Definition
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix
Trachyandesite is an extrusive igneous rock.

Etymology
From the mountain ranges- Mount Kenya and is named by J. W. Gregory in 1900
From French trachyandésite, trachy + andésite andesite, a lava intermediate in composition between trachyte and andesite

Formation
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
