Organic-rich shales sampled from the aples Beach section of the Monterey Formation. Califomia. contain authigenic phosphorite phases which apparently formed within bacterial mat laminations. Light and scanning electron microscope observations show that the fossilized remains ofthese mats are similar to communities of filamentous sulfur-oxidizing bacteria found today at slope-depth, sediment, oxic anoxic interfaces. The crystal size and habits ofthe phosphatic minerals resemble contemporaf) prec1pitates in contact with pore water solutions. Mineralogical and chemical analyses ofthe most phosphatic layers show that some are a nearly pure carbonate fluorapatite (or francolite). These la)ers are lightly colored and are sandwiched between bla...
