Thomas Becker of the Geological Survey of Namibia introducing the geology
of the Rehoboth district |
 |
Oanob Dam Resort is built on deformed acid metavolcanics of the Langveld
Formation |
 |
Deformed polymictic conglomerates at the base of the Langveld Formation,
highway cutting just outside Rehoboth |
 |
Secondary oxidised copper staining on outcrop of Klein Aub Formation,
Klein
Aub copper mine (now closed) |
 |
Thunderstorm building up over the Rehoboth basement inlier, near Kobos |
 |
View NW from the top of Spreetshoogte Pass; basal Damaran sediments
in the distance, light grey Grauwater Formation quartzites within theAreb
shear zone in foreground |
 |
Sinclair-age acid volcanics build the Rotter Kaum escarpment, between
Solitaire
and Sesriem |
|

SOSSUSVLEI
Anybody tripping through the Pre-Namib mountains will not be able to
resist the lure of the magnificent sand dunes, particularly those accessible
via the Tsauchab-Aub river corridor, below Sesriem |
 |
Namib dune north of Sossuspoort, where the 2WD track to Sossusvlei crosses
the Tsauchab River |
 |
Dune 45, on the south side of the Tsauchab-Aub corridor to Sossusvlei |
 |
Northern continuation of Dune 45 |
 |
Dunes and vegetation along the northern margin of Sossusvlei |
 |
Southern margin of Sossusvlei |
 |
Northern embayment of Sossusvlei |
 |
Dead Vlei, cut off from Sossusvlei to the south by advancing dunes |
 |
Complex dune NW of Sossusvlei (note group of people on low dune crest
in
lower right) |
 |
High dune NW of Sossusvlei |
 |
High dune NW of Sossusvlei (note group of people on low dune crest
at right
foreground) |
 |
Dunes advancing over ancient lake beds, SW of Sossusvlei (note
people ascending
the dune in left foreground) |
 |
Dunes closing in to the west of Sossusvlei |
AWASIB MOUNTAINLAND
Part of the Namib Desert Park south of the Tsauchab River that is practically
inaccessible and visited by permit only |
 |
View west from Chowachasib Mountain across boulder fields towards outcrops
of the Tertiary Tsondab Formation, semi-consolidated bedded dune and alluvial
sands buried under the Recent sand sea |
 |
Tsondab Formation bedded sands overlain by Recent dunes, west of Chowachasib
Mountain |
 |
Haiber Hill, view over outcrops of Kairab metasediments to the Haiber
Flats |
 |
Urusib Mountain, view west over outcrops of conglomerates and quartzites
of the Urusib Formation |
 |
Massive talus fans spill out from Awasib Mountain, built of acid and
basic
lavas of the Sinclair-age Haiber Flats Formation |
 |
Thomas Becker and his constant companion hammer, on acid volcanics of
the
Haiber Flats Formation, Awasib Mountain |
 |
Low setting sun shadows on sandy talus at the base of Awasib Mountain,
overlooking the Haiber Flats in the distance |
 |
Black manganiferous desert varnish coat boulders of monzogabbro, Saffier
intrusive suite |
 |
View NW from Sonop towards Satanskop, built of Chowachasib granite |
 |
Rose quartz and dark chlorite develop comb-style banding in veins bearing
copper, Sinclair Mine (now closed) |
 |
View SW from Sinclair Mine towards alluvial fans rendered green due to
recent rains |
 |
Gently dipping sediments of the Kunjas Formation unconformably overlying
acid volcanics of the Nagatis Formation |
 |
Fine scale banding in calc-silicate metasediments (interbedded chert
and
dolomite), Groot Karas Mountains |
 |
Mafic dykes of the Gannakouriep swarm form ridges near Klein Karas |
 |
The Fish River Canyon has cut through the Nama plateau, revealing basement
gneisses of the Namaqua Province |
 |
Migmatites of the Namaqua Province are exposed deep in the Fish River
Canyon,
beneath horizontal Nama strata |
 |
Complex multiple intrusion is exposed in the side canyons leading down
to Ai-Ais; metagabbros of the Ai-Ais Complex are cut by grey gneissic granite
and then by dykes of pegmatite and rose quartz |
 |
View west from the Haib River, over the Tsams farmhouse ruins towards
mountains
containing copper porphyries |
 |
Klondyke steep structure, Okiep copper district; shallow-dipping foliation
in Nababeep gneiss is locally steepened |
