>If memory serves, geologists have a problem explaining thick anhydrite sequences. The problem is exacerbated because there's no modern analog. Regardless of how serious their problem may be, it's not as serious as the YEC's problem of trying to explain such sequences by a flood model without an ad hoc miracle. <
There are smaller-scale modern analogs, resulting in general agreement about a large, evaporative basin setting for their formation, e.g, the Mediterranean during the late Miocene, cut off from the ocean at both ends. However, details such as how much water might still be present (was the deep Mediterranean a very salty sea or a salt flat?) remain uncertain.
