Several of these crystals exhibit hopper-growth, a condition occuring when crystal edges grow more quickly than the centers. The pink color is due to algae in the crystallizing solution.Web
ادامه مطلبThe growth morphology of the halite crystals on the floor of the brine pool is controlled by the density of nucleation of the surrounding crystals, saturation levels, rates of ionic diffusion and the attitude of the parent crystals (Arthurton 1973; Gornitz and Schreiber 1981; Lowenstein and Hardie 1985). In an uncrowded situation, cubes are ...Web
ادامه مطلبWhen crystals grow by evaporation from aqueous solution the perfection of the cube faces is usually lost; owing to the high values of the supersaturation, hopper shaped {100} faces appear along with dendritic branches developing in the <111 > directions.

ادامه مطلبIn this exercise, the class will grow a variety of crystals of the same mineral, but with different chemical compositions. These crystals will be made from mixtures of halite (NaCl) and sylvite (KCl) that are melted and cooled. Because K+1 is significantly larger than Na+1, the unit cell is larger in sylvite than in halite.Web
ادامه مطلبThe reports of halite crystals growing subaqueously in the bottom muds of the Dead Sea (Neev and Emery, 1967) is of particular interest in this discussion.
