THIS UNIT MAY ALSO REPRESENT INTERBEDDED LIMESTONE AND DOLOSTONE. DOMINANT LITHOLOGY IS A CALCILUTITIC LIMESTONE PARTIALLY DOLOMITIZED AND CONTAINING SMALL BROWN DOLOMITE RHOMBS SCATTERED THROUGHOUT THE CALCILUTITE MATRIX. DOLOSTONE FRAGMENTS RANGE FROM VERY PURE TO PARTIALLY CALCITIC. ALL DOLOSTONE BELOW 3130' MAY REPRESENT CAVINGS, BUT WITH THE DEGREE OF DOLOMITIZATION IN THE LIMESTONE THE DOLOMITE FRAGMENTS ARE ASSUMED TO REPRESENT THINLY BEDDED LIMESTONE AND DOLOSTONE. |
