Formation: | Garra | ||||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: Strusz interprets age as Emsian. More recent work (e.g., PBDB refs. 7152, 7167-7170) argue for age range of Lochkovian to Pragian, based mainly on conodonts. |
Lithology and environment
Primary lithology: | grainstone |
Secondary lithology: | calcareous "shale" |
Lithology description: From Strusz (1965, PBDB ref. 7170): "The two dominant lithologies are calcareous shale and detrital limestones. These are interspersed with reef-type deposits, which range from two or three rather large bioherms down to thin biostromes built by laminar stromatoporoids. The detrital limestones include all types, but are predominantly fossiliferous calcarenites, which are frequently thinly interbedded with calcareous to noncalcareous shale. In some areas there are extensive outcrops of algal limestones and pellet or oolite calcarenites; these are generally only sparsely fossiliferous." See PBDB collections 25695-25697. | |
Environment: | marine indet. |
Geology comments: 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." |
