What rocks are impermable?
As a general rule, igneous rocks are impermeable. Metamorphic rocks may also be impermeable, but this will depend on the mineralogy and level of metamorphism. These rocks are impermeable because they have crystals which interlock, forming a watertight structure. This is the rule, but there are exceptions. Sedimentary rocks tend to be permeable or porous, and many will even dissolve, or their cement will dissolve in water. This is because of their often clastic structure which has some holes in it.
What type of rock is groundwater found in?
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
Are the oldest rocks on Earth in the Grand Canyon?
Not hardly. The oldest rocks at the bottom of the Grand Canyon are around 2 billion years old. The oldest rock discovered on Earth of terrestrial origin is around 4.28 billion years old.
How old are the rocks of the Grand Canyon Super group Where does that fit in on the geologic time scale?
hi
Why are igneous rocks impermeable?
because of the rocks structure and weight. this makes it.

no
What rocks cause rapid runoff?
Impermeable rocks cause more rapid run off than permeable rocks. This is because the water can somewhat flow through the permeable rocks, not impermeable ones.

What are permeable and impermeable rocks?
Permeability is a measure of how well a porous media transmits a fluid. It has nothing to do with the fluid itself. It is measure in (length)2. The Hydraulic Conductivity is a measure of how easily water moves through the porous media. It depends on the permeability of the matrix, but also is a function of the fluid. It is a measure of (length)/(time)
