大纲/内容
the formation progress different from noramal limestone caves
hydrogen sulfide+oxygen=sulfuric acid
bacteria feed on oil and release hydrogen sulfide gas
sulfuric acid dissolves limestone-bigger cracks-get passageways
moving water makes passageways

carbonic acid helps solve the rock
moving water forms most of the world's limestone caves
evidences shows that Lechuguilla cave has no flowing water
not all passageways have an opening to the outside world
There are many gypsum deposits and water can dissolve gypsum-if 有水，就不会残留gypstum
other similar caves is forming now
in Mexico,researchers see and smell the sulfuric acid and gas
