Mudstone and shale are two common terms in geology that describe rocks. Mudstone is a type of sedimentary rock that forms from the deposition of clay and mud ...What is shale gas and tight gas? Shale gas is natural gas that is trapped within shale formations of rock. The rock is impermeable, meaning liquids cannot pass through, which makes it harder to extract. Tight gas is held in rock pores 20,000 times narrower than a human hair. A special technique, known as hydraulic fracturing, is needed to ...Shale gas is a form of natural gas (mostly methane), found underground in shale rock. It is classified as ‘unconventional’ because it is found in shale, a less permeable rock formation than sandstone, siltstone or limestone in which ‘conventional’ gas is found, and it is generally distributed over a much larger area.There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.
