What term do we use to indicate that the sedimentary context of a site is not disturbed?

The term used to indicate that the sedimentary context of a site is not disturbed is "in situ." This Latin phrase translates to "in its original place" and is commonly used in geology, archaeology, and sedimentology to describe sediments or artifacts that remain in the location where they were originally deposited, without having been moved or altered by subsequent processes. This condition is crucial for accurately interpreting the geological or archaeological record, as it helps ensure that the observed features and associations reflect the true historical context of the site. In situ conditions allow for more reliable scientific analysis and understanding of past environments and human activities.
