2 both the hanging wall and the footwail rock of ore bodies are garnet biotite schist , protoliths are alkaline volcanic rocks ( tracyh andesite ) . according to characteristics of trace elements assemblages and the setting of tectonics , these alkaline volcanic rocks were derived from the lower degree melting of metasomatic and enriched mantle ( eml ) in the initial stage of middle proterozoic epoch . they strongly enriched in large ion lithophile elements ( lile ) , such as ba 2 、礦體頂、底板圍巖(石榴石黑云母片巖、鈉長黑云母片巖等)的原巖為堿性火山巖(粗面安山巖) ,相對富集大離子親石元素ba 、 cs 、 rb 、 k 、 lree及貧zr 、 sr 、 ti 、 hf 、 hree ,為早元古代末期-中元古代早期交代富集地幔低程度部分熔融所形成的堿性火山巖。

The hanging wall of sag extended in southeast direction , with the tulage fault being the boundary fault . yinggete - bagemaode metamorphic core complex developed adjacent to northwest of chagan sag , which evolved from late jurassic to cretaceous with three - layer construction style . the kinematics mechanism of metamorphic core complex and chagan sag is a simple shear model , chagan sag extended and faulted as the metamorphic core complex rised 在查干凹陷西北側發育英格特?巴格毛德變質核雜巖帶,可能具有三層結構模式,其形成與演化時代為晚侏羅世末?白堊紀;該變質核雜巖與查干凹陷的運動學機制為統一的簡單剪切模式;在變質核雜巖隆升的同時,查干凹陷發生伸展斷陷。

Sxotf is recognized in the northern qaidam based on the analysis of structures of area . this oblique trusting fault zone with northwestern - southeastern trending consists of fault gouge , fault breccia and fault cleavage . fault hanging wall consists of sertengshan - xitieshan napple , which is distribution in dextral en echelon . fault footwall consists of youcangshan formation in neogene 本文在對賽什騰? ?錫鐵山斜沖斷裂詳細地段構造解析的基礎上,結合盆地的沉積特征、地球物理資料等對該斜沖斷裂的幾何學、運動學及形成時代進行了研究,論文著重探討了賽什騰? ?錫鐵山斜沖斷裂的地質意義。

The study area is composed of sandstone & conglomerate reservoir of alluvial fan & fan delta , which belong to sha3 lower member and sha4 upper member of lower tertiary of yong “ an town oilfield in dongying depression . the target stataum develops in the hanging wall of the synsedimentary fault in the scarp zone of dongying depression . the frequently intense movements result in the variation of sandstone and conglomerate reservoir and the evolution of the time and space of sha3 lower member and sha4 upper member in yong “ an town oilfield 研究區是東營凹陷永安鎮油田沙三下段、沙四上段的沖積扇和扇三角洲砂礫巖體,目的層發育在東營凹陷陡坡帶同生斷層的下降盤,因斷層多期強烈活動,導致永安鎮油田沙三下段、沙四上段的砂礫巖體成因類型多,時空演化變化大,在扇根一帶小層對比難度大,給油田開發帶來很大的難題,在這種背景下進行流動單元研究難度更大。

The results of 2 - d resistivity inversion of the yishui - tangtou and the liujazhuang faults indicate that electrical structures on both sides of the fault zone present obvious difference , the resistivity of the hanging wall is low and partially high , while that of the foot wall is high , and the faults are high - obliquity faults 沂水湯頭斷裂、劉家莊斷裂的二維電阻率反演結果表明,斷裂帶兩側的電性結構呈現出整體性的差異,正斷層的上盤為低阻區和局部高、低阻擾動區;而斷層下盤多為均勻的高阻區;斷層為高角度斷層。

Greenschist facies , low green schist facies and brittle shear deformation facies . the attitude of different structural element of the yagan mcc are keeping coordination . analysis of kinematics demonstrates the sse - directed shearing - off of the hanging wall relative to the footwall along the penetrative mylonitic lineation 其變形相由變質核中心到上盤巖系(由深至淺)依次為高角閃巖相? ?綠片巖相? ?低綠片巖相? ?脆性剪切變形相,顯示亞干核雜巖由中心向邊部變形層次遞減的特點。

Based on a comprehensive analysis of stability for the rock seam above hanging wall at dongxiang copper mine , effects of the stability on structures on ground surface are demonstrated , which provides science base for treating rationally relation between the structures and underground mining 通過對東鄉銅礦采空區上覆巖層穩定性的計算分析,論證其對地表建(構)筑物的影響,為合理處理這些地表建筑物和該采區地下開采的關系提供科學決策的依據。

Study on the mining method for the hanging wall ore and that under the open - pit bottom 露天掛幫礦及境界以下礦石開采方法研究

The hanging wall block is relatively little disturbed, but the ore zone beneath bears abundant evidence of tangential movements . 上盤巖塊相對地變動不大,而其下的礦石帶卻具有許多切線運動的證據。
