It's a residual mountain(unaka) which were a set of thrust blocks under the erosion unconformity.It's reservoir pore space is a fracture-vug-pore system of Ordovician carbonate karst.
The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.
Scientific investigations prove that the mountains here are of a limestone composition, and that the Yellow Dragon is actually a geological formation unique to a karst region.
Over millions of years, rivulets have carved into the stone, creating networks of caves, treacherous sinkholes, and imposing towers of rock called " karsts" .
Going further into what causes them, one recent study looking at a karst region in Spain found that sinkhole activity is intensified during drought periods.
Sinkholes can most notably be found in karst terrains, which is a term for places throughout the world whose features are largely influenced by underground drainage.
In China, there are quite some splendid landscapes formed by karst structures, such as the Guilin Landscape in Guangxi and the Stone Forest in Yunnan, each with a distinctive feature, however.
Jiuzhaigou Valley has been described as a fairyland, because of its many waterfalls, snow-covered karst mountains, and its 108 blue turquoise and green colored lakes that are so crystal clear, one can see the bottoms.
Set deep into the surrounding rainforest and karst cliffs, the caves are record-breakers in several ways Kayaking, mountain biking, and taking a walk in the 500-meter-long canopy skywalk are also popular park activities.
In front of the monastery, there lies a karst cave of immeasurable depth, while behind it, there is a stone tablet. All but the top of the tablet has been buried in calcium carbonate, so that the inscriptions are unreadable now.
