Dissolution of dolomite and doloma in silicate slag
1999年6月1日 Dissolution mechanisms of dolomite CaMg(CO3)2, and doloma CaOMgO, in a model basic oxygen furnace (BOF) slag based on the CaO–MgO–SiO2–FeO–MnO system have been characterised with regard to the reaction product phases at the dolomite/slag and doloma/slag interfaces by postmortem microstructural analysis It was found that after 1 h The main difference between dolomite and limestone is that dolomite is made up of calcium magnesium carbonate, No, dolomite is not a silicate mineral It is a carbonate mineral Is Dolomite Clastic? No, dolomite is not clastic Clastic minerals are made up of smaller pieces of rocks or minerals that have been cemented togetherDolomite: Description, Characteristics, and Other FAQsThe test for dolomite is the same as that for calcite, except that dolomite effervesces very slowly in cold dilute hydrochloric acid, and more vigorously in warm acid Dolostone is used for the same purposes as limestone with the exception of cement manufacturing LIMESTONE: Various types of limestone underlieFLORIDA’S ROCKS KEY LARGO LIMESTONE: CHERTSedimentary carbonate rocks consist predominantly of carbonate minerals (as the name implies) There are two main types of carbonate rocks, dolomites and limestones The first is modally dominated by dolomite (CaMg(CO3)2), the second by calcite (CaCO3) and there is a complete gradation between the pure dolomite and limestone “end members” indicated by the rock Metamorphism of Dolomites and Limestones Semantic Scholar

If quartz is present, the metamorphic reactions in marbles are often decarbonation reactions that involve the breakdown of carbonates to release CO 2If a pluton intrudes a limestone or dolostone, contact metamorphism may cause CO 2 to flow out of the carbonate and combine with H 2 O that comes from the pluton The CO 2H 2 O fluid can have profound effects on the
