神奇喀斯特 Magic karst 1015次播放 简介>>
(1)什么是喀斯特?What is karst?
喀斯特即岩溶,是水对可溶性岩石进行以化学溶蚀作用为主,流水冲蚀、潜蚀和崩塌等机械作用为辅的地质作用,以及由这些作用所产生的现象的总称。由喀斯特作用所造成的地貌,称喀斯特地貌(岩溶地貌)。
Karstification, is mainly the chemical corrosion of water to soluble rocks, together with other geological processes, such as water erosion, suffosionand collapse. It is also a collective name for all phenomena arising from those processes. The landforms resulting from karstification is called karst landform.


(2)喀斯特地貌的形成条件 Forming conditions of karst landform
(一)岩石具有可溶性Soluble rocks
可溶性岩石是喀斯特地貌发育的物质基础,主要为灰岩、白云岩及泥灰岩等。
Soluble rocks are the material base of karst landform development, mainly includes limestone, dolomite and marl, etc.
(二)岩石具有裂隙 Rocks with fractures
孔隙和裂隙是流动水下渗的主要渠道。岩石裂隙越大,岩石的透水性越强,溶蚀作用越显著,喀斯特地貌发育越完整,并且形成一个不断扩大的循环网。
Flowing water mainly permeates along pores and fractures. 
Karstification is related to fractures, larger fractures cause more obvious karstification because of the better water permeability, which will lead to better developed karst landform. And this circle process can be continuously extended.
(三)水具有溶蚀能力 Water with dissolution capacity 
水的溶蚀能力来源于二氧化碳(CO2)与水结合形成的碳酸(H2CO3),二氧化碳是喀斯特地貌形成的功臣。
The dissolution capacity of water comes from carbonic acid (H2CO3), which is the combination of carbon dioxide (CO2) and water. Carbon dioxide is the key element related to karst landform. 
下面几个化学方程式反映了岩溶作用的进行:
The following chemical equations record the process of karstification: 
①H2O + CO2=H2CO3; ( formation of carbonic acid)
②H2CO3=H+ + HCO3-;(The dissociation of carbonic acid, to produce H+)
③H++CaCO3=HCO3-+Ca2+;(H+ reacts with CaCO3 to produce HCO3-,so that CaCO3 can be dissolved)
(四)水具有流动性 Water with mobility
流动的水溶蚀性更强烈,因为水中的二氧化碳需要得到及时的补充,水的溶蚀作用才能顺利进行,水的溶蚀能力才得以巩固加强。同时,流动的水带动河底砂砾对岩石进行机械侵蚀,更有利于岩溶作用的深入。
Flowing water has better solubility, in that the carbon dioxide in flowing water can be supplied timely and only with enough carbon dioxide, dissolution can proceed smoothly. In this case the dissolution capacity of water can be strengthened. Meanwhile, the flowing water can drive the sand and gravels at the bottom of the river to erode the rock mechanically, which will contribute to intensive karstification.

东兰地区地质演化历程 Geological evolution history of Donglan region 
东兰县及其邻区,在二叠纪及以前(距今约2.5亿年)处于浅海和海陆过渡环境,沉积了厚达3000多米的碳酸盐岩(主要为灰岩和白云岩)及少量碎屑岩(砂岩、泥岩等);三叠纪(距今约2.5~2.08亿年)因被巨厚的复理石沉积(水下泥石流)淹没而消亡,结束了海相沉积的历史,进入陆相演化阶段。
In and before the Permian (250 million years ago), Donglan county and its surrounding areas were in shallow marine and marine-continental transitional environment, and deposited carbonate rocks up to more than 3000m thick (mainly limestone and dolomite) and some clastic rocks (sandstone and mudstone, etc.). During the Triassic period (about 250 to 208 million years ago), filled with very thick flysch sediments (subaqueous debris flows), the marine deposition history was over and turned into the continental evolution stage. 
侏罗纪-新近纪(距今约2.08亿年~258万年),区域上发生了较大规模的构造运动,沉睡于海底的巨厚岩层露出水面,形成陆地,并产生了大量的褶皱、断裂,为后来形成喀斯特地貌创造了有利的条件。
In the Jurassic and Neogene (208 million years ago to 2.58 million years ago), there was a large scale tectonic movement happened in this region, as a result, the very thick strata in the bottom of the sea exposed the sea to become continent and formed a lot of folds and faults, which created advantaged conditions for karst formation.
从第四纪(距今约258万年)开始,地壳发生了多次抬升运动,构造继续发育。在雨水、生物等自然营力的精雕细琢下,形成了如今的峰丛洼地,孤峰、田园散布其中,穿洞、溶洞发育的喀斯特地貌景观。
From the Quaternary ( 2.58 million years ago), there was a series of crust uplift movements happened. Structures continued developing . Under the natural agents of rainwater and creatures, there formed karst landform with widely developed karst caves, dotted with peak clusters depressions, isolated peaks and fields.

公园地质概况 Introduction to regional geology within the Geopark 1011次播放 简介>>
东兰地区以石炭-三叠系地层分布最广,泥盆系地层零星出露,这些地层的沉积古环境以海相为主,海陆过渡相次之,陆相地层很少。岩性主要为碳酸盐岩(主要为灰岩、白云岩等),另有少量碎屑岩(砂岩、泥岩、复理石等)。
The Carboniferous - Triassic strata were the most widely distributed in Donglan region, with the Devonian strata outcropping sporadically. The sedimentary paleoenvironment of these strata is mainly marine facies, with some marine and continental transitional facies strata and few continental strata. The lithology is mainly carbonate rock (mainly limestone, dolomite, etc.), and a small amount of clastic rock (sandstone, mudstone, flysch, etc.).
区域位于“广西山字型构造”前弧西翼中段,以北西向构造和旋卷构造为主,东西向构造片段局部隐现。这些构造带及其派生的构造形迹形成极为复杂的区域构造。

The region is located in the middle section of front arc west wing of Guangxi epsilon- type structure, dominated by NW trending structure and convolute structure. The east-west tectonic section exposed partially. These tectonic belts and their associated structural features formed extremely complex regional structures.大规模的碳酸盐岩是形成喀斯特地貌的物质基础,各种构造面(断层、节理、层面等)为喀斯特地貌发育提供条件,湿润多雨的气候是雕琢大地的一双巧手。
Large-scale carbonate rocks are the material basis of the formation of karst landform. All kinds of structure planes (fault, joint, stratum, etc.) provide conditions for karst landscape development. The humid and rainy climate caves the earth.

列宁岩是一个天然的岩溶洞穴,洞口高43m,宽64m,洞深137m。列宁岩所在山体岩性为以灰岩为主的可溶性碳酸盐岩,溶洞由具有溶蚀性的地下水沿岩石裂隙长期溶蚀及其引起的崩塌形成。地层产状近水平,洞顶沿层面发生坍塌,故形成平坦的洞顶。洞内发育有石柱、石钟乳、石笋、石幔及边石坝等洞穴沉积物,洞口石钟乳下部朝洞口外弯曲生长,呈现出向光性,是由于附着在石钟乳表面的生物趋光生长所致。洞口及洞内的植被也呈现出向光性,整体向洞口外弯曲生长。此外,洞内边部有大量崩塌堆积体,是洞顶洞壁发生坍塌所致。洞内岩壁上可见小型褶皱及断裂构造。
Lenin rock is a natural karst cave, the cave of which is 43 m high, 64 m wide and 137 m deep. The lithology of the mountain where Lenin rock lies is soluble carbonate rocks, mainly consisting of limestone. This karst cave is formed by long-term corrosion from the underground water along rock fractures and the collapse caused by it. The stratum is near horizontal, and the cave roof collapses along the stratum, then formed the flat roof. There developed stone pillars, stalactites, stalagmites, curtains, rimstone dams and other cave deposits in the cave. Because of the phototaxis of creatures on the surface of the stalactite, the lower part of the stalactite at the mouth of the cave bends toward the cave mouth, which is called phototropism.. The plant vegetation in the cave or at the cave mouth presents phototaxis, grows toward the cave mouth as a whole. Besides, there are also a lot of collapse deposit, caused by the collapse of the cave wall and its roof. Small folds and faults can be seen on the cave wall.
