Dual-Energy Micro-CT and K-Edge Subtraction Micro-CT of Darai Limestone The Darai limestone is a fossil rich dolomitized limestone from Papua new Guinea with many nanoporous regions. The sample was prepared as a mini-core 3.8 mm in dameter and ~6-mm long. Porosity was estimated from the difference in wet and dry mass to be 16.4 (4)%.

2. Chemical Sedimentary Rocks. Chemical sedimentary rocks are formed when the water components evaporate, leaving dissolved minerals behind. Sedimentary rocks of these kinds are very common in arid lands such as the deposits of salts and gypsum. Examples include rock salt, dolomites, flint, iron ore, chert, and some limestone. 3.

Dolomite, CaMg (CO3)2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium. Calcite in limestone is divided into low-magnesium and high-magnesium calcite, with the dividing line placed at a composition of 4% magnesium.
