As said earlier, world of sands can be divided into two major parts – mineral sands and biogenic sands. These sand types occur often separately but they can also mix in all proportions and form hybrid carbonate-silicate sand type.
This sand type is also found in low latitude beaches as biogenic sands and it is very common. It is usually a mixture of biogenic and volcanic or biogenic and continental sands.
