Unravelling the burial-deformation history of sedimentary rocks is prerequisite information to understand the regional tectonic, sedimentary, thermal, and fluid-flow evolution of foreland basins. We use a combination of microstructural analysis, stylolites paleopiezometry, and paleofluid geochemistry to reconstruct the burial-deformation history of the Meso-Cenozoic carbonate sequence of the Cingoli Anticline (Northern Apennines, central Italy). Four major sets of mesostructures were linked to the regional deformation sequence: (i) pre-folding foreland flexure/forebulge; (ii) fold-scale layer-parallel shortening under a N045 σ1; (iii) syn-folding curvature of which the variable trend between the north and the south of the anticline is consistent with the arcuate shape of the anticline; (iv) the late stage of fold tightening. The maximum depth experienced by the strata prior to contraction, up to 1850 m, was quantified by sedimentary stylolite paleopiezometry and projected on the reconstructed burial curve to assess the timing of the contraction. As isotope geochemistry points towards fluid precipitation at thermal equilibrium, the carbonate clumped isotope thermometry (Δ47) considered for each fracture set yields the absolute timing of the development and exhumation of the Cingoli Anticline: layer-parallel shortening occurred from ~6.3 to 5.8 Ma, followed by fold growth that lasted from ~5.8 to 3.9 Ma.

The book is devoted to the International Baikal Drilling Project, a part of the program «Global changes of the environment and climate», accomplished by the Russian, American and Japanese scientists. Much attention is given to the fact that the Baikal Drilling team acted as a single, solid team. The major results obtained from those studies were described in numerous publications published in various Russian and International journals. We hope that the book will be interesting for young scientists, so that they can feel an interest in studying the secrets of nature. The project was accomplished owing to the efforts of M.I. Kuzmin, V.S. Antipin, A.V. Goreglyad, V.F. Geletyi, G.V. Kalmychkov (Institute of Geochemistry, SB RAS), M.A Grachev, O.M. Khlystov (Limnological Institute, SB RAS). Many problems that arouse in the project management were solved with the assistance of V.A. Fialkov, Director of the Baikal Museum, SB RAS, A.A. Bukharov, Vive-Director of the Baikal Museum, and the translators T. V. Bunaeva and M. Yu. Khomutova. The book not only describes a difficult work in the ice of Lake Baikal, but also presents the valuable data on the mineral composition of the bottom sediments, the discovery of Baikal gas hydrates, and the evolution of the landscapes and climate of the Baikal region in the Late Cenozoic. Modern methods of electron-probe x-ray spectral microanalysis and isotope geochemistry are described in detail. All this, as well as the methods of modeling real mineral associations, make this book valuable for researchers in different fields of science.
