Ophiolites consist of

Question

Quizplus · Accepted Answer

Ophiolites are suites of mafic and ultramafic rocks that represent oceanic lithosphere that has been uplifted and exposed on land. They include pillow basalts, sheeted dikes, gabbros and peridotites, with occasional overlain sediments, including chert and volcaniclastic rocks. Option A is incorrect because ophiolites are not composed of sandstones or turbidites. Option B is incorrect because evaporites are not a major component of ophiolites, and the term "marine sediments" is too broad to accurately describe the typical composition of an ophiolite. And option D is incorrect because black shale and chert are not the main components of ophiolites, even though small amounts of these sediments may be present.
