- Having the structure of schist; resembling schist, or made up of a rock so designated. A schistose structure differs from that resulting from sedimentation in that the former bears the marks of chemical action in the more or less complete interlacing or felting of the component particles, and in the continual breaks or want of continuity of the laminæ, while in the latter the particles are only held together by some cement differing from them in composition, or even by pressure alone, and are arranged in a more distinctly parallel order than is usually the case with the schists. In rocks in which a slaty cleavage is very highly developed, as in roofing-slate, this cleavage is almost always quite distinct from and independent in position of the lines of stratification, and this fact can ordinarily be recognized with ease in the field. There are cases, however, in which a schistose structure has been developed in a mass of rock parallel with the planes of stratification. Also spelled shistose, shistous.

- adj. Of or pertaining to schist; having the structure of a schist.

“He thought that the schistose rocks had been deposited from the universal ocean, which, in the first stages of the earth's history, had covered the whole surface of the earth and had been as deep as the mountains are high.”
