The Carnallitic Marl (15.7 m) marks the EZ3/4 boundary and is topped by the dolomitic Upgang Formation (0.6 m), the Sherburn Anhydrite Formation (6.53 m), the Sneaton Halite Formation (14.9 m), the Sneaton Potash Member (8.5 m...

... Magnesian Limestone and the Plattendolomit (as suggested by Brunstrom and Walmsley, after Borchert and Muir, 1964 ) can be argued on the evidence of fairly strong lithologic and paleontologic similarities. Given acceptance of this equivalence, Brunstrom and Walmsley’s correlation of the English Billingham...

At these shallow depths the anhydrite in these formations has been rehydrated to gypsum. Other deep boreholes around Darlington...

The base of EZ4 is marked by the Carnallitic Marl Formation, a “rotten” hygroscopic marl, a red claystone member, and a transition to a coastal plain. The Carnallitic Marls is overlain...

The hypothesis is that if ettringite is reduced, a concomitant reduction of concrete expansion and cracking will occur. If ettringite formation and concrete deterioration...
