The thickening Famennian sediments include organogenic limestones, dolomites with the interbedding
of clays, marls and with massive sulphate- and salt-bearing beds.
of grainstones and muddy sediments indicates the existence of spill-over lobes produced during storm conditions.
The main dam is located on quartzite's of reddish colour and with small interbedding
of silt stone of purple colour belonging to Vindhyans (Super Group).
The outcrops are predominantly red claystones placed on subordinate hard grey sandstone with interbedding
narrow beds of siliceous nodules.
The main rocks composing the massif in the profile zone are paragneiss, metabasite and their interbedding
, granite and metasedimentary rocks.
The Karki Khola Thrust zone is characterized by the sharp contrast between massive bedded 'salt and pepper' sandstones of the Middle Siwalik Subgroup and fine-grained interbedding
lithology of fine-grained greenish grey sandstone and greenish grey to purple mudstone and shale.
The seismic reflection feature with strong amplitude is possibly the comprehensive response of the interbedding
of mudstone and oil shale.
The limestone-doostone interbedding
in the section of the Volkhov Stage also indicates fluctuation in the availability of oxygen.
No fossils have been found in the Fogo Harbour Formation, but interbedding
of its lower part with the Llandovery Lawrenceton Formation fixes a maximum age, and a precise U-Pb zircon age of 422 [+ or -] 2 Ma (Ludlow) from a composite dyke cutting the formation on Dog Bay (Elliot et al.
The proportion of the area of the runoff "contributing phase" (rock outcrops) and the area of the water "receiving phase" (crevices, joints, interbedding
plans) is high.
Detachment and initial tectonic transport of rockslides on the western flank of the Sierra de la Dehesa was mainly controlled by four structural elements: 1) parallel bedded strata; 2) lateral joints; 3) interbedding
surface ruptures, and 4) layers dipping > 30[degrees], in the same direction of the slope.
Substrate (Marley with interbedding
sandstone) is located at depths greater than approximately 6.
