Is Hainan Huaxing Hongda Industrial Co., Ltd. the largest basalt mine in Hainan?

The company is not a mineral deposit, but a unit that develops mineral deposits.

Basalt belongs to basic volcanic rocks and is mainly composed of oceanic crust. It is the most important part of the earth's ocean crust and the moon and the ocean, and it is also an important part of the earth's continental crust and the moon and land.

The occurrence of basalt shows two eruption modes: fissure eruption and central eruption, which constitute the basalt volcanic cone and its adjacent lava flow and pyroclastic rocks.

The eastern part of China, from Heilongjiang in the north to Hainan Island in the south, is a complex rock area dominated by alkaline basalt and tholeiite. Cenozoic eruption, mainly central eruption, with hundreds of volcanic cones, especially in Heilongjiang-Jilin, Inner Mongolia Plateau, Jining-Datong, Nanjing, Tengchong, Yunnan, Lei Qiong, Guangdong and Taiwan Province provinces.

Basalt is the main raw material for producing cast stone. Cast stone has high chemical corrosion resistance and acid resistance, high hardness and mechanical strength, and is widely used in chemical industry, metallurgy, electric power, coal, building materials, textile, light industry and other industries. Basalt is a raw material for producing basalt paper, lime volcano clinker-free cement, decorative board and man-made fiber, and it is also an energy-saving raw material for ceramic industry.

Domestic distribution:

There are 500 million cubic meters of basalt in Daying Mountain, Berlin, fuding city, Ningde City, Fujian Province. The ore is exposed on the ground, dark black and dignified and elegant in tone. It is a rare high-grade building board in China and belongs to one of the national building stone bases. It was named "fuding black" by the State Council General Bureau of Building Materials.

The basalt in Caidian Township, Luoyang City, Henan Province is round and massive, with large reserves. It is widely distributed about 50 cm below the surface and the depth can reach 100 meters. This kind of ore is dark black and of good quality. It is the best stone for high-grade highway pavement, airport runway and railway ballast.

There are waterfalls and waves in the north of Jingbo Lake in Ning 'an City, Mudanjiang City, Heilongjiang Province; Ying Ge Ridge has a round steamed bun shape and a pagoda shape; There are python-shaped and lava-shaped tunnels between Bohai Town and Shalan Township. The geological and geomorphological structure here is novel, diverse and colorful.

Li Quan Township, Yishui, Shandong Province is distributed in waves of 35 square kilometers, with a basalt reserve of about 35 billion tons. There are also a large number of excellent basalts in Pingyi County, Linyi City, Shandong Province.

Mingguang city basalt mineral resources in Chuzhou City, Anhui Province are rich and widely distributed in the West Sub-district Office of mingguang city City. At present, the proven prospective reserves are 65.438+68 million tons, and the proven recoverable reserves are 34 million tons, which is the largest in eastern Anhui, and the annual mining and processing capacity exceeds 6.5438+0 million tons. It has been tested by Southeast University and Tongji University as a national first-class basalt.

A large number of basalts are also distributed near Tengchong Volcano Group in Tengchong City, Baoshan City, Yunnan Province.
