The effects of heating and dehydration on the crystal structure of hemimorphite up to 600{u00B0}C
The crystal structure of hemimorphite, Zn₄Si₂O₇(OH)₂H₂O, has been refined from X-ray intensity data collected at 300°, 600°, and 22°C (after heating to 600°C). The space group throughout the experiment was Imm2, Z=2, and the cell dimensions at each temperature, in the above-mentioned order, are: …

A single-crystal EPR study of radiation-induced defects in selected silicates
… minerals, including apophyllites, prehnite, and hemimorphite, not only providing new insights to mechanisms of radiation-induced damage in minerals but also having direct relevance to remediation of heavy metalloid contamination and nuclear waste disposal. The NH2 free radical, which is one of …

Mineralogy and geochemistry of the non-sulfide Zn deposits in the Sierra Mojada district, Coahuila, Mexico
… consists of strata-bound zones dominantly of hemimorphite (Zn₄Si₂O₇ (OH)₂·H₂O) that fills pores in Fe-oxides. The mineralogy of the NSZ mineralization consists of smithsonite, hemimorphite and Zn clays (sauconite) associated mainly with calcite and Mn-Fe-oxides. Zn clays are abundant in the …
