Granofels, a New Metamorphic Rock Name

The term granofels is proposed for medium- to coarse-grained, granoblastic, metamorphic rocks without, or with only indistinct, foliation or lineation. Existing terms such as granulite, hornfels, leptite gneiss, and leplynite gneiss are unsatisfactory for such rocks. Granofels is primarily a field name on a par with such terms as gneiss, schist, and slate. Granofels is transitional with hornfels in grain size and with gneiss in structure.
