Roof pendant geology.
The presence of roof pendants indicates that the igneous body is being observed near its upper surface.
Cretaceous granite intruding cambrian metasedimentary rock sierra nevada range.
They are exposed by erosion of the overlying rock.
In lay terminology sometimes rock hat is used.
These older rocks that are intruded by the granite are called roof pendants because they show the roof of the batholith.
The dinkey creek roof pendant includes schist quartzite hornfelds calc silicate rocks and marble.
In structural geology a roof pendant which also known as a pendant is a mass of country rock that projects downward into and is entirely surrounded by an igneous intrusion such as a batholith or other pluton.
