Pros & Cons of Landscaping Ground Cover Rocks
Pros: More Durable. In certain parts of your home's landscape, durability is an important factor. This is especially true in areas such as walkways or a driveway where organic or living ground covers would be easily trampled or destroyed by visitors or cars. Gravel and other forms of rock ground cover stand up to heavy use.
What are the pros and cons of different rock dusts?
Basalt rock dust: Some sources say basalt rock dust is the optimal kind of rockdust, and I've never heard anyone deny that directly. It has less silica than Azomite and diatomaceous earth, for sure. It is higher in other minerals, however. It is said to be high in ferrous minerals. I've seen differing compositions listed for basalt rockdust.

Rock 'flour' from Greenland can capture significant CO2, …
However, the rock flour is much finer than the ground basalt and so exposes more surface area to weathering. The advantages and disadvantages of both types of rock dust are still being studied.
What are the disadvantages of basalt?
Basalt is a common volcanic rock that is formed when lava from a volcano cools and solidifies. It is known for its durability and strength, making it a popular material for construction purposes. However, like any other material, it also comes with its own set of disadvantages. One major disadvantage of basalt is its high cost.
