WebJun 2, 2024 · Jarosite and alunite can occur in sedimentary rocks, but typically they are only present as minor phases mixed in with an assortment of other minerals. For example, jarosite commonly occurs as a tertiary weathering product of pyrite in sedimentary rocks and is present in minor amounts co-occurring with pyrite and hematite [ 33 , 34 ]. WebLithification (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.
