Clearcreekite
Clearcreekite is polymorphous with peterbaylissite. The chemical formula of clearcreekite is Hg1+3CO3(OH)∙2H2O. It has a pale greenish yellow color and streak with tabular subhedral crystals and good cleavage on . It is transparent with vitreous luster and uneven fracture. Its density (calculated from the idealized formula) is 6.96 g/cm3. The mineral is monoclinic with the space group P2/c. Clearcreekite is an extremely rare mineral from the Clear Creek mercury mine, New Idria district, San Benito County, California. It was probably formed after the alteration of other mercury minerals such as cinnabar. The mineral is named after the locality where it was found.
==History==
In 1959, Mr. Edward H. Oyler found a strange-looking mineral in the Clear Creek mercury mine.〔Dunning, G.E., Hadley, T.A., Magnasco, J., Christy, A.G., and Cooper Jr., J.F. (2005) The Clear Creek Mine, San Benito County, California: A unique mercury locality. The Mineralogical Record, 36, 337-363.〕 More than 30 years passed until edoylerite, named on his honor, was properly described by Erd et al.(1993).〔Erd, R.C., Roberts, A.C., Bonardi, M., Criddle, A.J., Le Page, Y., and Gabe, E. J. (1993) Edoylerite, Hg32+Cr6+O4S, a new mineral from the Clear Creek claim, San Benito County, California. Mineralogical Record, 24, 471-475.〕 For more than 20 years Mr. Oyler collected minerals from the same location; deanesmithite, edgarbaileyrite, hanawaltite, peterbaylissite, szymanskiite, wattersite, and clearcreekite are among the new and unique minerals first collected by Mr. Oyler .〔 Some of the minerals share physical characteristics like color and habit but their crystal structure is completely different, as shown by X-ray powder diffraction data.〔 Clearcreekite is an extremely rare hydrous mercury carbonate mineral.〔
