Weathered rock fragments are known as sediment.
That would be "sedimentary rock". Sedimentary rock is formed from the accumulation and compression of sediments, including fragments of igneous rock that have been weathered and eroded.
The most common means of transporting weathered rock fragments down slopes is through mass wasting processes such as landslides, rockslides, and debris flows. These processes involve the downslope movement of material due to the force of gravity and are often triggered by factors such as excessive rainfall, erosion, or human activities.
Weathered rock fragments in the soil profile are the result of the breakdown of parent rock material due to physical, chemical, and biological processes. These fragments add to the mineral content of the soil and contribute to its overall composition and fertility. They play a role in providing stability to the soil structure and influencing its drainage and water holding capacity.
Sedimentary rock formed from rock fragments is called clastic sedimentary rock. These rocks are made up of pieces of other rocks that have been weathered, transported, and then deposited and cemented together. Examples include sandstone, shale, and conglomerate.

Sedimentary rocks made of weathered rock fragments are called clastic sedimentary rocks. These rocks are formed from the accumulation and cementation of fragments that have been weathered, eroded, and transported from their original source. Examples include sandstone, shale, and conglomerate.

It would have to be weathered & the fragments cemented together.
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
Heaps of frost-weathered rock fragments are known as scree or talus. They form when frost action causes rocks to fracture and break apart, creating a loose accumulation of debris at the base of cliffs or steep slopes. Scree can be found in mountainous and glaciated regions.

The rock and mineral fragments in soil come from the breakdown of parent rock through processes like weathering and erosion. Over time, physical, chemical, and biological factors contribute to the decomposition of rocks into smaller fragments that make up soil.
