classification of sedimentary rocks,calcite or dolomite: limestone: chiefly calcite, massive dolomite (dolostone): chiefly dolomite, massive chalk: chalky texture tufa: very porous, friable travertine: bonded, coherent, denser than tufa caliche: lime-rich deposit formed near surface: calcareous shale: limy.sedimentary rock - carbonate rocks: limestones and dolomites,limestones are for the most part primary carbonate rocks. they consist of 50 percent or more calcite and aragonite (both caco3). dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [camg(co3)2] replaces the calcite and aragonite minerals in limestones during diagenesis..

it is also used as slag in the iron and steel industry. the slag which is formed by limestone has a very low melting point which makes the process of gangue removal easy. dolomite – when the amount of magnesium is reached at a certain level in the limestone, it is converted into a different carbonate known as dolomite. unlike limestone, dolomite has industrial uses.
limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (caco 3) and dolomite (camg[co 3] 2). almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be debated.
these soil amendments should never be confused. routine and frequent application of gypsum is required for the sustainability of all irrigated soils1; and while limestone, dolomite and other liming materials are necessary to neutralize soil acidity problems, improper usage of these liming amendments will actually result in harm to crops and plants.
a different processing method produces pool filter de, which must not be used in the garden or home. de is mostly silicon dioxide, not calcium. and dolomitic limestone is not derived from the skeletons of little animals but is a sedimentary rock. clear as mud? here is a link that might be useful: dolomite information
limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. the process of iron making is
dolomite lime comes from underground limestone deposits. in nature, it can form white, tan, gray, or pink crystals. dolomite lime can appear in nature as white, tan, gray, or pink crystals. dolomitic limestone is often processed into dolomitic lime pellets or powder.
created when limestone and lime mud interact with magnesium-rich groundwater, dolomite is a sedimentary rock known for its characteristic white and gray coloring. while often mistaken for marble or quartzite, this natural stone has distinct features which separate it from all others.
what is the difference between limestone and dolomite? • limestone is a calcium carbonate mineral whereas dolomite is made of calcium magnesium carbonate. • sand, clay and silt are commonly found in limestone as impurities but not quite common in dolomite. • calcite limestone is usually more expensive than dolomite. read more: 1.
as nouns the difference between limestone and dolomite is that limestone is (mineralogy) an abundant rock of marine and fresh-water sediments; primarily composed of calcite (caco₃); it occurs in a variety of forms, both crystalline and amorphous while dolomite is (mineral) a saline evaporite consisting of a mixed calcium and magnesium carbonate, with the chemical formula ca]]mg(c[[oxygen|o 3) 2; it also
difference between limestone & dolomite ? limestone is a calcium carbonate mineral whereas dolomite is made of calcium magnesium carbonate. sand, clay and silt are commonly found in limestone as impurities but not quite common in dolomite.
the specific heat capacity of limestone is 0.91 kj/kg k and that of dolomite is 0.92 kj/kg k. depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.limestone is pressure resistant whereas dolomite is heat resistant, pressure resistant, wear resistant.
limestone is made of calcium carbonate. dolomite is made of calcium magnesium carbonate. age and formation. throughout the last billion years, much of alberta was covered by an ocean. the ancient lime-rich ocean sea floor and coral reefs are preserved as limestone and dolomite.
the primary difference between the two materials is that, in addition to containing calcium carbonate, dolomitic lime also contains a mixture of magnesium carbonate. typically, the mineral is comprised of approximately 50% calcium carbonate and 40% magnesium
dolomitic lime (often referred to as dolomite) is slightly different from agricultural lime. this particular material is manufactured by way of crushing dolomitic limestone into fine particulate matter. because it is a type of limestone, you can count on the fact that it will also contain a very high calcium content.
from mineral composition the dolomite and calcite that forming limestone are carbonate but anhydrite is from sulfates it is a salt but the2 others
when ordinary limestone is ground up, the resulting product is known as calcitic aglime because ordinary limestone supplies only calcium. dolomite is a type of rock that is similar to limestone,...

what is the difference between limestone and dolomite? limestone is a calcium carbonate mineral whereas dolomite is made of calcium magnesium carbonate. sand, clay and silt are commonly found in limestone as impurities but not quite common in dolomite. calcite limestone is usually more expensive than dolomite.
the main difference between the formation of limestone and dolomite is that dolomite contains more magnesium. dolomite is sometimes even formed from limestone, as limestone is modified by magnesium-rich limewater. the resulting rock may be
when using both forms of limestone, better ph control can be achieved; calcitic limestone quickly releases and adjusts the growing medium's ph while dolomitic limestone slowly releases over the course of the crop, resulting in limited ph fluctuations during production. for more information, contact your premier tech grower services representative:
dolomite (noun) a kind of sedimentary rock resembling limestone but consisting almost entirely of the mineral dolomite. dolomite (noun) a light colored mineral consisting of calcium magnesium carbonate; a source of magnesium; used as a ceramic and as fertilizer
dolomite is slightly harder than limestone. dolomite has a mohs hardness of 3.5 to 4, and limestone (composed of the mineral calcite) has a hardness of 3. dolomite is slightly less soluble in dilute hydrochloric acid.
