The complex is dominated by silty bioclastic mudstones and wackestones that interbed
those debrites and turbidites.
A mudstone was silicified to form the microcrystalline silcrete: this was probably an interbed
within the Lower Jurassic sandstone.
Drilling has identified three primary sub horizontal gold zones; an upper zone at the Permian limestone/Tertiary sediment unconformable contact, a middle horizon at a marble/silty limestone interbed
and a lower zone at a volcanic lava/silty limestone contact and a fourth zone of post surface weathering/oxidation of the primary lodes (regolith) occurring in modern karst environment.
This suggests the megaripple sandstone/fine grained sandstone/siltstone interbed
sequence formed in a fluctuating shallow-marine environment characterized by fluctuating energy conditions in which deposition alternated between just below and within wave base.
europaea) caught in seed traps placed at bed and interbed
This pit is characterized by limestones, marls, cellular limestones, interbed
limestone conglomerates, undulated limestones and ore-bearing dolomites in the roof part, which are visible on the practically vertical quarry walls.
4 m based on the first indication of the Cremnoceramus waltersdorfensis species (Andert) is accentuated by a characteristic development of the carbonate curve morphology and fine sand interbed
in this footage.
Southwards they are replaced by marls with a limestone interbed
, which are probably contemporaneous with the lower part of the Prabuty marls and shales included in the Pirgu Stage in Poland (Modliniski & Szymaniski 1997).
This paper presents ages of detrital zircon grains in a quartz arenite sample from an interbed
in the conglomerate-dominated central part of the Horton Group sequence as a further step in investigating the source of the Horton Group sediments deposited in the Isle Madame area.
A lens-like conglomerate interbed
(0-7 cm), with flat pebbles of the underlying dolostone, occurs on the 3a and 3b boundary.
