Summary:
At the time of writing, the Clover Creek Greenstone was in the process of being elevated to group rank and subdivided into two new formations, the Harsin Ranch and the Tucker Creek Formations of Permian and late Triassic ages respectively. Names and classification credited to Koch and Bowen (1962, written commun.).
Type locality and derivation of name not stated.
[As of 2006, these revisions have not been published. And, no references in GNC index card files to indicate usage since 1962. Harsin Ranch Formation therefore considered invalid and obsolete.]
