| Species: | Mimetite | |
| Formula: | Pb5(AsO4)3Cl | |
| Comments: | Mimetite from Merehead exhibits a wide range of coloration, from white through yellow, green, beige, and brown to red. Invariably these all have similar chemistry, near to end-member (arsenate) mimetite. Phospate and vanadate are low to absent. Pyromorphite and lorettoite - though listed from Merehead - have not been confirmed. Several specimens so labelled were tested and all proved to be mimetite. Microscopic darker red patches in some orange mimetites found in June 2006 have V > As (approximately 7:5) and these patches are technically vanadinite (q.v.). | |
