‎Soft cover : The book was rebound, retaining the damaged original front cover. 25,5 x18,5 cm, 115 + 100 pp., English, 1st Edition, Illustrations: All the illustrations (15) and figures (16) are present, book condition: Very Good. This is a foundational geological study published in 1920 by Liangfu Ye (also cited as L.F. Yih). rnPublished as the first volume in the Memoirs of the Geological Survey of China (Series A, No. 1), the work represents a critical early effort by Chinese scientists to systematically map and describe the region's stratigraphy and mineral resources. rnKey Details of the Publication:rnAuthor: Liangfu Ye (L.F. Yih).rnPublisher: Geological Survey of China, Ministry of Agriculture and Commerce.rnContent: The 115-page memoir includes detailed descriptions of geological formations, 15 plates/maps, and 16 figures. It features a bilingual format with a summary and significant sections in Chinese.rnScientific Contribution: Yih identified the Hungniiaoling Sandstone Series(Hongmiaoling) as a transitional sequence between the Palaeozoic and Mesozoic eras, a classification that remained influential until later fossil discoveries in 1927.rnScope: The study focuses on the Western Hills (Xishan), a mountain range that covers roughly 17% of the Beijing municipality and is vital for its coal-bearing formations, such as the Mentougou. rnThe second part of the 1920 memoir is the rnChinese translation and supplement, which mirrors the English text but provides essential context for the local scientific and mining community of the time. rnWhile the first 115 pages are in English, the latter portion consists of approximately 100 pages written in Chinese (using traditional characters and Chinese numerals). This section was not just a summary, but a comprehensive formal record intended to establish standardized Chinese geological terminology. rnKey Components of the Chinese Section:rnGeological Terminology: It was one of the first major works to formalize Chinese names for strata and rock types. For example, it solidified terms for the Sinian formation (???), igneous rocks (???), and physiography (??).rnStratigraphic Systems (????): This section details the local rock layers from the oldest Archaean foundations to the Quaternary loess, specifically focusing on the coal-bearing series of the Western Hills.rnEconomic Geology (????): A significant portion is dedicated to the practical mining of the region, including descriptions of the Men-Tou-Kou (Mentougou) and Chai-Tang coal fields, which were vital to Beijings economy.rnAdministrative Preface: It includes an introduction by the Ministry of Agriculture and Commerce, positioning the work as a landmark in the modern scientific development of China. rnAll the illustrations (15) and figures (16) are presentrn‎
