The island consists of a granite base and a calcarenite mantle; its margins steeply over-hanging and eroded.
12.
The spur is composed of yellowish calcarenite over a marl basement, all formed in the Miocene as a sea bottom.
13.
Short-tailed shearwaters and white-faced storm petrels nest in burrows excavated within the soil on the island s calcarenite cap.

The term calcisiltite was not an original part of the calcilutite, calcarenite and calcirudite classification system for limestones, which Grabau proposed in 1903.
15.
In Paleogenic layers function Liburnijska and alveolinic-nummulitic limestones, then eocenic flysch, which is represented by marl, sandstone, calcarenite and conglomerates.
16.
The Sinbad member consists of three layers : the basal, fossil bearing unit, the middle calcilutite part, and a top dolomitized calcarenite layer.
17.
The top of sediment included fossil-rich calcarenite and calcium-rich mudstone and siltstone, indicating a shallow-water setting at the time of deposition.
18.
A remnant cap of calcarenite still exists over the eastern half of the North Islet while the South Islet has lost its calcarenite cap due to wave action.

20.
In the eastern area, the amber is found in a sediment formation of organic-rich laminated sand, sandy clay, solvated beds of gravel and calcarenite.
