An additional complication has been demonstrated by Reeder and Grams (1987). They found that coprecipitation of Mg and Mn in calcites is different for different crystal faces. This results in the phenomenon of sector zoning. [Pg.92]

Possible control of trace element partitioning by factors other than elemental concentration in the fluid, for example by sector zoning (Reeder Prosky, 1986 Reeder Grams, 1987 Reeder Paquette, 1989), precipitation rate (e.g. Lorens, 1981), temperature (e.g. Mucci, 1987), competing ion effects (e.g. Pingitore Eastman, 1986), or bacterial processes (Coleman, 1993 Folk, 1993 ... [Pg.99]
