Figure 1. Sea-level variations and Sr isotopic composition in the Riphean basin of the Baikit anteclise, Siberian craton.
1 - stromatolite limestones; 2-5 - dolomites: 2 - stromatolitic, from (a) columnar conophytic, (b) columnar branching, and (c) algal laminated stromatolites; 3 - granular oolitic lumpy pisolitic (a), oolitic lumpy intraclastic (b); 4 - (a) micritic siltitic, partly recrystallized, and (b) clayey; 5 - (a) sandy and sand-bearing, (b) silty and silt-bearing; 6 - mudstones (a) and silty mudstones (b); 7 - sandstones (a) and siltstones (b); 8 - regional hiatus; 9 - diabase; 10-12 - dolomites: 10 - least altered, 11 - moderately altered, 12 - altered; 13-15 - limestones: 13 - least altered, 14 - moderately altered, 15 - altered. Sequences: Zl = Zelendukonsky, Vdr = Vedreshevsky, Mdr = Madrinsky, Yrb = Yurubchensky, Dl = Dolgoktinsky, Km = Kuyumbinsky, Kp = Kopchersky, Yukt = Yuktensky, Tkr = Tokursky, Irm = Iremekensky. Sequence boundaries of 2nd (S) and 3rd (s) order. Sedimentary system tracts: of sea-level lowstand of 2nd (LST) and 3rd (lst) order; transgressive, of 2nd (TST) and 3rd (tst) order; of sea-level highstand of 2nd (HST) and 3rd (hst) order; early stage (ehst) and late stage (lhst) of 3rd order sea-level highstand. Maximum flooding surfaces of 2nd (MFS) and 3rd (mfs) order.
