Christmas 2008: Many moons ago, I travelled to Shaoguan to ogled up close and personal with some of Southern China's famous landforms like castles, teapot, phallus and vulva of Danxia Shan. Well, one need a bit of imagination to see them. Loads of lols! #danxiashan #travel #landform #petrographic #geomorphology #limestone #conglomerates #sandstones #pseudokarst #danxialandform #cretaceous #geology #rocks #cliffs #exploration #adventure #traveler #shaoguan #china
Sunday Geology-in-the-Movies Quiz: Three point quiz! (A ) What movie (picture on right ) was inspired by the landscape on the left? (B ) Where in the world is the landscape on the left? (C ) What rock type makes up the landscape? ANSWERS: (A ) Avatar (B ) Zhangjiajie, Hunan, China (B ) SANDSTONE! Surprisingly, this landscape is not karst. The rocks are marine sandstones that have been weathered along fractures and eroded by mass wasting and streams (rather than a product of dissolution, which is essential for karst ).
"Danxia landscape" of southeast China. Danxia is the term used by Chinese geologists for this peculiar landscape made by sandstone red beds. Some landforms look like karst (a limestone landform ) so they are also called "pseudokarst". This area was the birthplace of Taoism, the philosophy involving ying and yang.
A rickety walkway wraps around a mountain of sandstone. These towers are made of sandstone and breccia (a coarser-grained sedimentary rock with angular fragments ) and were part of a large alluvial fan that filled a rift valley in southeast China. Erosion by streams has left these isolated towers.
More photos from southeast China where Cretaceous red beds of sandstone and breccia form "pseudokarst" geomorphology. These sedimentary rocks formed as alluvial fans on the margins of Cretaceous rift basins. Interbedded sand dune deposits suggest a desert environment probably much like what Death Valley looks like today. No dinosaur fossils are found in this area. Further north, in more mild conditions, dinosaur remains, including eggs, have been found. These landforms were the inspiration for the Hallelujah mountains in the movie Avatar. #geology #geoporn #geologyporn #danxia #fujian #china #pseudokarst #landscape #landform #geomorphology #cretaceous #redbeds
