Partially weathered bedrock is typically referred to as saprolite.

Saprolite is a soil-like material that forms in place from the weathering of bedrock. It retains the structure of the original rock but is broken down and chemically altered.

Here are some other terms you might encounter:

* Regolith: This is a broader term that includes all unconsolidated material above bedrock, including soil, saprolite, and other weathered material.

* Residual soil: This term specifically refers to soil formed from the weathering of underlying bedrock.

The specific term used depends on the context and the degree of weathering.
