Witherite is also formed from Calcite that loses the calcium element which instead gets replaced by barium, thus forming Witherite in the process. Thin, long crystals and aggregates of Witherite should be handled carefully, as they are fragile and easily damaged.

Oct 15, 2020 The process is widely considered to be geologically slow and typically fills pore space. Diagenetic calcite is thus generally anhedral with a smooth, featureless surface texture in the SEM (e.g., P rez-Huerta et al., 2018). Below the K–Pg boundary, we observe predominantly irregularly shaped, larger micrite crystals that we link to ...
