What is the sea between Taiwan Province Province and the mainland?

Chinese mainland and Taiwan Province Province are separated by the Taiwan Province Strait, which is a narrow waterway connecting the East China Sea and the South China Sea. The Taiwan Province Strait is bounded by the East China Sea of China in the north and the South China Sea in the south. Taiwan Province Strait, referred to as "Taiwan Province Strait" for short, is a strait connecting the South China Sea and the East China Sea between Fujian Province and Taiwan Province Province.

From Fuguijiao, Taibei County, Taiwan Province Province, to Pingtan Island, Fujian Province in the north, to Dongshan Island, Zhangzhou, Fujian Province in the south, and to Eguanbi, Taiwan Province Province in the south. Mainly continental shelf, with an average water depth of about 60 meters and the deepest water depth of 88 meters. In addition to the coastal islands near Fujian, there are Penghu Islands and Little Ryukyu Islands in Pingtung County, Taiwan Province.

The traffic status of Taiwan Province Strait in the East China Sea became one of the areas where Li Dan, Zheng Zhilong, Lin Daogan and other maritime armed groups were active in the Ming and Qing Dynasties, and the Taiwan Province Strait became the inner lake of Zheng Zhilong and his successor Zheng Fleet.

Zheng Zhilong took South China, Taiwan Province Province and Japan as the activity stage, and operated Hirado Island, Nagasaki and Manila in Japan, forming the main commercial navigation channels in South China and Southeast Asia. The Taiwan Province Strait is also the main sea area for the activities and battles of maritime armed groups.

The Formation of Taiwan Province Strait

As early as 600 million years ago, when the late Paleozoic orogeny began, the "Taiwan Province Beach" appeared in the Taiwan Province Strait, which is the shallowest place in the Strait with a depth of only 20 meters. At the beginning of the late Pleistocene Ice Age, the sea receded, and the depth of the strait dropped by130-180m, becoming land and connecting with the mainland. A large number of ancient humans and animals migrated from the mainland to Taiwan Province Province through the Taiwan Province Strait and became land.

In the 1970s, ammonite fossils were found in the oil exploration in Beigang area of Taiwan Province Province, which is the standard fossil of Mesozoic, proving that in the Triassic and Jurassic periods of Mesozoic, although seawater appeared in many places between the two sides of the Taiwan Strait, it was mainly land. The crustal movement in the Taiwan Province Strait has not stopped. Until1920,000 years ago, between Jurassic and Cretaceous in Mesozoic, there was a violent crustal movement on both sides of the strait, at which time Taiwan Province Province began to become land. In geological history, Taiwan Province Province called it "South Australia Movement" (that is, schist in Da 'nan 'ao evolved into marble), while mainland China called it "Yanshan Movement".

The initial formation of the Strait began in the Cretaceous and Paleocene, that is, 54 million years ago, the central part of Taiwan Province Province began to be submerged, and the middle part became a shallow sea and began to become a strait. During the early Eocene crustal movement, the Taiping movement began in Taiwan Province province, and the Maoshan movement began in the mainland, and the land on both sides of the strait became one piece. Until the Quaternary Pleistocene, the granite in South China began to desert, and the timely and mica in the rocks were alluvial to the lower part of the Taiwan Province Strait. Today, the northern and central parts of Taiwan Province Province have been extensively mined and become important raw materials for the glass industry in Hsinchu.

Since the Quaternary Ice Age (654.38+08000 -6000), seawater has entered a period of transgression, and the sea level rose by 654.38+000-654.38+030 meters, forming today's sea level, and the Taiwan Province Strait began to form. Since then, cross-strait exchanges have shifted from land to sea.
