Neither, at the surface all rocks become weathered.
Sedimentary rocks of weathered rock fragments are called clastic rocks.
We get weathered by being on or near the surface and exposed to environments different than we were formed in.
Detrital sedimentary rocks, also called clastic sedimentary rocks, are composed of rock fragments that have been weathered from pre-existing rocks. They are the most common rocks on the surface of the earth.

The process of moving weathered rocks and soil is called WEATHERING.
Any type of rock can be weathered. However, as the Earth started off in a molten state, the first rocks to be weathered must have been formed from magma and were therefore igneous rocks.
The process of breaking down of rocks and minerals on the surface is known as rock weathering.
They are called clastic sedimentary rocks.
Basal Surface of Weathering is also known as the Weathering Front, which is the boundary between weathered and unweathered rocks.
Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
