Extreme acidic environments associated carbonate Mound the western Great Artesian Basin
2012/3/30
The carbonate mound springs of the western Great Artesian Basin (GAB) are natural discharges for artesian groundwater, forming distinct geomorphological features. They are generally located along faul...
Characterization method of Limestone according to the Formation Age on manufacturing process of aragonite precipitated calcium carbonate
Characterization method Limestone the Formation Age manufacturing process aragonite calcium carbonate
2012/3/28
Korea has about 68 hundreds million tons of limestone's reserves. Still, high-Ca2+ limestone containing more than 52% calcium oxide makes up for about 12% only; hence the need for securing and effecti...
Manufacturing Characteristics of Precipitated Calcium Carbonate according to the Formation Age of Limestone
Manufacturing Characteristics Precipitated Calcium Carbonate Formation Age Limestone
2012/3/28
Limestone is abundant mineral that has occupied about 14% of the earth's crust and 20~30% of the sedimentary rock all over the world. As extensive distribution, limestone contains various minerals suc...
Tensile strength of sand, palygorskite and calcium carbonate mixtures and interpretation with the effective stress theory
Indirect tensile strength Palygorskite Calcium carbonate Effective stress Compaction Central Iran
2011/11/4
Many soils in arid regions of the world including those of central Iran contain palygorskite and carbonates in their mineral fraction. There is, however, little information on the effects of these min...

Complex Formation of Cation-Exchanged Montmorillonites with Propylene Carbonate: Osmotic Swelling in Aqueous Electrolyte Solutions
Infra-Red Spectroscopy Intercalation Complex Montmorillonite Osmotic Swelling Propylene Carbonate
2011/12/7
Abstract: Montmorillonites saturated with Li+, Na+, K+, NH4+, Mg2+, Ca2+, Ba2+, or Ni2+ ions can form complexes with propylene carbonate (PC) by intercalation; the d(001) of montmorillonite expands to...
Burbankite, a (Sr,REE,Na,Ca)-carbonate in fluid inclusions from carbonatite-derived fluids: Identification and characterization using Laser Raman spectroscopy, SEM-EDX, and synchrotron micro-XRF analysis
Burbankite synchrotron micro-XRF analysisp SEM-EDX Laser Raman spectroscopy
2012/3/31
Burbankite, ideally (Na,Ca) (Sr,REE,Ba) (CO ) , is a rare REE carbonate mineral that until now
had been encountered only at a few localities including highly alkaline silicate rocks, carbonatites,
