This Christmas card from J V Harrison shows Aiuuk Bivouack in the Bakht-i-ari mountains of Persia (now Iran).
John Vernon Harrison was born on 16 March 1892. He graduated with a BSc with distinctions in Chemistry and Geology from the University of Glasgow in 1914. In 1916-1918 he served with the Royal Engineers in Mesopotamia. In 1918 he joined the geological staff of the Anglo Persian Oil Company. He carried out field work in Persia and Iraq (1918-1920) and then travelled to many places including Honduras (1920-1922), United States and Mexico (1922-1923), North Borneo, Hong Kong, Japan and Canada (1924), Peru (1924-1925), Jamaica (1925), Venezuela (1925-1926), Trinidad (1926-1927) and Colombia (1927-1928). Much of his time after 1928 was spent in Persia until he was appointed Lecturer in Geology at Oxford University in 1938. Summer vacations allowed him to travel to the Peruvian Andes with some of his students. During World War II he was seconded to the Admiralty for geographical work. After the war he was appointed Reader in Structural Geology back at Oxford. He retired in 1959, was awarded the Lyell Medal in 1961and died on 31 July 1972

Participants include John Horne, middle row, fourth from right (with moustache and prominent side-burns) Rachel Workman (later to become Lady Rachel MacRobert), middle row, third from right. Sir Alexander MacRobert is in the back row on the far right. Edward Battersby Bailey, front row, second from the right (with hat)
Rachel Workman and Sir Alexander MacRobert married in 1911.
The photograph was possibly taken before/after a trip to Sweden, Norway and Lapland in 1909/1910. The trip included a stay with the Emperor of Lapland as well as with Dr Lundbohm, originator of the Swedish Ironworks. Rachel Workman's diary also mentions a Mr. Bailey, a young Highland surveyor, we believe Bailey is front row, second from the right (with hat).
Places mentioned in Rachel Workman's diary are Narvik and the snow mountains of Torne Trask and Gellivare.
Many thanks to Vicky Duke of the The MacRobert Trust who supplied most of this information and the identification of Rachel Workman (Lady Rachel MacRobert).
Does any reader know any of the other participants or able to provide information about the background to the trip e.g. was the trip related to the 1910 International Geological Congress held in Sweden in 1910?

Sample of red sandstone, showing uniform grainsize and colour. This specimen is of Devonian age. British Geological Survey Petrology Collection sample number MC2092. This sample is from an abandoned quarry which may have been used for local building stone. Red sandstone was commonly used in Scotland from the late 19th century. The largest and most significant quarries of red sandstone in Scotland were in Ayrshire and Dumfriesshire, from where the stone was transported by railway.

Oblique photograph of a specimen of Hailes sandstone, with the name of the quarry carved on one side. This specimen is of Carboniferous age. British Geological Survey Petrology Collection sample number MC1318. The upper surface has been left in its natural state, showing the uneven bedding surface. Such samples were prepared by the quarry in order to market the stone. This sample dates from before the First World War. Size of specimen: 11x11x5 cm. Munsell colour code and colour 5YR8/1, pinkish grey.

This slate shows the trade mark stamp of the Easdale Slate Company. The specimen is of Precambrian, Dalradian age. British Geological Survey Petrology Collection sample number EMC 5736. The slate is a typical dark grey colour with a strong 'grain' and containing pyrite crystals. This specimen was donated to the Geological Survey of Scotland sometime before 1916. For hundreds of years slate was the preferred roofing material in Scotland. The geological variation found in slate quarries from across Scotland meant that each produced a characteristic slate, with a colour, texture and thickness varying from region to region.

This church with its rare but distinctive Saxon tower with a 'gabled pyramidal cap' or Rheinish Helm (Rhineland Helmet) is suggestive of early German (Saxon) architectural influence. Nevertheless it is built principally of flint nodules and local sandstones from the Weald Clay Formation. The walls of Sompting Church are built mainly of undressed flint nodules. The quoins are of a variety of rock types, some possibly derived from older buildings. The nave and transept are roofed with thin sandstone slabs from the Weald Clay. The unusual tower of this church is an important Saxon structure. Many of the churches of West Sussex were principally constructed from locally 'quarried' flints, the only suitable building stone readily available. The Rheinish Helm on top of the tower is an original Anglo-Saxon spire, the only one in the country.

Concretionary balls with calcareous cement in a sandstone of Ballagan Formation, Inverclyde Group (formerly Calciferous Sandstone Measures). This is an exceptionally large concretion which forms when minerals (here calcite but can also be silica) migrate towards a centre and concentrate into a discrete spherical body. Carboniferous strata in the Cockburnspath to Dunbar area rest on Silurian rocks of the Southern Uplands terrane and form the landward margin of a large basin which extends eastwards into the North Sea. When rocks are deformed, the concretions also deform, commonly into ellipsoids. By making an assumption about their original shape, the proportions of the deformed concretions can be used as a measure of the amount of deformation.
The Ballagan Beds is the same formation the nearby TW:eed Project were drilling while looking for 'Romers Gap'. It was a scientific research project undertaken this year to study fossils and environments from the Early Carboniferous Tournaisian Stage, roughly 350 million years ago.

Charles Lyell, Bart. born 14 November 1797.
Sir Charles Lyell, a Scottish geologist was born 14 November 1797 near Kinnordy, near Kirriemuir. He was author of 'Principles of geology', published in 1830, it was a major work at the time that supported James Hutton's view on Uniformitarianism. He was also a keen supporter of geological surveys.
The British Geological Survey (BGS) and Heriot-Watt University are joining forces to create a new centre for earth and marine science and technology. Based in Edinburgh it will be called the Sir Charles Lyell Centre and will be one of Europe's leading centres for research and expertise in the earth and marine sciences. The centre is scheduled to open by 2015.
Jointly funded by UK and Scottish funders, Natural Environment Research Council (NERC), Scottish Funding Council (SFC) and Heriot-Watt University, The Sir Charles Lyell Centre will promote innovative research at the core of geoscience, marine ecology, computing, mathematics and engineering. The Lyell Centre will create a world-leading research cluster bringing science and technology together to tackle major issues of natural resource and energy supply in a responsible and sustainable way.
Full press release on the new centre.

A fossil specimen of Cardioceras densiplicatum Boden. A fossil ammonite. (Mollusca, Cephalopoda, Ammonoidea.) 300 yards due south of Clyneleish House, Clyneleish, Brora, Sutherland, Scotland.
The genus Cardioceras belongs to the Subfamily Cardioceratinae. This specimen is from Brora, an important and well known Jurassic outcrop in East Sutherland. It is Callovian in age, which is the lowest division of the Upper Jurassic, a period marked by a marine transgression. British Geological Survey Biostratigraphy Collection number GSE 10338. Green Spot. Cardioceras is an ammonite with a moderately compressed shell, with a large outer whorl that becomes smooth. It has a strong keel and well differentiated ribs. The Cardioceratinae comprises four important genera, Quenstedtoceras, Goliathiceras, Cardioceras and Amoeboceras, they succeed each other stratigraphically with little overlap. Figd. W.J. Arkell, Mon. Pal. Soc. Vol. XCVI, 1943, pt VIII, pl LIII, fig 7; Figd. N.W. Hylland, Regional Handbook, pl XII, fig. 8.

The exoskeleton of Acernaspis can clearly be seen. It has a central axis and two side regions called pleurae. It is separated from anterior to posterior into a cephalon or head-shield, a thorax and a pygidium or tail-shield. The central region of the cephalon is called the glabella. Note the compound convex eye (like a fly's) made up of a number of separate lenses. This would give them a wide field of view forwards, backwards, sideways and upwards. The trilobites are the earliest of the arthropods. First found in rocks of Lower Cambrian age, they died out in the Permian. Throughout their 350 million year history they maintained a remarkable constancy of form, though with many varieties. All trilobites were marine. Figd. Clarkson, Elderidge, & Henry, pal. 20,plate 19, figs. 12,13.

The sandstone is fine-grained with a speckled appearance due to the presence of abundant small dark grains of iron oxide. This specimen is of Carboniferous age. British Geological Survey Petrology Collection sample number MC6198. It contains parallel bedding laminae defined by thin dark surfaces of mica and iron oxide, and distinctive red-brown banding which represents iron oxidation fronts where iron oxides in the sandstone have undergone alteration and oxidation to form vivid colours. These fronts are generally parallel to bedding, but in some places they cut across it. Such thinly-bedded sandstones were historically used for paving, they could be easily split into regular thin sizes. Quarries such as Hailes in Edinburgh provided much paving in the past for that city. Nowadays with the old quarries now infilled, stones like this from Slaley are available for repair and restoration work. Size of specimen: 10x10x7 cm. Munsell colour code and colour N8 to 10YR7/2, variable from very light grey to pale orange.
BGS have over 4300 images from the National Building Stone Collection online in the Geoscenic image resource. They can be browsed either by rock type/place or place/rock type.
