"I have learnt a great deal from this book, and highly recommend it to all those interested in Precambrian ophiolites and associated rocks, and to relevant libraries. It is full of new and synthesized data, is up-to-date on conceptual advances, and is well presented with many figures in colour.

Disrupted ophiolites occur in linear belts as much as km long between micro plates that collided during the late Proterozoic to form the Arabian Shield.

The U-Pb zircon ages and lead-isotope data from these ophiolitic rocks help constrain the history of accretion of the Arabian Shield and thereby contribute to the definition of its microplates and terranes.

ISBNAn ophiolite is a section of the Earth's oceanic crust and the underlying upper mantle that has been uplifted and exposed above sea level and often emplaced onto continental crustal rocks.

The Greek word ὄφις, ophis (snake) is found in the name of ophiolites, because of the superficial texture of some of tinite especially evokes a snakeskin. Recent developments have shown that many full and partial ophiolites are preserved in Precambrian cratons.

This book provides a comprehensive description and discussion of the field aspects, geochemistry, geochronology and structure of the best of these ophiolites.

It also presents syntheses of the characteristics of ophiolites of different ages, and an analysis of what the. Search in this book series. Precambrian Ophiolites and Related Rocks. Timothy M. Kusky. Vol Pages () Modern Analogues to Precambrian Ophiolites.

Precambrian ophiolites of Arabia: a summary of geologic settings U-Pb geochronology, lead isotope characteristics, and implications for microplate accretion, Kingdom of Saudi Arabia.

[John S Pallister; Saudi Arabia. Deputy Ministry for. The Precambrian crust of Saudi Arabia, the eastern Sudan and Egypt consists of abundant granites and granodiorites, arc-type volcanics, and well-authenticated ophiolites. The metamorphic grade is generally low.

Archaean remnants are absent. Other articles where Ophiolite is discussed: igneous rock: Divergent plate boundaries: ultramafic rocks are known as ophiolites. Many geologists believe that ophiolites formed at oceanic ridges were emplaced by tectonic forces at convergent plate boundaries and then became exposed in highly deformed orogenic (mountain) belts.

In fact, the same sequences of rocks were first reported in the. Neoproterozoic Ophiolites of the Arabian-Nubian Shield Chapter (PDF Available) in Developments in Precambrian Geology December with Reads How we measure 'reads'. Among the Precambrian ophiolites of the world (Tables 1, 2), the Arabian shield ophiolites are abundant, and are listed in more detail in Table 3, which grou ps them into oceanic and pericontin.

Ophiolites are sequences of mafic to ultramafic rock generally believed to represent ancient oceanic are distributed all across the world being all of them located at present or past orogenic belts, sites of mountain building processes.

Ophiolites are common in orogenic belts of Mesozoic age, like those formed by the closure of the Tethys Ocean. Some highly tectonized Precambrian volcanic and plutonic suites resemble ophiolites, but Penrose-type stratigraphy is lacking in pre-1 Ga sequences (Moores ).

For a recent complete review of the subject of Precambrian ophiolites, the reader is referred to the book edited by Kusky () on Precambrian ophiolites and related rocks.

Ophiolites are an assemblage of mafic and ultramafic lavas and hypabyssal rocks found in association with sedimentary rocks like greywackes and cherts. They are found in areas that have complex structure. Cross-sections simplified from R.C. Coleman,Journal of Geophysical Research, v.

86, p. Ophiolites have been found in Cyprus. Similar gold mineralization and alteration mineralogy are known in gold-bearing carbonatized peridotites (i.e., listwaenites) from various ophiolites. Carbonatized ultramafic rocks are abundant in upper Proterozoic ophiolites in three areas (Arabia, Mali, and Morocco) that were by: Precambrian ophiolites of Arabia: a summary of geologic settings U-Pb geochronology, lead isotope characteristics, and implications for microplate accretion, Kingdom of Saudi Arabia (Book).

Chilean-type ophiolites formed in a back-arc spreading zone like today's Andaman Sea. Macquarie-type ophiolites formed in the classic mid-ocean ridge setting like today's Macquarie Island in the Southern Ocean.

Caribbean-type ophiolites represent the subduction of oceanic plateaus or Author: Andrew Alden. The Ess ophiolite, one of the most important ophiolitic massifs of the Arabian Shield, consists of a lower succession of serpentinized mantle rocks overlain by an ultramafic cumulate sequence, layered and isotropic gabbros, sheeted dykes, pillow lavas and pelagic sediments.

The Ess mantle section is composed mainly of serpentinized peridotites with chromitite pods, dunite, wehrlite Cited by: 1. Much has been learned in the past 40 years about the great diversity of the internal structure and geochemical compositions of Phanerozoic ophiolites, indicating that these on-land fragments of ancient oceanic lithosphere formed in distinctly different tectonic settings during their igneous evolution.

Precambrian ophiolites are abundant in the Arabian-Nubian Shield of NE Africa and Arabia and range in age from to Ma.

In Egypt, they are widely distributed in the central and southern Eastern Desert and occur as nape complexes along sature zone or dismembered masses in metavolcano-sedimenatry assemblages. The ophiolite. The 32 research papers in this volume examine the mode and nature of igneous, metamorphic, tectonic, sedimentological and biological processes associated with the evolution of ophiolites in Earth’s history.

Divided into six sections, the book presents a wealth of new. The diagram to the right shows an cross-section of such an ophiolite. To be precise, it shows a cross-section of a vertical ophiolite, in which the layers are horizontal and the sheets are vertical.

We may perfectly well find an ophiolite lying on its side, as a result of the tectonic events that emplace it; but the relationships between the rocks remain the same. 1 Introduction. The Rub' Al‐Khali basin occupies an area of overkm 2 in southeast Saudi Arabia (Figure 1).The basin is covered by the largest contiguous sand sea in the world with dunes m or more in height [Holm, ; Edgell, ].Due to lack of bedrock outcrop (apart from escarpments on the west margin of the basin) the tectonostratigraphic evolution is known only from Cited by: OPHIOLITES 5 al manhal number three unstable and convert rapidly into hydrated magnesium silicate minerals, forming serpent-like bands with vivid green/brown colours in the rock.

Shadows over Oman mantle peridotite, January def. Ophiolite:An ophiolite is a segment of ocean crust and mantle tectonically exposed on land by obduction (overthrust), usually when an ocean basin closes.

An ophiolite sequence consists of variably altered oceanic rocks, including marine sediments, ocean crust, and part of the mantle. The name ophiolite means “snakestone” from “ophio.

Since the late s, the term ophiolite has been used to describe sections of oceanic crust and upper mantle, along with sedimentary rocks deposited on the sea floor, emplaced as thrust slices onto continental process, called obduction, results from continent-continent collision following subduction of oceanic crust and the closure of oceans or back-arc basins.
