tivity on the carmel faul

According to Karcz (1958) there is a fault stretching from NW-SE along the upward
slope, east of Denya Cave (Fig. 7). It is estimated that displacement on this fault is less than
50m. North of the cave there is an inferred fault with a similar trend (Fig. 7). South of
Denya Cave a fault with an E-W direction is estimated by Karcz (1958) to have a throw of
50-150m (Fig. 7). In the area of exposed Mukhraka limestone the dips measured show two
different trends no more than 500m from each other (Fig. 7). Segev and Sass (2006) studied
the geology of the central and southern Carmel area and their preliminary fault map (Fig. 8)
defines two E-W trending faults in the area of Denya neighborhood; the Denya fault to the
north, along the northern slopes of the mountain spur (Fig. 6), which stretches to the east to
connect with the normal Galim fault to the south.
Circa 500m NW of the cave opening (Map Ref. Israel Grid 1485/2413) there is a
quarry where Mukhraka limestone is exposed and where a collapsed cave is quite evident,
and where speleothems can be seen (Fig. 9a,b). In that same spot there seems to be
evidence of faulting, while some of the limestone layers are tilted (~15° dip to NW; Fig.
9c). Furthermore, the collapsed cave seems to be situated on a fault plane.
Denya Cave is ca. 50m 2 in area with two main chambers. An upper chamber in which
speleothems are quite abundant is partitioned into three (Fig. 10). Throughout this chamber
evidence of collapses is seen in broken speleothems, fallen rocks and a tumbled segment of
a cave wall (Fig. 11). In a lower chamber chalk and cherts are exposed with some
speleothems found, predominantly below cracks (Fig 12). Cracks in the lower chamber
show an oblique displacement of a few centimeters (Fig.12d).
