The Jordan Rift Valley
A New Book by Professor A. Horowitz
The book presents a synthesis of almost 150 years of research along the Jordan Rift Valley, where tectonics and climate variations
have interwoven to create a succession of natural landscapes, inhabited by changing communities of plants, animals and Man. The
complex geological and environmental evolution since its inception in the Oligocene are expressed in a variety of sedimentary and
magmatic rock units, preserved as continuous sequences in the deeper basins, where they have been penetrated by drillings,
palynolgically analyzed and radiometrically dated. The outcropping formations encircling the basins represent alternating deposition
and erosion phases, both of which are discussed in detail.
Based on a wealth of old and newly acquired data, a novel approach is presented in a model explaining the tectonic evolution of this
part of the Syrian-African Rift Valley, which may change our views regarding the geotectonic pattern of the entire western Levant.
Different views are also brought for comparison. Datings and paleoenvironmental reconstructions are provided for all important phases
in the history of the Jordan Valley. Particular attention is given to the last two million years, when numerous habitation sites
indicate the region was continuously populated.
