2.8b Questions (continued)

(2) What is the reaction that most likely occurs across the Grt Zone - St Zone boundary? Use the assemblage change from sample DC-01 (Bt-Chl-Grt) to sample DC-11 (Bt-Grt-St)to guide your answer?
Pick one and press "Enter".
(a) Grt = St + Bt
(b) Grt + Chl = St + Bt
(c) Cld = Grt + St + Bt
(d) Cld = Grt + St + Bt
(e) Cld + Grt = St +Chl
