Formation | Bed | Characteristics | Uses |
---|---|---|---|
Lower globigerina limestone | 92 | Dark stone; does not withstand exposure | Foundations and other instances where protection from the atmosphere is present |
91 | Pale yellow limestone, turns into light reddish-brown colour after some time; composed of minute fossils; easily split into thin slabs; hardens when exposed to air; weathers very well; no fossils are present except for remains of saurians etc. and a few shells | Building stone, paving stone, masonry lintels, and roofing slabs to span between masonry arches and beams | |
Lower coralline limestone | 1 | Transition (Scutella) bed; soft; often mixed and merging into the calcareous sands of the overlying stratum; fine-grained; not durable; Echini project outwards when stone decays away | Not much used in building |
