Sandstone Provenances Flashcards
Sediments are derived from volcanic-magmatic arcs formed over subduction zones along convergent plate boundaries.
Magmatic Arc Source
Contain sedimentary rocks, metamorphic rocks, and recycled volcanic-magmatic arc sediments derived from uplifted recycled accretionary complexes.
Subduction Complexes
Contain sedimentary and metamorphic rocks, of both continental and oceanic origin, uplifted during the continental collisions that close ocean basins.
Collision Orogens
Consist of diverse sedimentary, metamorphic and plutonic igneous rock assemblages exposed in orogenic belts some distance from convergent plate boundaries.
Foreland Uplifts
Sediments are derived from pre-existing, generally mature, sedimentary rocks that overlie plutonic basement rocks in a stable platform setting with very low relief
Craton Interior
Both platform sedimentary rocks and plutonic basement shield rocks are exposed as source rock types in settings of low to moderate relief.
Transitional cratons
The basement plutonic igneous and metamorphic rocks are exposed in an area of high relief resulting from uplift.
Uplifted basements
What is the setting of subduction complexes, collision orogen, and foreland uplifts?
Recycled Orogen Source
Craton interior, transitional cratons, and uplifted basements are subdivisions of what setting?
