Methodology for the production of film monoliths

Abstract

The article presents a method for making film monoliths, which we used in 1950 when studying the soil and ground conditions of the stadium sites of the DSO "Medic", named after V. I. Lenin in Leningrad and the City Stadium in Vyborg. We based the proposed method on some experience in making film monoliths by Professor K. Orvik and personal results of selecting monoliths at the indicated sites. The value of film monoliths for geologists and engineering geologists involved in studying the soil and ground conditions of construction sites, stadiums, etc. is obvious. Film monoliths can be of no less importance in geological mapping of Quaternary deposits represented by sandy, clayey and sandy loam rocks. It is known that when documenting sedimentary rocks with a loose structure, there is a desire to "reinforce" the sketch and description of the outcrop with samples with the most characteristic textural and structural features of these rocks, while preserving the sequence of stratification and the diversity of their color. Meanwhile, obtaining samples of loose rocks from deposits of cross-bedded sands, varved clays and lacustrine-marsh deposits is very difficult.
