Ophiolite rocks are heaviest rock in the crust but they are found on the high mountain due to obduction. Their heaviness is against isostatic theories because these theories clearly indicate that high mountain must be comprised of light rocks. Therefore the ophiolite obduction and its occurrence on high mountain is strongly suspicious. My recent researches, in Iraqi Zagros, proved that what are called ophiolite rocks are metamorphosed greywackes ( impure sandstones)
This question is based on incorrect information. Ophiolites occur as extended accretionary terranes in the continental crust. Their presence in depressions or mountains depends on the orogenic process that follows accretion. For example, most Paleozoic ophiolite belts in Central Asia are 85-90% in depressions and are covered by a Mesozoic sediment cover. However, in areas of active modern orogenesis, such as the Pamirs, ophiolite terranes have been found at altitudes of up to 5 km or more.
Pavel Mukhin You do not understand my question, which refer to its disagreement with isostasy theory because they are heavies rocks in the crust, so they must not be found on high mountains such Zagros and Alps, therefore, either isostasy theories are wrong or ophiolite obduction, please speak about this discrepancy between ophiolite on high mountain and isostasy which indicate that high mountains must comprised light rocks to compensate their roots
Ophiolite rocks talk in high mountains due to the processes of Earth's formation, which include the collision of tectonic plates. During the initial collision of plates, ophiolite rocks are formed as a result of the fusion and mixing of the continental and oceanic crusts, leading to the uplift of these exotic rocks in mountainous areas. Although they are heavy, the powerful geological forces that lead to mountain building can elevate them to great heights.
Kamal H Karim is not accepted my reply, which explains that ophiolite appearence in the uplifted parts of orogenic mountains caused by collision and uplift. Isostasy can not be applied for that enviroment. It is clear from his question and comments, we speak different languages, and I wish him success!
Pavel Mukhin all mountain are uplifted by collision or tectonic forces, isostasy theory developed for mountain that are collisional and has roots deep in the earth such as Himalaya, Alps and Zagros, they are now balanced (nearly stable) due to principle of Isostasy and ophiolite is totally against isostacy theory ( isostasy theory not developed for flat regions or stable continents but for mountain regions)
