Stratigraphy
Formation:Garra
Stratigraphic resolution:formation
Stratigraphy comments: Formation generally regarded as Lochkovian-Pragian, but much of study has been closer to Wellington, where the formation seems to be younger. Conodonts support late Lochkovian age for formation in type area. See PBDB collections 25696-25698 and refs. 7152, 7167, and 7168.
Lithology and environment
Primary lithology: lime mudstone
Secondary lithology: packstone
Includes fossils?Y
Includes fossils?Y
Lithology description: Overall the sections studied include calcarenites, calcisiltites, calcilutites, dolomitic limestone, and birdseye limestone near the top. "Beds 2 to 97 are predominantly calcarenites with some calcisiltites. Beds 104 to 512 show greater fluctuations in lithology with a predominance of calcisiltites and minor calcarenites. From bed 518 upwards calcilutites become prominent, calcisiltites subordinate and calcarenites spasmodic."
Environment:marine indet.
Geology comments: "...general pattern of fining of sediments [upward] is consistent with the hypothesized change from a shallow-water gastropod community to a deeper-water brachiopod-dominated community...These data re-enforce Talent and Yolkin's (1987) interpretation of a major transgression-regression cycle, "Garra 1", through this sequence of limestones in the Garra Formation." From Lenz and Johnson, ref. 7167: "The Garra limestones are the product of relatively shallow water deposition; the lower approximately one-third of the formation represents a progressive transgressive sequence, the middle portion is the product of still-sand and gradual infilling, and the upper one-third represents progressive shallowing to supratidal conditions."
Taphonomy
Modes of preservation:replaced with silica
Size of fossils:macrofossils
Collection methods and comments
Reason for describing collection:biostratigraphic analysis
Collection method comments: Farrell uses quantitative association analysis to recognize three communities. These are: (1) Vetotuba-Spirigerina (S.) supramarginalis Comm., beds 2-97; (2) Platyceras (Orthonychia)-Muiferella Comm., beds. 104-512; (3) Cyrtina-Ogilviella-Howellella Comm., beds 518-1196. Because these sets of beds also differ in predominant lithology, it seems naturally to amalgamate beds into three lists. Abundances given in table 1.
