任务：
观察： 描述岩石的表面。你能认出尖锐的山脊、沟槽或凹陷吗？它们是什么形状？
测量： 测量典型凹槽或缝隙的深度。(提示：使用尺子或硬币等比较物体）。
水和石头： 想象雨水是如何流过岩石的。你在哪里看到水长期塑造石头的痕迹？
请给自己或现场物品拍一张照片，以证明您的访问，并将其附在您的日志中。
将此缓存记录为 “找到了”，并将问题答案发送至 “silka03.earthcache@gmail.com ”或通过 Geocaching 消息中心发送给我。不要写在日志中！
然后您可以立即登录。如果有任何问题，我会通知您。
玩得开心
这个地球寻宝游戏将带您到一个令人印象深刻的喀斯特风化实例。在这里，您可以观察到大自然的力量，它在数千年的时间里塑造了岩石。石灰岩是喀斯特地貌的主要岩石，主要由矿物碳酸钙（CaCO₃）组成。它是一种沉积岩，通常由珊瑚和贝壳等海洋生物的残骸形成。其典型的浅灰色，有时带有化石印记，显示了其起源。
什么是岩溶？
喀斯特地貌是富含碳酸盐的岩石（如石灰石、白云石）在水中被碳酸溶解而形成的。当雨水进入地下时，会吸收空气和土壤中的二氧化碳（CO₂），形成弱碳酸：
这种微酸性的水渗入石灰石的裂缝中，逐渐溶解碳酸钙：
由此产生的碳酸氢钙（Ca(HCO₃)₂）可溶于水，被雨水冲走。经过数千年的发展，就形成了这样的特征形态：
卡伦（石灰岩路面）： 石灰岩路面：地表上的沟槽状凹陷。
洼地： 因地下洞穴坍塌而形成的漏斗状凹陷。
洞穴： 水在地下流动的较大洞穴。
烟囱和裂缝： 水渗入岩石的垂直通道。
您在这里看到的尖锐山脊和不规则凹陷就是这一过程的结果。每场雨水都会带走一小块岩石，这是一个缓慢而持续的变化过程。
Tasks:
-
Observation: Describe the surface of the rocks. Can you recognize sharp ridges, grooves, or depressions? What shape do they have?
-
Take Measurements: Measure the depth of a typical groove or crevice. (Tip: Use a ruler or a comparison object like a coin.)
-
Water and Stone: Imagine how rainwater flows over the rocks. Where do you see signs that water has shaped the stone over a long period?
-
Please take a photo of yourself or an object on site to prove your visit and attach it to your log.
Log this cache as “Found it” and send me the answers to the questions to “silka03.earthcache@gmail.com” or via Geocaching Message Center. Not in your log!
You may then log immediately. I will let you know if anything is wrong.
Have fun!
This EarthCache takes you to an impressive example of karst weathering. Here you can observe the power of nature, which has shaped the rock over thousands of years. Limestone, the dominant rock in karst landscapes, consists mainly of the mineral calcium carbonate (CaCO₃). It is a sedimentary rock, often formed from the remains of marine organisms such as corals and shells. The typical light to gray color, sometimes with fossil imprints, reveals its origin.
What is Karst?
Karst landscapes are formed by the dissolution of carbonate-rich rock (e.g., limestone, dolomite) by carbonic acid in water. When rainwater hits the ground, it absorbs carbon dioxide (CO₂) from the air and soil, forming a weak carbonic acid:
This slightly acidic water seeps into cracks and crevices of the limestone and gradually dissolves the calcium carbonate:
The resulting calcium bicarbonate (Ca(HCO₃)₂) is soluble in water and is washed away by rain. Over thousands of years, characteristic forms such as these develop:
-
Karren (Limestone Pavements): Groove-like depressions on the surface.
-
Dolines: Funnel-shaped depressions formed by the collapse of underground cavities.
-
Caves: Larger cavities where water flows underground.
-
Chimneys and Crevices: Vertical channels through which water penetrates the rock.
The sharp ridges and irregular depressions you see here are the result of this process. Every rain shower carries away a small piece of the rock – a slow but constant transformation.
