Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Christian Leopold von Buch

From German Troklotit, from Greek trōktēs, a marine fish (taken to be trout)
