Late- and post-orogenic Neoproterozoic intrusions of Jordan: implications for crustal growth in the northernmost segment of the East African Orogen
- G. Jarrar, R. Stern, G. Saffarini, H. Al-Zubi
- Geology
- 10 June 2003
Approximately 90% of the upper crust exposed in southern Jordan is composed of intrusive rocks of latest Neoproterozoic age, grouped into two major subdivisions: the Aqaba (600–640 Ma) and the Araba… Expand
A Pan-African alkaline pluton intruding the Saramuj Conglomerate, south-west Jordan
- G. Jarrar, H. Wachendorf, D. Zachmann
- Geology, Medicine
- 1 April 1993
The geological setting, petrography and bulk mineral chemistry of a monzodiorite and a presumably consanguineous megaporphyry with large (up to 25 cm) labradorite megacrysts, both intruding the upper… Expand
Origin, age and petrogenesis of Neoproterozoic composite dikes from the Arabian‐Nubian Shield, SW Jordan
- G. Jarrar, G. Saffarini, A. Baumann, H. Wachendorf
- Geology
- 1 April 2004
The evolution of a Pan-African (c. 900–550 Ma) suite of composite dikes, with latite margins and rhyolite interiors, from southwest Jordan is discussed. The dikes cut the Neoproterozoic calc-alkaline… Expand
The Saramuj Conglomerate: Evolution of a Pan-African molasse sequence from southwest Jordan

Geochemistry and P–T–t evolution of the Abu-Barqa Metamorphic Suite, SW Jordan, and implications for the tectonics of the northern Arabian–Nubian Shield
- G. Jarrar, T. Theye, N. Yaseen, M. Whitehouse, V. Pease, C. Passchier
- Geology
- 1 December 2013
Abstract The Abu Barqa Metamorphic Suite (ABMS) represents the oldest part of the Arabian–Nubian Shield in southern Jordan. It comprises tonalitic gneiss, metasediments including schist and… Expand
Age determinations in the Precambrian basement of the Wadi Araba area, southwest Jordan
- G. Jarrar, A. Baumann, H. Wachendorf
- Geology
- 1 May 1983
The Precambrian basement of Jordan belongs to the northern margin of the Arabian-Nubian Shield. Age determinations by U-Pb isotopic analyses on sized and magnetic zircon fractions, a monazite and an… Expand
The youngest Neoproterozoic mafic dyke suite in the Arabian Shield: mildly alkaline dolerites from South Jordan – their geochemistry and petrogenesis
- G. Jarrar
- Geology
- 1 May 2001
The Arabian–Nubian Shield evolved through a sequence of tectonomagmatic cycles, which took place during Neoproterozoic time (1000–540 Ma). Dyke emplacement constitutes one of the conspicuous features… Expand
The major, trace and rare earth element geochemistry of glauconites from the early Cretaceous Kurnub Group of Jordan
- G. Jarrar, Belal S. Amireh, D. Zachmann
- Geology
- 20 June 2000
The major, trace and REE geochemistry of glauconites (as members of the trioctahedral micas) from the early Cretaceous Kurnub Group of Jordan are discussed. The investigated glauconites, with 7.1 to… Expand
K-Ar dating, X-Ray diffractometry, optical and scanning electron microscopy of glauconies from the early Cretaceous Kurnub Group of Jordan
- Belal S. Amireh, G. Jarrar, F. Henjes-Kunst, W. Schneider
- Geology
- 1998
The glaucony of the early Cretaceous Kurnub Group in Jordan has been isotopically dated using the K‐Ar method. The glaucony occurs in an arenaceous dolomite unit, referred to here to as glaucony… Expand
A late Proterozoic bimodal volcanic/subvolcanic suite from Wadi Araba, southwest Jordan
- G. Jarrar, H. Wachendorf, G. Saffarini
- Geology
- 1 April 1992
Abstract Geotectonic setting, age relationships, petrography and geochemistry of a Pan-African bimodal volcanic/subvolcanic suite have been examined. The volcanic phase terminated the Pan-African… Expand
