They are light to dark-grey, fine to medium-grained, hard, compact and thin to medium-bedded and at places thick-bedded
. The algal stromatolites and laminations are the common features.
Description and interpretation of the facies identified across the Jupiter-Chicotte formational boundary in the Jumpers section Facies Composition Description FA-3 Almagamated Pack/ Packstone/ encrinites (1) grainstone grainstone: Medium- (100%) to thick-bedded
This unit consists of thick-bedded
limestone with low weathering tightly between layers of radiolarian.
The successions show coarsening upward trend with gradual increase in the deposition of sandstone towards top, and finally overlain by a thick-bedded
, trough cross-stratified, coarse-grained sandstone facies.
The overlying Cerro La Espina (CLE) Member is composed of very thick-bedded
bioclastic packstone-grainstone and thick- to medium-bedded grainstone and packstone.
It consists of thick-bedded
, greyish green to purple, quartz pebble to cobble conglomerate that contains conspicuous clasts of mafic volcanic rocks derived from the plagioclase-phyric flows of the underlying Long Island Bay Formation of the Grand Manan Group.
The territory can be characterized by the relief of the thick-bedded
sandstones with unrivalled varieties of meso-forms of weathering and erosion of sandstones.
Adjacent to the biohermal limestone area, the Lumanda quarry and Moldri core (depth 29.8-38.4 m) exhibit predominantly medium- to thick-bedded
, wavy or horizontal fine-grained skeletal grainstones alternating with pelletal packstones and skeletal wackestones.
The overlying Lumshiwal Formation is thick-bedded
dolomitized sandy limestone.
150): thickness < 0.2 cm = microbedded, 0.2-2.0 cm = thin-bedded, 2-10 cm = medium-bedded and 10-50 cm = thick-bedded
- Alternation of dolomite and thick-bedded
Limestone containing pellet, ooid, intraclast
Generally, the territory has a typical relief of thick-bedded
sandstones of the Czech Cretaceous Basin with an unusual variation of weathering forms and removal of sandstones (Balatka and Sladek, 1984).
