Inversion (geology)
Relative uplift of a sedimentary basin or similar structure as a result of crustal shortening / From Wikipedia, the free encyclopedia
In structural geology inversion or basin inversion relates to the relative uplift of a sedimentary basin or similar structure as a result of crustal shortening. This normally excludes uplift developed in the footwalls of later extensional faults, or uplift caused by mantle plumes. "Inversion" can also refer to individual faults, where an extensional fault is reactivated in the opposite direction to its original movement.
Not to be confused with inverted relief.
The term negative inversion is also occasionally used to describe the reactivation of reverse faults and thrusts during extension.
The term "inversion" simply refers to the fact that a relatively low-lying area is uplifted ā the rock sequence itself is not normally inverted.
