Documentation of data type mapping from Parquet to Fabric mirroring?

Is there documentation of the data type mappings from Parquet in the OneLake landing zone to Fabric mirroring?

That says "Simple parquet types are supported in the landing zone," but nothing about what those types are, or how they're mapped to Fabric data types.
