In the production process of basalt stone,we will pay special attention to the main production sites.Here,the editor will introduce two injection methods in the production process of basalt stone.Today,let's follow the editor to learn more.
1.Intermediate injection
Lava flows and volcanic debris rocks form basalt aggregates and nearby volcanic cones.East China,starting from Heilongjiang in the north and ending at Hainan Island in the south,is a composite rock area dominated by alkaline basalt and porphyry basalt.In the Cenozoic,it was dominated by intermediate eruption,with hundreds of volcanic cones,especially Heilongjiang Jilin,the Inner Mongolian Plateau,Nanjing,Yunnan Tengchong,Guangdong Leiqiong and Taiwan.
2.Fissure jet
Generally speaking,it constitutes a large area of basalt stone.Floods and fractured jet streams are often depicted as embankments similar to basalt,but they are often buried by later rock flows and are not easily found.Emeishan basalt is an example,which is widely distributed in southwestern China.Formed in the Late Permian,with a scattered area of about 260000 square kilometers and a typical thickness of 600 to 1500 meters,with a thickness of over 3000 meters in the west.It belongs to Laban basalt and is obviously rich in titanium dioxide.In basalt and floods,the uniform thickness of a single rock flow is about 10-100 meters,and the flow interval can reach 100-150 kilometers or more.The basalt in a region is usually composed of several or dozens of injections,with intervals that can be long or short,some of which can last for hundreds of thousands of years.
That's all for the two spraying methods of basalt stone that the editor has compiled.Everyone must pay attention when using it.
