Random good picture Not show

31. The dynamic behaviours of homogenous materials, such as quartz, calcite and wolframite in grinding mills are examined.

32. There are not only illite, but also asphalt, microcrystalline quartz, dolomite, calcite, anorthite, gypsum, and such as potential damage materials.

33. The constructive diagenesis are mainly epigenic karstification and burial dissolution. The destructive diagenesis are filler in each periods, the most devastating cement to porous is sparry calcite.

34. Associated Minerals are halite , calcite , sulfur , pyrite , borax and many others.

35. X-ray studies show that carbonate minerals are aragonite, high-Mg calcite, and lesser dolomite, ankerite and siderite.

36. The vacuum itself is polarized, becoming strongly birefringent, like a calcite crystal.

37. The major nonmetallic minerals are quartz, chansthealite, and miner ores are calcite, ankerite. illite hydromica and other clay minerals.

38. The ore - hunting indicator is of calcite - potassium feldspar veins containing pyritohedron pyrite.

39. Rock-forming mineral, olivine, pyroxene, hornblende, orthoclase, feldspar, plagioclase, mica, quartz, biotite, calcite and other common metal and nonmetal minerals.

40. The remnant intergranular pores were filled with this kind of late calcite cement, which leads to a great decrease of the effective porosity.

41. Calcite is the dominant gangue mineral in the Furong tin polymetallic deposit.

42. By making use of the rotating disc apparatus and macromolecular biocatalyst, the authors have studied the kinetics of calcite dissolution in CO2-H2O solutions with turbulent motion.

43. The main type of carbonate cement was calcite cementing, with little ferrocalcite cement and rare ferrodolomite cement.

44. The chemical composition of the melo shell is calcite and aragonite.

45. To his astonishment, he saw one of the double images disappear as he rotated the calcite.

46. The study on massive hydrogrossular by means of polar microscope, infrared spectra and Xray shows that it consists mainly of hydrogrossular, with a little amount of diopside and calcite.

47. On the basis of crystal structure and crystal chemistry theory, according to the crystal cell parameters, the atomic arrangement of calcite, etc.

48. The result indicates that when the diopside's content increases, the content of the quartz, sericite and calcite decreases, and the boudin 's viscosity increases.

49. The acicular and columnar shapes of aragonite crystals are preserved even after aragonite changes into calcite.

50. Analcime is distributed in sparry calcite cement, while natrolite is in quartz and feldspar clastic particles.

51. So, the extension fractures were often distributed together with shear fractures, and the tension fractures were developed partly with lens veins filled by asphaltum or calcite.

52. The seeming disorder of calcite highlights the geometric precision of fluorite.

53. Dolomite can exsolved not only from magnesian calcite under metamorphic conditions, but also from magnesian calcite sediments under a modest pressure in a normal oceanic environments.

54. Diagenetically authigenic minerals are dominantly kaolinite, chlorite, siliceous,[http://sentencedict.com/calcite.html] and ferruginous calcite.

55. The results show that an allowable supersaturation without the precipitation of calcite scaling existed.

56. We can be conviniently studied with reference to a crystal of calcite or Iceland spar.

57. Calcite cementation seens a possibility where lime grains or calcareous organisms are abundant.

58. Most dolomite is obviously the result of replacement of precursor calcite but certainly not all.

59. Vein minerals are mainly in quartz, Calcite, diopside and garnet etc.

60. The result of gravity separation for quartz - calcite type scheelite is not ideal.
