Hi everyone,
I came to an area in my country where I notice rock made up of small black gravels. The area covered with red soil, laterite, this particular rock and thick deposit of small grain of gravel (not mixing with laterite), possibly come off from the rock. Does anyone know what it is? Can I use it as substrate?
