minerals formed by weathering

  • Weathering Clay Minerals Tulane University

    Chemical Weathering. Since many rocks and minerals are formed under conditions present deep within the Earth, when they arrive near the surface as a result of uplift and erosion, they encounter conditions very different from those under which they originally formed.

  • What types of rocks are formed by weathering? +

    Rocks are generally subjected to weathering, not formed directly by weathering. For example, a granite that is chemically or mechanically weathered will break down into the minerals quartz and feldspar which are then transported in streams (erosion) to the ocean and dumped in.
