DEFINITION of 'Gentrification'. Gentrification refers to a process of urban renewal wherein a neighborhood or city develops economically so that original residents are displaced. It is often defined by an influx of wealthier residents and businesses, resulting in an increase in property values.
Lithification (from the Ancient Greek word lithos meaning 'rock' and the Latin-derived suffix -ific) is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity destruction through compaction and cementation. Lithification includes all the processes which convert unconsolidated sediments into sedimentary rocks. Petrifaction, though often used as a synonym, is more specifically used to describe the replacement of organic material by silica in the formation of fossils.
