(2) Platforms where only the fast growing rim and patches of the in- 

 terior are able to match sea- level rise while the remainder of the platform is 

 drowned (temporarily) . 



(3) Platforms which keep up and maintain a flat top at sea-level and 

 contain shallow-water sediments whose thickness at the least matches the 

 height of the sea-level rise. If terrigenous supply is limited, prograding 

 sheets of shelf carbonate occur (frequently capped by supratidal evaporites) , 

 with prograding shelfmargin carbonate clinoforms and turbidites. If 

 terrigenous supply is high, the shelf carbonates encroach on deltas. 



b. Relative drops in sea- level (caused by crustal uplift or by 

 subsidence being outpaced by a eustatic drop in sea-level) cause karst and 

 soil development over shelves sand platforms, deposition of "deep-water" 

 evaporites in adjacent semi-enclosed basins and in open marine basins the 

 deposition of deltaic and aeolian elastics that bypassed the shelf. 



Falls are accompanied by platform-wide fresh-water digenesis. During 

 the relative sea- level rises marine digenesis is common in the subtidal por- 

 tions of the shoaling-upward carbonates, and fresh-water digenesis and dolo- 

 mitization and sulphate deposition is common in their intertidal and supra- 

 tidal portions. 



The stratigraphic significance of these responses to relative sea- level 

 change is that many are tied to eustatic events and so are predictable within 

 a basin of deposition. (Authors).

 (Greece) - A Detailed Record of Eustatic Sea-Level Variations During the Last 

 500,000 Years," Marine GeoloEV . Vol 77, pp 99-107. 



Between Corinth and Xylokastro 20 marine terraces reflect the 

 interaction of the northern Pelponnese uplift an the global eustative sea- 

 level fluctuations during the last 500,000 years. Correlation of the terraces 

 with oxygen- isotope records in deep-sea cores allowed accurate dating of these 

 fossilized transgressive shorelines. Curves of altitude versus age have been 

 plotted; they show a regular decrease of the uplift rate and a frequent return 

 of the sea- level very close to the present-day one, not only during the 

 interglacial periods (5, 7, 9, 11, 13) but also during glacial periods (3.1, 

 3.3, 6.8); the alternative would be to suppose very complicated and highly 

 improbable vertical movements of the substratiom to explain the regularity of 

 the curves. The rhythm of these high sea-levels is around 20-30 ka, since at 

 least 330,000 years ago. (Author).

 Glaciated Estuary, Penobscot Bay, Maine," Marine Geolop:v . Vol 73, pp 215-236. 



Data from seismic-reflection profiles, sidescan sonar images, and 

 sediment samples reveal the Holocene depositional history of the large 

 (1100 km^) glaciated Penobscot Bay estuary of coastal Maine. Previous work 

 has shown that the late Wisconsinan ice sheet retreated from the three main 

 passages of the bay between 12,700 and 13,500 years ago and was accompanied by 

 a marine transgression during which ice and sea were in contact. Isostatic 

 recovery of the crust caused the bay to emerge during the immediate
