FROST•, WAYDE MARTENS and PETER A. WILLIAMS* Inorganic Materials Research Program, School of Physical and Chemical Sciences, Queensland University of Technology, GPO Box 2434, Brisbane Queensland 4001, Australia. *School of Science, Food and Horticulture, University of Western Sydney, Locked Bag 1797, Penrith South DC NSW 1797, Australia Endnote file: boléite, laurionite, pseudomalachite ABSTRACT Raman spectroscopy has been used to characterise several lead and mixed cationic-lead minerals including mendipite, perite, laurionite, diaboléite, boléite, pseudoboléite, chloroxiphite, and cumengéite. Raman spectroscopy enables their vibrational spectra to be compared. The low wavenumber region is characterised by the bands assigned to cation-chloride stretching and bending modes. Phosgenite is a mixed chloride-carbonate mineral and a comparison is made with the molecular structure of the aforementioned minerals. Each mineral shows different hydroxyl- stretching vibrational patterns, but some similarity exists in the Raman spectra of the hydroxyl deformation modes. Raman spectroscopy lends itself to the study of these types of minerals in complex mineral systems involving secondary mineral formation. Keywords: boléite, cumengéite, diaboleite, lead, copper, chloride, phosgenite, Raman spectroscopy INTRODUCTION The use of these compounds of lead for pharmaceutical and cosmetic purposes in antiquity have been known for some considerable time (Lacroix 1911; Lacroix and de Schulten 1908).

    THE MINERALOGICAL MAGAZINE AIID JOURNAL OF THE MINERALOGICAL SOCIETY No. 174 September, 1941 Vol. XXVI Mineral localities on the Mendip Hills, Somerset. By ARTHUR W. G. KINGSBURY. [Read March 7, 1940.] THOUGH the Mendip Hills, as a district, have from time to time ~j~received the attention of geologists, details of the mineral occur- rences are, on the whole, remarkably scarce. Mining was formerly carried on on the Hills for many centuries, but mineralogy as a science had not been sufficiently developed at the time when the mines were most active, and little interest was taken in the minerals other than those suitable or required for commercial and industrial purposes. Even in later years, when, in the course of treating old refuse and tailings left by earlier miners and of various attempts to resuscitate the mining industry, much material must have been available for examina- tion, little attention seems to have been paid to it, or to the numerous quarries that were opened in the Carboniferous Limestone. Mention of a few mineral species has been made by writers from.time to time, but up to the beginning of last century, by which time practi- cally all work at the mines had ceased, the majority of accounts give little detail and were still concerned more with the commercial as~ct. Much interesting information about the old mines has been extraoted from old records and put together by J. W. Gough in his book 'The mines of Mendip', 1 but apart from a few general remarks on the minerals, he is more interested in, and treats, the subject from an historical point of view.

Khlopin Radium Institute, Roentgen Street 1, 197101 St Petersburg, Russia *E-mail: [email protected] OCCURRENCE The mineral occurs in the Torr Works (Merehead) Quarry, East Cranmore, Somerset, UK. Yeomanite is associated with mendipite, as a cavity filling in manganese oxide pods. Other oxyhalide minerals that are found hosted in mendipite include diaboleite, chloroxiphite and paralaurionite. Secondary Pb and Cu minerals, including mimetite, wulfenite, cerussite, hydrocerussite, malachite, and crednerite also occur in the same environment. Gangue minerals associated with mineralised manganese pods include aragonite, calcite and barite. Undifferentiated pod-forming Mn oxides are typically a mixture of manganite and pyrolusite, associated with Fe oxyhydroxides such as goethite (Turner, 2006).

  • Mereheadite, Pb2o(OH)Cl: a New Litharge-Related Oxychloride from Merehead Quarry, Cranmore, Somerset
    Mineralogical Magazine, June 1998, Vol. 62(3), pp. 387–393 Mereheadite, Pb2O(OH)Cl: a new litharge-related oxychloride from Merehead Quarry, Cranmore, Somerset M. D. WELCH,A.J.CRIDDLE AND R. F. SYMES Department of Mineralogy, The Natural History Museum, Cromwell Road, London SW7 5BD, UK ABSTRACT Mereheadite, ideally Pb2O(OH)Cl, is a new mineral related to litharge and which is structurally similar to synthetic bismuth-oxyhalides. With other lead- and lead-copper oxychlorides, it occupies lenses and cavities in veins of manganese and iron oxide minerals which cut through a sequence of dolomitic limestones at Merehead quarry, Cranmore, Somerset (51812’N, 2826’W). Mereheadite is pale yellow to reddish-orange, transparent to translucent and has a white streak and a vitreous or resinous lustre. It is not fluorescent. Individual grains, up to a few mm across, cluster together in compact masses of 10À30 mm in size, but discrete crystals have not been observed. Specular reflectance data on randomly orientated grains from 400 to 700 nm are provided, and refractive indices calculated from these at 590 3 3 nm range from 2.19 to 2.28. H = 3.5, VHN100 = 171, D(meas) = 7.12(10) g/cm ,Dcalc = 7.31 g/cm .The mineral is brittle with an uneven, conchoidal to hackly fracture and has a perfect (001) cleavage which is parallel to the sheets of PbO and Cl. It is intimately associated with mendipite, blixite, cerussite, hydrocerussite and calcite in lenses and pods in the veins. Other minerals which occupy cavities in these veins include chloroxiphite, paralaurionite, parkinsonite and the borosilicate datolite.

  • History and Importance of Minerals from the Mendip Hills, UK
    History and importance of minerals from the Mendip Hills, UK Mike S. Rumsey The Mendip Hills is a relatively small area in SW England near the city of Bristol (Fig.1) that is characterised by rolling limestone hills, farmland and a wealth of karstic features including caves, gorges and sinkholes. The Carboniferous Limestone here hosts a number of lead-rich mineral deposits which have been worked since ancient times and the area has a rich, but very ancient and often long forgotten mining heritage, which may, according to some explain its name - a corruption of "myne deepes" The earliest confirmed miners in the region were the Romans, who conveniently left behind a processed lead ingot, inscribed with the date AD 49. The Romans worked lead from small surface pits and might have ventured underground to find ore when the natural cave systems intersected lead rich deposits. Mining in the region was however not just limited to lead, ochre was mined from the 131h Century and copper, zinc and manganese were all extracted at one time or another. Unfortunately for scientists the vast majority of the economic mineralisation was removed from the area before the end of the 181h Century, which in the UK was just about the time when the disciplines of mineralogy, chemistry and crystallography were beginning to come together. Furthermore, around the same time, museums were becoming established and many well educated, wealthy and often powerful individuals were broadening their knowledge through the collection of objects pertaining to Natural History. As a consequence, scant mineralogical information has been recorded with regards to the early mining that went on, and very few specimens from this period are preserved within mineral collections for physical study.

The structure has been refined by the method of least squares from three- dimensional Mo-Ka intensity data to a conventional R value of 0'II5. The structure consists of sheets of com- position [Pb.

The structure contains eight-fold PbO.Cl. and seven-fold I'bOsCI. polyhedra common in other oxy- chlorides, Pb. clusters and copper atoms in square planar, Cu(OH)., coordination. CHLOROXIPHITE was first described by Spencer and Mountain (1923). In this description the perfect and distinct cleavages were assigned the indices (001) and (100), respectively, resulting in a {3angle of 62'75°. In Dana's 7th edition (1944) the crystal was reoriented with the perfect cleavage becoming (10 I) giving a {3angle of 97'79°. The crystal structure was determined on the basis of this orientation although Spencer and Mountain's original orientation could have just as well been used. The structure as determined verifies Mountain's original chemical analysis as well as the reformulation in Dana, which was marked with a question mark.
