Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone. Limestone has a variety of origins and may be precipitated in water or secreted by marine organisms such as coral; it also may consist of the shells of dead marine organisms.

Son Doong Cave

 

Located in the limestone mountains of Phong Nha - Ke Bang National Park. Son Doong Cave was first found in 1991 by Ho Khanh, a local man. In 2009, the cave was explored and published by a group of scientists from British Cave Research Association.

Son Doong Cave was formed from 2 to 5 million years ago, when the river flowed through the limestone mountain area and was buried. The water eroded limestone and created an underground tunnel. In soft limestone areas, the collapse of tunnel ceiling formed large holes which became giant domes afterward. The cave is about 200m high, 200m wide and at least 8 5km long. Especially, Son Doong consists of two entrances, which is unique among explored caves in Phong Nha - Ke Bang National Park. Exploring the cave, visitors were surprised with spectacular scenery of numerous stalactites of which some giant stalagmites are more than 70 metres high. Deep inside the cave exists a grandiose tropical jungle called “Garden of Eden" by the explorers. The jungle is home to a diversifiedsystem of fauna and flora. Besides, the cave possesses a 2.5-kilometre underground river. Not far from the “Garden of Eden” lies an enormous “pearl collection” consisting of tens of thousands of small stone pieces in dry ponds, contributing to magnificent beauty of the cave.

The most important feature of “Garden of Eden” is ………

A.the biodiversity

B. giant stalagmites
