近日，在貴州省遵義市道真仡佬族苗族自治縣奧陶紀白雲岩山脈深處，一條為農業灌溉開鑿的引水涵洞意外揭開了掩埋4.8億年地層下的秘境。

“這是藏在4.8億年奧陶紀地層里的洞穴”，中國地質學會洞穴專業委員會副秘書長趙揭說。

Due to the lack of human life, it is adjacent to the Dasha River Nature Reserve in Guizhou, has an excellent water source, and is filtered by hundreds of meters of dolomite layers for a long distance, and the water quality is pure, giving birth to a rare "cave sediment gene pool" in the world.

Some of the domes in the cave are more than 100 meters high, and the water droplets atomize into "aerosols" rich in calcium bicarbonate during the fall. At the bottom of stalagmites and caves, a myriad of stone flowers, stone branches, stone grapes, stone corals, etc., are condensed to form a wonder of "atomized sedimentation".

In addition, many cave beads have been found in this cave, also known as cave pearls, which are very rare. Because the texture is very good, the purity is very high, and it is crystal clear.

"I have been exploring the cave for many years, and the sediment produced in the cave is very pure, like white jade, which is not found in caves in other parts of the country." Zhao Jieyu, deputy secretary-general of the Cave Professional Committee of the Geological Society of China, said.

"In this scientific research activity, it was found that there is a cave hall of tens of thousands of square meters in the cave, thousands of pure white stone stalactites stand in it like an ice crystal forest, and the snow-white texture comes from the extremely high purity of calcium carbonate in the water and no impurity interference, and the sediment, scale, quality and type in the cave have completely changed our cognition."

Zhang Yuanhai, vice chairman of the Cave Professional Committee of the Geological Society of China and an expert in the evaluation of global geoparks, said, "Many forms (such as calcium film crystal cones) were previously only seen in theoretical models, but here they exist in the form of clusters, and this cave may be unique in China in terms of development and quality." ”
