DEIR EL-BAHARI
EGYPT
The limestone here contains many
horizons of flints, which are present in the
form of elongated modules. The limestone
reveals a macroscopically homogeneous
texture and a not-orientated structure. The
direction of the best cleavage is parallel to
the layers. This feature made cutting in the
limestone relatively easy.
Determination of grain size composition
of slope taluses was conducted at geological
sections nos. I-IV.
Section I was located about 15 m to the
east of the “niche”. The destroyed slope
talus here contains clay minerals. Section II
reveals typical slope sedimentation. It is
located under a big block of limestone,
about 25m east of the “niche”. Observation
and granulometric analyses both showed
increasing grain size from section top to
bottom. The third section is located in
a 5 m deep pit, about 35 m to the south of
the “niche”. Big blocks of limestone can be
observed at the top of the section. Below
the size of material is reduced. Finally,
section IV, just about 5 m south of the
“niche”, where the sequence of slope
sediments was tested.
Examination of the sections disclosed the
presence of two genetic types of stones, i.e.,
natural and chipped. Grain-size analyses of
talus sediments were performed every 0.5 m
starting from the top of the sections. The
obtained data will be calculated and
presented in a separate publication.
Theban limestone and fine talus
sediments were collected for mineralogical
examination. Small fragments of chipped
flakes of limestone were taken for analyses
and comparison with limestone from the
cliff. The fine clay material will be
examined for its genesis and for similarity
to either the Esna shales or Nile silt.
