This technique is only used for creating a "Japanese" stepping stone path. The stones have to be wide and thick enough, and properly wedged into the soil to offer sufficient stability. Start by planning where each paving stone will be laid and set out the emplacements by sprinkling plaster on them. As for laying the stones, no special procedures are needed, apart from ensuring that when they are in their final position, their surface remains slightly below the soil level. This will ensure that lawnmowers can pass over them without problem.
Sedimentary rocks are the result of the accumulation and compacting of mineral debris (i.e. other stones), organic debris (animal remains and vegetation, fossils), or chemical precipitation.
They are exogenous rocks, i.e. rocks which are formed on the surface of the Earth. Sedimentary rocks are present on 75% of the surface of the Earth's continents, but when considering its crust as a whole (from the surface to a depth of 22 miles (35 km)), they only represent 5% of its total volume.
The main sedimentary rocks are:
