Geologic Principles—Cross-cutting Relationships
WebThese are cross-bedding, which is common in fluvial or eolian deposits, and graded bedding, which reflects transport by density (or turbidity) currents or, in certain cases, … Nicolaus Steno (1638-1686), born Niels Stensen, was a Danish anatomist, geologist, and later Priest who first proposed the law of cross-cutting relationships in Prodromus in 1669. Steno also proposed the law of superposition, lateral continuity, and original horizontality. Later, James Hutton (1726 -1797) … See more The law or principle of cross-cutting relationships states that any geologic feature or rock unit that cuts or deforms another is younger than the rock body or geologic … See more Understanding the type of cross-cutting relationships is important in correctly interpreting the sequence and relative age of strata, structure, or … See more You expect cross-cutting relationships to be complex in real life or your studies.
