LATE-EXPANSION ALKALI-REACTIVE CARBONATE ROCKS
SOME ALKALI-REACTIVE CARBONATE ROCKS OF THE ORDOVICIAN GULL RIVER FORMATION IN ONTARIO ARE CHARACTERIZED BY A SHRINKAGE PERIOD PRECEEDING EXPANSION WHEN TESTED IN 1 NORMAL SODIUM HYDROXIDE. THESE LATE-EXPANSION ROCKS HAVE A SHRINKAGE PERIOD OF AT LEAST 10 WEEKS, MAXIMUM SHRINKAGE OF AT LEAST 0.03 PERCENT, AND LATER MINIMUM EXPANSION OF 0.20 PERCENT. PETROGRAPHIC EXAMINATION SHOW THE ROCKS TO BE SANDY OR SILTY ARGILLACEOUS CALCITIC DOLOMITES. TYPICAL SAMPLES HAVE 3 TO 5 PERCENT ABSORPTION, BULK SPECIFIC GRAVITY BELOW 2.60, MORE THAN 20 PERCENT ACID-INSOLUBLE RESIDUES, AND 75 TO 87 PERCENT DOLOMITE IN THE CARBONATES. /AUTHOR/
