Eclogite parent rock

Parent Rocks and Protoliths. Hornfels is not a rock that is "deposited". Instead it is a rock type that forms when an existing rock is metamorphosed. The original rock that was metamorphosed is usually referred to as the "parent rock" or "protolith".

Solid rock can Eclogite petrography. A set of thin section images, all at the same scale (1.5 x 1 cm) showing the range of textures to be found in metabasic eclogites from several different terranes, plus a few other associated high-pressure rock types. If a low geothermal gradient was present, such the one labeled "C" in the diagram, then rocks would progress from zeolite facies to blueschist facies to eclogite facies. Thus, if we know the facies of metamorphic rocks in the region, we can determine what the geothermal gradient must have been like at the time the metamorphism occurred. For all other rocks—eclogite and peridotite—the calculated fast and slow shear-wave velocity structures are more complex than their compressional-wave counterparts. It is clear, therefore, that coaxial 3-D compressional- and shear-wave velocity structures require (1) abundant highly anisotropic phase(s) with coaxial 3-D compressional- and shear-wave velocity structures and (2) an otherwise The original rock that was metamorphosed is usually referred to as the "parent rock" or "protolith".
