The crystal structure of a triclinic form of the copper(II) complex of 3-ethoxy-2-oxobutyraldehyde bis(thiosemicarbazone) (CuKTS) has been determined. The KTS coordinates to copper(II) as a tetradentate ligand via two nitrogen and two sulphur atoms.

On the basis of rock modes, textures, and mineralogy, unshocked crystalline rocks are classified into a dominant ilmenite-rich suite (subdivided into intersertal, ophitic, and hornfels types) and a subordinate feldspar-rich suite (subdivided into poi
