Comparison of Tidalites in Siliciclastic, Carbonate, and Mixed Siliciclastic-Carbonate Systems: Examples from Cambrian and Devonian Deposits of East-Central Iran

Table 3

Comparison of architectural elements and their interpretation in three tidalite systems.

Architectural element	Code	Lithofacies assemblage	Geometry and relationship	Sedimentary environment
(I)
Channel deposits	CH	Gcm, Gms, Gt, Sp, St, Sr,; Sl, Sh, Se, Fl	Erosional base; wedge shaped (laterally less than 50 m)	Tidal channels in intertidal and subtidal settings
Lateral-accretion macroform	LA	Sp, St, Sr, Sl	Erosional base; lense shaped	Meandering (ebb channels), in intertidal setting
Sandy bedforms	SB	Sp, Sl, Sh, Sr, Sm, Fl,; Sr(Fl), Sr/Fl	Sheet and blanket shaped	Sandy flat in intertidal setting
Muddy sets	FF	Fl, Fl(Sr), Sp, Sr	Laminated mudstone with sandstone lenses	Supratidal setting
(II)
Channel deposits	CH	Dim, Dp, Dr, Dsd, Dsp,; Dl	Erosional base; wedge shaped (70 m up to 100 m)	Tidal channels in intertidal and subtidal settings
Carbonate bedforms	CB	Dr, Dsd, Dsp, Dl, Dr/Fl,; Flc	Sheet and domal shaped	Intertidal setting
(III)
Channel deposits	CH	St, Sp, Sr, Sl, Sh, Se, Ds	Erosional base; wedge shaped; (40 to 80 m)	Tidal channels in intertidal and subtidal settings
Lateral-accretion macroform	LA	Sp, St, Sr, Sl	Erosional base; lense shaped	Meandering (ebb channels), in intertidal setting
Sandy bedforms	SB	Sp, Sl, Sh, Sr, Fl, Sr(Fl), Sr/Fl, Ds, Dl	Sheet and platy shaped	Sandy flat in intertidal setting
Muddy sets	FF	Fl, Fl(Sr), Sp, Sr, Sh, Sr/Dl	Mudstone laminated with sandstone lenses	Supratidal setting
Evaporate-muddy sets	EF	El, Efl, Efm, Edl	Evaporate layers with laminated mudstone	Upper supratidal and sabkha settings
