The Indus Suture Zone, also locally called the Sumdo Formation, contains the well-preserved Nidar ophiolite and the Zildat Ophiolitic Melange. |
|
Oceanic sediments on top of the basalts crop out on the northern margin of the ophiolite. |
|
We believe that many Mesozoic and Cenozoic obducted ophiolite belts of SE Asia are fragments of fore-arc or back-arc lithosphere. |
|
If this model does survive those tests, it has important implications for the tectonic environment in which the Troodos ophiolite formed. |
|
These felsic rocks are contemporaneous with or only slightly younger than rocks from the Guevgueli ophiolite. |
|
The Northland ophiolite crops out at headlands to the east and west of Cooper's Beach on the eastern Northland Peninsula. |
|
Previously, there has been disagreement over the direction of obduction of the ophiolite and the vergence of structures. |
|
The model therefore ignores the effects of any horizontal loads that might arise as a consequence of ophiolite emplacement. |
|
In the Beysehir region, kilometre-sized blocks of fusulinid-bearing Permian limestone occur directly beneath the ophiolite. |
|
The Dzag schists to the north of the ophiolite zone have previously been interpreted as part of an accretionary wedge. |
|
It seems unlikely that an ophiolite fragment 300 km long would remain intact and unmixed with the rest of the rocks in an accretionary wedge. |
|
The lowermost rocks are serpentinized dunite and harzburgite, which are best exposed in the NE of the ophiolite. |
|
Sporadic outcrops of ophiolite lithologies are surrounded by shale and limestone. |
|
Late Cretaceous obduction of ophiolite complexes onto the Indian shield has also been reported from Pakistan. |
|
Here the Papua New Guinea continental crust appears to be underthrusting the adjacent marginal basin and obduction of the ophiolite is occurring in an uphill direction. |
|
The contemporaneity in ophiolite formation and felsic arc magmatism suggests that intraoceanic subduction started soon after the opening of the ocean basin. |
|
The Northland ophiolite of northern New Zealand comprises massifs of mainly basaltic volcanic rocks, which form the upper thrust slices of the Northland Allochthon. |
|
The ophiolite contains a complete igneous stratigraphy of serpentinized ultramafics, gabbro, sheeted dykes and pillow lavas, as described by Moores. |
|
In this interpretation, the Troodos ophiolite formed to the east of a ridge-transform ridge intersection, in which the transform had a dextral offset and sinistral slip. |
|
Thus, periodic pressure changes result in the light-and-dark banding observed in ophiolite gabbros. |
|
|
Modeling of gravity and magnetic data along the fault has confirmed the presence of an extensive ophiolite suite. |
|
Geochemical fingerprinting of oceanic basalts with applications to ophiolite classification and the search for Archean oceanic crust. |
|
The models generated from magnetic data suggest that the ophiolite is only slightly displaced vertically by the fault. |
|
This piece of the Hajar Mountain, between Oman and UAE, is the biggest exposed ophiolite complex in the world. |
|
The peridotite unit rocks are the most altered part of Noorabad ophiolite including dunite, harzburgite and lherzolite. |
|
Ongoing accretion at a subduction zone, and the obduction of intact ophiolite slabs, are not considered to be collision. |
|
The high Zagros unit has three separate subunits, which consists of the Biston limestone, the Kermanshah ophiolite, and the Bakhtaran radiolarite. |
|
The geology of the Lizard peninsula is unusual, in that it is mainland Britain's only example of an ophiolite, a section of oceanic crust now found on land. |
|
The Dalradian metasedimentary rocks are overlain by an obducted ophiolite that is continuous for at least several kilometers on either side of the Highland Boundary Fault. |
|
The most distinctive feature is the ultrabasic ophiolite, peridotite and gabbro on Unst and Fetlar, which are remnants of the Iapetus Ocean floor. |
|
The wooded peak ofTroodoscomprises the deepest layer of a section of oceanic crust, or an ophiolite complex that was formed 90 million years ago, 8,000 metres below sea level. |
|
In northwest Turkey, the Izmir-Ankara-Erzincan suture and ophiolite zone is considered to be lithospheric remnants of the northern branch of Neotethys. |
|
The Semail Ophiolite belt has been found to contain clusters of relatively high grade copper deposits. |
|
The sessions included five main themes namely oil, deposit rocks, geology of the Arabian Peninsula, Ophiolite rocks, water resources and environmental geology. |
|
From north to south these are the Kyrenia Terrane, the Circum-Troodos sedimentary succession, the Troodos Ophiolite complex, and the Mamonia Complex in the south-west. |
