The anhydrite section can be summarized as white to milky white, soft to firm, amorphous, cryptocrystalline to microcrystalline, massive and washable; the associated dolomite section is light brown to light brownish gray moderately hard to hard, compact, cryptocrystalline to microcrystalline, sucrosic and characterized by no visual porosity.

The drilled Deep Galicia Margin sediment successions of Sites 637 to 641 start in the Tithonian with limestones containing sandstone and claystone interbeds followed by dolomitized platform carbonates with marly beds as well as low-relief biohermal mounds and overlain by Early Berriasian sucrosic dolomite possibly deposited as shallow marine echinoid-ooid-skeletal grainstone and packstone.
Petrographic analysis suggests that two phases of dolomite precipitation are present: the first consists of a fine-grained, fabric-destructive cement that probably accompanied early burial; the second is a fine- to medium-grained, locally sucrosic dolomite that is interpreted to have precipitated during later burial.
