geographical position
From the Danya mountain in Penglai, you can see a group of green islands scattered on the vast sea, like gems inlaid in the blue waves. This is the beautiful island Miaodao archipelago, which is known as the "fairyland on the sea".
Miaodao archipelago, located in the Bohai Strait between Liaodong Peninsula and Shandong Peninsula, is composed of more than 30 islands. From north to south, it can be divided into three island groups: North Island group includes nanhuangcheng Island, beihuangcheng Island, Daqin Island, Xiaoqin Island, etc.; middle island group includes Tuoji Island, Gaoshan Island, (zuoshiyouhou) Ji Island, etc.; South Island group includes Nanchangshan Island, beichangshan Island, Daheishan Island, Xiaoheishan Island, Miaodao Island, etc. Changshan island in the south is the largest with an area of 20.4 square kilometers. Miaodao archipelago belongs to Shandong Province, which is the gateway of Bohai Sea. It is not only a tourist resort, but also a military thoroughfare.
In addition to Temple Island, there is also an island famous for its beautiful Crescent Bay beach. This is North Changshan Island, which is located in the north of South Changshan Island, where Changdao County is located.
Beach Scene
The reef landscape of North Changshan island is also quite spectacular, but the most famous one is Crescent Bay, which is located at the east end of the island. Crescent Bay, also known as half moon bay, is a bay about 2.5 kilometers long, facing due north. The East and West headlands protrude in the sea, encircling the bay. Under the long-term effect of waves, it forms a quite regular Half Moon Beach. Standing at the top of a hill or cape, overlooking Crescent Bay, under the background of the blue sea, it is like a golden moon lying in the Bay, especially magical and charming.
Unique pebble
Yueya Bay is not only beautiful in shape, but also has numerous colorful pebbles on the beach. They form a colorful stone belt with a length of more than 1000 meters and a width of more than 50 meters. Visitors here, as if into a jeweled, colorful magic world! Some of them are as white as jade, some are as red as agate, some are as green as emerald, some are as bright as pearl, some are big, some are small, all kinds of colors and shapes are dazzling. Every time visitors come to Crescent Bay, they all bend over to pick up a lot and take them back as souvenirs.
The pebbles in Yueya Bay are not the common pebbles often seen on the beach, but a kind of rare pearls like jade. As early as the Song Dynasty, Su Dongpo, a famous great writer, once highly praised the Zhuji stone ball in Yueya Bay of beichangshan Island, describing it as "colorful" and "charming". He also wrote an article named "twelve stones in Beihai" for a friend who treasures the Zhuji stone ball in Yueya Bay.
The pearl stone ball in Yueya Bay, North Changshan Island, is not only used for ornamental collection because of its beautiful appearance, but also can be used as an important raw material for ceramic and metallurgical industry. The pearlite ball here is made of chert, that is, its chemical composition is silicon dioxide, its hardness is very high, it can not deform in absolute zero degree, and it can reach the heat of steel-making without melting, which is irreplaceable by metal products. Therefore, in steel-making plant, chemical fiber plant and other plants, using pearlite as the filler of oxygen catalytic machinery plays the role of separating and filtering oxygen, and enamel plant, ceramic plant, paint plant, graphite plant and so on take it as the best filler of ball mill. Local fishermen pick up a large number of stone balls from here every year to support the best packing. Local fishermen pick up a large number of stone balls from here every year to support industrial construction.
Genesis of stone ball
So, how did such a beautiful five color pearlite come into being? According to the investigation on Changshan island by geologists and geomorphologists, it is considered that the main rocks of Changshan island are Sinian metamorphic rocks and some Mesozoic Yanshanian granite porphyry. These rocks are rich in hard quartz and chert. With the rise of sea level, the Miaodao archipelago is exposed in the ocean and becomes a little island. Under the long-term erosion of the waves, some low-lying and weak places are pounded into small bays by the waves, and gradually become bays as the days grow. With the erosion of the waves, the rock gradually became a ball and pushed into the Bay, forming the Crescent Bay today.
