北衙金礦有3種成因不同的礦床：與堿性斑巖有關的銅金多金屬礦，包括與石英鈉長斑巖和石英正長斑巖有關的斑巖型銅金礦床和矽卡巖型多金屬礦床；與輝長玄武巖漿有關的鐵金礦床，包括熔漿型鐵金礦床和噴流沉積型多金屬礦床，後者又有洞穴和湖相沉積環境之分；及古砂礦，有古風化殼型砂礦、河湖相古砂礦和洞穴沉積古砂礦。Therdly because of the influence of terrain and geological structure, arenaceous resources of different regions are different in mu us. sands are mainly from riverway in northwest ; from efflorescent cretaceous sandstone on account of higher topography in the middle part of mu us ; and sands resources are intricated in southeast, mainly including riverway sands, sands blown by the wind and embedded sands under so
3 、毛烏素沙地因受地形和地質構造影響，不同區域的砂質來源情況不盡相同，西北部地區主要為河道沙；中部地區地勢較高，為白堊系基巖裸露而風化成沙；東南部地區沙質來源情況復雜，主要有：現代河道砂、風積沙、也有埋藏在現代壤土之下的出露古沙。Rock dike inserted into quartz sandstone and was then weathered and denuded to form a precipice
石英砂巖受巖脈穿插，巖脈被風化剝蝕后形成絕壁。As the increase of domestic high - rise buildings, more and more deep foundation trench supporting constructions have come into existence. among the general geographical condition of the urban district in qingdao, most of regions, which mainly consist of strong de composed rocks, are in quite good condition. except for the sandy soil and oozy soil along sea sides. but the development of rock cracks and breaking zones and unstable lamprophyre still exist, so blasting is needed during constructions of foundation trench. blasting have bad influence on the stability of slopes. moreover. the slope - liding has happened for several times, so the engineering project of foundation trench attracts more attention of people
隨著國內高層建築的發展，深基坑支護工程越來越多，綜合青島市區的地質狀況，除海邊有砂性土及淤泥軟土外，大部分地域巖土條件相對較好，多以強風化巖為主，但巖石裂隙發育，間或有斷裂帶和穩定性極差的煌斑巖穿插其中，基坑施工時需要爆破施工，對邊坡的穩定造成了不利影響，加之連續出現的幾次滑坡失穩事件，基坑支護工程越來越引起了各方面的重視。The non - structural gas reservoirs in ordos basin can be divided into 4 types, such as a reservoir of lithologic trap of sandstone lens, lithologic trap of differential diagenesis, overlying lithologic - formation trap and the reservoir related with weathering and uncomformity surface
摘要鄂爾多斯盆地非構造氣藏可分為4類：砂巖透鏡體巖性圈閉、差異成巖作用形成的巖性圈閉、上傾巖性地層圈閉、與風化殼和不整合面有關的巖性地層圈閉氣藏。In sichuan red basin, excavating cuttings in gently inclined red beds composed of sandstone and mudstone intercalations, mudstone would be indented inward by weathering, and result in a niche on the slope surface. slope, and the bearing force of the support structure must computed in design. in this paper, the overlying sandstone bed is regarded as cantiever beam, and a calculation method for the bearing force is developed, a calculation example is also given
分析了四川盆地緩傾角紅層地質結構特徵，將下覆泥巖風化形成凹巖腔后的砂巖視為懸臂巖梁，提出了一種計算泥巖風化凹進極限深度及在設計支撐柱時計算支護力的計算方法，並給出一個計算示例。( 2 ) the conception of the danxia landfonn that is a kind of the red clastic rock ( silthstone - conglomerate stone ) landfonn, derived of the of work the exogenetic and endogenetic force, characterized by red cliff, fortress, pagoda, wall, peak cluster, peak forest, etc. this article systematically summarized the evolvement, type and character
其次，界定了丹霞地貌的概念，丹霞地貌是發育在以紅色粉砂- -礫巖為主的地層中，受內力、外力（重力崩塌、風化、流水等）作用形成的地貌，具有赤壁丹崖、方山、巖堡、巖塔、巖墻、孤峰、群峰等特徵。As we know, when meeting these soils, many breakdown and danger will occur, such as the blockings, which has attracted attention of many construction personal on site. however, at present, there exist many unknown fields in blocking. firstly, the definition of blocking is not interpretative
但是，如果地層是粘粒含量較少的卵石層、砂土地層、風化巖地層，進入壓力艙的土體就很難形成這種「塑性流動狀態」 ，從而嚴重阻礙施工進程甚至造成施工事故，閉塞就是常見的一種施工障礙，已經引相關方面的重視。分享友人
