大系列輝綠巖的形成相對深度和熔融比例，其中高ti系列的原始巖漿形成深度大，熔融比例小，源區相對最為富集易熔組分；低ti系列的熔融深度最淺，比例最大，源區相對虧損易熔組分；過渡ti系列則介於前兩大系列之間。It is directed by the 1atest theory of terrain stickin plate tectonic, and based o n petrographical series and stratum layers. from the aspects of structural analysis, stratigraphy, petrology, sedimentology, structure geology, remote sensing geology, geophysics as well as tectonics, the author put the ordos basin into a bigger and deeper studying field while using the combination of sedimentation and structure analyses, the data of outcrops around the basin and the deep drilling coring data in the middle of this basin, geochemistry analysis, seismic methods and non - seismic methods, etc. this paper discussed the relationship between the crystalline basement and the suprastructure in and surrounding the ordos basin, and also the influences of deep geology on the basin platform cover, and some new point of view and better understanding have been brought forward on the basement growth of ordos basin and it ' s platform cover
論文以板塊構造研究的最新地體拼貼理論為指導，以巖系、地層為基礎，將沉積與構造分析相結合，並以地層學、巖石學、沉積學、構造地質學、遙感地質學、地球物理學、大地構造學等多學科入手，在充分整理現有資料及前人研究的成果基礎上，利用盆地周緣野外露頭以及盆地中部分鉆井深部取芯資料、地球化學分析資料、地震、非地震等資料將鄂爾多斯盆地置於一個更大的尺度，更深的范疇，討論了鄂爾多斯盆地及其周緣地區結晶基底與淺層構造之間的關系，探討了深部地質對盆地蓋層的影響，以不與前人雷同的視角對鄂爾多斯盆地基底發育及其蓋層中存在的問題提出了新的觀點和認識。( s ) weathering and unloading action which are the two main exogenous process is active in epigenetic - surface. so, although one is different with the other, they are associated with each other closely and are cntrolled by geostress and seepage fields. in fact, weak weathered zone corresponds to weak load - off one, strong weathered zone corresponds to strong load - off one in virtue of result of this dissertation. ( 6 ) rock mass is a geologic body which is composed of rock and structural plane. and under the condition of geostress. temperature and seepage fields, correspondingly. studying weathering should pay attation to the aspects of rock, structural plane and fields. according to this. the author subdivises rockmass weathering into rock weathering and structural weathering, ulteriorly, the dissertation studies rockmass weathering from three aspects as follows : ? ock weathering : aberrance degree of mineral and physical mechanical performance of weathered rock ; ? e have already knew that weathering action damage the integrity of rock mass, but few applies it to engineering practice. the dissertation is based on trend o
本文研究結果為弱卸荷與弱風化大致對應、強卸荷與強風化大致對應； （ 6 ）巖體是由組成它的巖石與缺陷賦存於一定環境場中的地質體，據此本文將巖體風化細劃為巖石風化與結構面風化，並進而將表徵巖體風化的指標相應地歸結為三個方面來加以研究並應用於工程實踐，這就是：對于巖石風化，主要為礦物的變異程度與風化巖石的物理力學性能研究：雖已認識到風化作用破壞了巖體完整性，但將該理論應用於巖體風化分帶卻不多見，本文即從淺表部位硬性結構面間距、條數、跡長、塊度等隨遠離臨空面的變化規律來研究巖體風化分帶：不同風化、卸荷程度的巖體實際處于不同環境場中，彈性波速變化與特定環境場相對應，因而是反映巖體風化、卸荷的綜合因素。分享友人
