In middle and late periods of the early permian, the pre - caspian areas rose successively, the climate became dry, and the environment turned to be supratidal zone ( evaporitic environment ), resulting in the spread sedimentation of salts and the formation of the salt sediment group ( the upper part of the lower permian ) which consists mainly of halite and anhydrite
早二疊世中後期由於持續構造抬升，盆地氣候變得乾旱，海水變淺，潮上帶蒸發環境發育，以致這一時期廣泛發育鹽類沉積，形成含鹽層系，主要由鹽巖和硬石膏層構成，並形成許多大小不等的鹽丘構造。The sahara ' s topographical features include shallow basins, large oasis depressions, serirs or regs ( gravel - covered plains ), plateaus, mountains, sand sheets, dunes and sand seas ( ergs )
撒哈拉沙漠地形特點包括：淺的盆地、大的蕭條的綠洲、砂礫性沙漠或礫質沙漠（碎石覆蓋的平原） 、高原、沙席（小沙原） ，沙丘和沙海（砂質沙漠） 。With an area of 5300 km2, dongpu depression is located in the southwest of lin - qing depression, bohaiwan basin, bounded with lu - xi uplift by lan - liao fault in the east, with nei - huang uplift by chang - yuan fault in the west, with lan - kao heave by the north feng - qiu fault in the south, with xin country depression by ma - ling fault in the north, while spreading along nne defection, taking on the forms of being wide in the south, and narrow in the north. it is a rift fault depression basin with the characteristics of striking, with the basement being the paleozoic and mesozoic, and the capping beds being the cenozoic
東濮凹陷位於渤海灣盆地臨清坳陷西南端，東側以蘭聊斷裂為界與魯西隆起為鄰，西側以長垣斷裂為界與內黃隆起相接，南以封丘北斷層為界與與蘭考凸起相鄰，北以馬陵斷層為界與與莘縣凹陷相望，是以古?中生界為基底，以新生界為蓋層，古近紀形成的拉分走滑?裂谷型箕狀斷陷盆地。Meanwhile the qinlin mountain range also forms the border between yellow river valley in the north and the yangzhi river valley in the south, hence the region serves as a sole bridge between the qin ' s area ( representing northern china region ) and shu ' s area ( representing southern china region ), and from a geographical view, southern shaanxi province works as a channel for the remote areas in huna and hubei provinces
正是由於陜南地區明顯地具有南北過渡、東西交匯的地理特徵，陜南地區無論是自然環境，還是經濟、社會、文化，都具有一定的典型性。所以，陜南農業經濟的開發，既可以代表南方亞熱帶稻作農業和北方暖溫帶旱作農業兩種不同的開發模式；又包涵平原、盆地、丘陵、山地四種主要地貌形態的開發特徵。Depending on how the ground surface is denuded, the feature of the current crustal stress field and rock stress environment can be calculated analyzing the result in this paper : by analyzing the recovering feature of the elastic deformation of the rockmass in unload - stage under various pressures, it has been found there is close relationship between the recovering degree of the elastic deformation of the rockmass and the unloading degree of the pressure the direction of the major principal stress in the crustal stress field is not consistent with the direction of the crushing stress regional tectonics borne during the last tectonic movement. the evolving degree of the regional geomorphology evidently affects the current crustal stress field, which changes from the self - weight stress field to the horizontal stress field, with the changing of the eroding degree of the regional geomorphology ranging from valley area to hilly country to flat country. in valley area, where there is two stress belts, the bankslope s tress belt and the self - weight stress belt within the mountain. the direction of the major principal stress is nearly parallel to the ground surface and inclines towards the valley in the bankslope stress belt. it is nearly vertical in the self - weight stress belt
通過本文的研究成果，根據區域性地貌的演化特徵，我們可以大致地對現今地應力場進行判斷：在分級卸荷條件下，巖體中彈性變形的恢復具有明顯的規律性，這種規律對于研究地應力場的演變是有幫助的；地應力場中最大主應力方向與區域構造形跡在最近的構造運動中所受區域性擠壓應力的方向無明顯的對應性；區域性地貌形態的演化程度對現今地應力場的特徵具明顯的影響，隨著區域性地貌侵蝕程度由峽谷區、丘陵區、平原區的變化，現今地應力場特徵由自重應力場、水平應力場為主含少量自重應力場特徵向水平應力場的規律變化；在峽谷區，山體中具有兩個應力帶：自重應力帶和卸荷應力帶，最大主應力方向在卸荷應力帶中近平行於坡面並傾向于河谷、在自重應力帶中近於直立；根據原始地面遭剝蝕的程度，可以大致地估算最大主應力和中間主應力的量值和方向；在丘陵區和平原區，最大主應力的方向近於水平，並與附近區域性侵蝕盆地和河流的展布方向基本平行，根據原始地面遭剝蝕的程度，可以大致估算其最大主應力的量值；根據區域性地貌形態的特徵來分析工程區的現今地應力場特徵，並進而大致了解巖石的應力環境，這種分析方法得出的結論與許多實際的地應力測試成果基本一致，對于大型水電工程地下廠房和壓力隧洞的設計是有所幫助的。The topography is hilly in the main, with big and small rivers crisscrossing. there was certain ratio of valley basins
韶關市地形以山地丘陵為主，大小河流密布，河谷盆地也有相當比重。分享友人
