It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of Limestone

We would like to show you a description here but the site won’t allow us. The core ingredient of all gypsum plasters is gypsum rock–hydrous calcium sulfate–which has a water content of about 20% in chemical combination. During processing, about 3/4 of this chemically combined water is removed from the gypsum rock employing a controlled heating process called calcination. Gypsum rock is one of the main types of evaporite deposit, along with anhydrite and half water gypsum (Stawski et al., 2016; Warren, 2006; Zhu, 2008). Gypsum rock is an important cap rock because it has an extremely dense structure and low porosity and permeability (Beydoun, 1998; Chen et al., 2005; Yao, 2007; Zhu et al., 2014). It is also a ...Sedimentary Rocks. Clastic Rocks and Coal. Limestone and Dolostone (Biochemical Rocks) Evaporites. (Halite and Gypsum) Sedimentary Structures.
