Question:
The most commonly available minerals in the oceanic crust are:
The most commonly available minerals in the oceanic crust are:
Show Hint
Oceanic crust = mafic minerals → olivine + pyroxenes dominate.
Updated On: May 21, 2025
- clinopyroxene, orthopyroxene, olivine
- quartz, feldspar, mica
- clinopyroxene, quartz, feldspar, mica
- orthopyroxene, feldspar, mica
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The oceanic crust is primarily mafic and consists of minerals such as:
- Olivine
- Clinopyroxene
- Orthopyroxene
These minerals are typical of basaltic and gabbroic rocks that dominate the ocean floor.
