Whether sedimentary rocks store fossil hydrocarbons or act as impermeable layers to prevent the rise of oil, natural gas or stored carbon dioxide—all depends on their porosity. The size, shape, ...

Rocks store information from long ago. For instance, their composition can reveal the environmental conditions during their formation. This makes them extremely important in climate research. This led ...

Fine-grained sedimentary rocks, including mudstones and shales, archive processes of sediment delivery, organic matter accumulation and early diagenesis in a variety of marine and lacustrine settings.

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name ...
