The difference between the crystal properties of fluorapatite and dolomite has been poorly studied. Wang Xianchen analyzed the effect of rare earth element substitution on the crystal structure of fluorapatite and its reactivity with oleic acid by studying the crystal structure properties of fluorapatite after rare earth element substitution for Ca atom (Wang et al., 2019).

The dolomite body then extends downward at c. 22 m/100 ky into an underlying broad area of partial dolomitization. This process enhances porosity at shallow depth, but beneath the dolomite body precipitation of anhydrite occludes porosity and limits the depth of reflux. In contrast, geothermal convection at the platform margin forms a smaller ...
