The Languages of Loess

 Look out for generalizations- mostly kept under control but occasionally escaping and behaving irresponsibly.  Loess is a Chinese phenomenon- found all over the world but at its biggest and thickest and most impressive in China.  Loess is a critical part of the Chinese landscape and the first writing about Loess must have been in Chinese. As Chinese is promoted as a World language perhaps more of these early writings will become accessible and available.  A digression already- this is the age of the Chinese language; all made possible by the coalscence of the language and advanced computer technology- read 'Kingdom of Characters' by Jing Tsu, published by Penguin in 2019.

"Computers are finally able to process Chinese! Long live square characters."  Chen Mingyuan 1980

The marriage of computer + Chinese language may lead to all sorts of remarkable and marvellous effects and will surely result in increased publication in Chinese, about Loess. But this is for the future. This discussion is essentially historical.  Scientific writing about Loess was initially a European affair.

Rogers CDF  Dijksra TA  Smalley IJ  1994  Hydroconsolidation and subsidence of loess: studies from China, Russia, North America and Europe- in memory of Jan Sajgalik.  Engineering Geology 37,  83-113

Why this EG reference; what is the relevance of hydroconsolidation?  It has been claimed that this is the first paper to give some consideration to the five loess languages: Chinese, English, German, French, Russian- the five languages in which most papers on loess are/were published. Loess soil structure collapse is a problem on all continents- a practical problem considered in all local languages- and all international languages. Andre Dodonov once remarked that 90% of loess research in the Soviet Union was devoted to the study of collapse and subsidence- which is not really a surprise when one considers the coincidence of population and collapsing loess ground in the east of the country. Much loess research was published in Russian- collapse studies reviewed in Rogers et al (1994). There were always transmission and translation problems- right to the end of Soviet times the term 'collapsibility' caused problems and much Russian work was not appreciated because of this single problem.

Kriger probably remains the key person in Russian loess bibliography. Nicolai Ivanovich Kriger- a much published but little appreciated star of the literature in Russian. Actually having stated that it must be noted that Marton Pecsi, during his years as President of the INQUA Loess Commission, did work closely with Kriger, and their joint efforts served to promote interest in Loess in Russian.


N.I.Kriger (photo taken at the time of the IGC in Moscow in 1982 (by IS). It appears to be the only photograph of Kriger extant, various searches have not revealed another; also it would be useful to know his dates and something of his history. From the bibliographical point of view the most useful Kriger work is Kriger 1965 the book he produced for INQUA  at Boulder USA in 1965.


Kriger, N.I.  1965.  Loess- its characteristics and relation to the geographical environment.  pub. Izd-vo Moscow 296p. (in Russian).  Only 1350 copies of this invaluable work were printed and they are extremely scarce. It is a particularly useful book because of its bibliographical content. There must be other relatively large scale studies of Russian loess (loess in Russian) but none appears to rival the Kriger volume. Sections of Kriger 1965 were reprinted in Loess Letter Supplements but these were not widely circulated and are probably as rare as the original. 


German

The Rhine Valley; for a long time for the OED the home of loess. The first European writings on loess were in German

Slobodan Markovic goes to LoessFest 1999

 In 1824 Karl Caesar von Leonhard defined Loess in volume 3 of his great work : Charakterstik der Felsarten. That was a beginning for loess studies.  1999 was just about the 175th anniversary of that remarkable loessic event and a conference was held to mark the occasion. It was held in Heidelberg and Bonn and was the largest and most ambitious Loess conference ever attempted. It was organised by Edward Derbyshire, Ian Smalley & Ludwig Zoeller.

ED made enormous efforts to raise funding so that distant scholars could attend, and as a result there were loessic contributions from far and wide; it was a truly international meeting and the conference part, in Bonn, was beautifully housed and organised. IS was secretary of the INQUA Loess Commision at that time and had access to a small amount of INQUA funding. ED suggested that this funding should support an applicant from Serbia who deserved some assistance- so INQUA support was provided. This applicant was of course Slobodan. Many years later ED was heard to observe that ' never had INQUA funds been better deployed'  it might be claimed that loess scholarship took a great step forward (or similar extravagant claims may be made). SM participated in the 1999 INQUA LoessFest; it was a memorable occasion..

Thermogravimetric Analysis of Essex Loess

 A new review shows the extent and nature of the UK and Irish loess; this note is designed to complement that excellent compiliation- it concerns the loess in south east Essex

C.Bunce, T.Stevens, I.Smalley, A.Assadi-Langroudi  2022   Loess in Britain and Ireland; formation, modification and environmentsl significance, a review in memory of John Catt 1937-2017.  Proceedings of the Geologists Association




The loess is concentrated in the south-east of the county, near to Southend on Sea. The Greater Essex Mineral Resource map shows the location with reasonable precision.



Grenville Lill managed to obtain brickearth samples from the Star Lane and Cherry Orchard Lane brickworks. These were possibly the last two brickearth producers in Essex. As far as we know the only substantial TG analysis on London Brickearth was carried out on these samples.

LL65: Notes for a History of INQUA


 The history of INQUA which was presented in LL65 (April 2011) can be accessed in two places: on the official INQUA website- the LL history has become the official history- go to www.inqua.org>about>history, nicely laid out but lacking pictures. If you want the pictures of the logos etc go to the Michigan State University presentation of the whole collection of LL and call up LL65: loessletter.msu.edu. If you have access to an original hardcopy of LL65 preserve it- no doubt it will become a bibliographical treasure.

The P.D.Tilley map of the loess in southeast England

 Colin Bunce has produced a new version of the map which P.D.Tilley presented at the 1961 INQUA meeting in Poland. Tilley participated in the Loess Symposium organised by Julius Fink. The new map supplements the new paper on the loess in Britain and Ireland by Bunce et al (2022). in Proc.Geol.Assoc- available online- should appear in hard copy in the October issue of PGA.

Ian Lindsay Freeman b.1927

 Ian Lindsay Freeman, b.1927, probably in Dundee; joined the Building Research Station in Garston, Watford in 1962; retired in 1980s.


 This is the hypothesis: That the ILF paper on the mineralogy of ten British brick clays, published in the Clay Minerals Bulletin in 1964, is the best available listing of the mineralogy of British brick making materials. No other readily available source of mineralogical data is apparent. ILF sample 63AH gives an analysis of a London Stock Brick mixture- one of the very few to give any information on this important source of bricks; bricks made from the loess of south-east England.

The interest in the work of ILF arises because of the connection to the 'Loess in Britain' project. Acknowledgements for assistance go to: Dave Morgan, the Mineralogical Society, Monica Smalley. Picture from the BRE publication Building Magazine 11 June 1971 pp.69-70
