Metamorphic Grains Non-porous
Sedimentary Crystals Porous

How does metamorphism affect the Earth’s rock formation?

The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks.

Why metamorphic rocks are less porous than sedimentary rocks?

Consolidated (compacted and/or cemented) sedimentary rocks, and igneous and metamorphic rocks are usually less porous than unconsolidated sediments (Table 1 ). Igneous and metamorphic rocks generally have very low porosity, because of their interlocking crystals.

How deep should a rock be for landscaping?

The suggested depth of coverage varies according to the size of the individual stones. If the stone size is 1/2-inch or less, the suggested depth is 2-inches. Stones that are 3/4-inch to 1-inch should have a depth of about 3-inches. Stones that are 1-inch or larger should have a depth of 4-inches.
