Due to the small viscosity and high fluidity of the basalt magma, the surface of the swell is easy to form large-scale lava flow and lava, but there are also layered intrusions, such as rock beds.
In the plateau area, lava terraces with an area of ​​several thousand to hundreds of thousands of square kilometers are often formed. Some people call it plateau basalt, such as the Degan Plateau basalt in India.
In the ocean, it forms a sea ridge and a volcanic island. The minerals related to it are copper, cobalt, sulfur, ice stone, gemstone, etc., which can also be used as raw materials for acid-resistant cast stone.
Columnar joints in basalt - In basalt lava flows, vertical condensation surfaces often develop into regular hexagonal columnar joints.
The cause is generally considered to be that there is a uniformly distributed cooling center (equal equilateral triangle distribution, the cooling center distances are equal to each other) in the homogeneous basic lava, and then the respective centers are contracted to form a hexagonal columnar joint.
Tool bucket bag is a type of bag or carrier designed specifically for holding and transporting tools. It usually has a bucket-shaped design, with an open top and a wide base that allows for easy access to the tools inside.
Tool bucket bags are commonly made of durable materials such as canvas, nylon, or leather, and may have reinforced bottoms or sides to provide extra protection for the tools. They typically have multiple pockets and compartments, both inside and outside, for organizing and storing different types of tools.
Tool bucket bags are popular among professionals in various fields, such as construction, woodworking, plumbing, and electrical work, as well as DIY enthusiasts who need a convenient and portable way to carry their tools to job sites or around their homes.
