Unconformity

A surface of erosion or non-deposition that separates younger strata from older rocks, indicating a gap in the geologic record.

Conglomerate

A conglomerate is a coarse-grained sedimentary rock composed of rounded fragments larger than 2 mm in diameter, embedded in a matrix of finer particles and cement.

Shale Layer

A shale layer is a sedimentary rock formation characterized by fine-grained clay particles, often found in various geological strata and known for being a source of oil and natural gas through hydraulic fracturing.
