| Abstract: | This article briefly deals with the original environment, the division of genetic types of ophiolites, and the deformation character of the upper mantle rocks. Ophiolite can originate not only in extensive oceans but also in finite oceanic basins, marginal seas, back-arc basin and fore-arc basins. Ophiolites are divided into four major genetic types on the expanding rate of paleooceanic crust. The upper mantle rocks have undergone five deformation stages of different tectonic levels. These stages are discribed as tectonic peridotite, peridotite mylonite, peridotite breccia, serpentinite mylonite and incohensive serpentinite. |
