Tectonics, Volume 43, Issue 7, July 2024.Abstract Calabria and the Peloritan Mts. of NE Sicily are exotic terranes predominantly formed by Hercynian rocks interrupting the Meso‐Cenozoic sediments exposed along Apennine‐Maghrebide chains. Dual‐polarity pre‐tilting magnetization direction retrieved from 5 Jurassic, 5 upper Cretaceous‐Eocene, and 4 upper Oligocene sedimentary sites from external‐

European Journal of Organic Chemistry, Volume 27, Issue 7, February 19, 2024.Flexible bis‐catecholate podand‐type ligands of various lengths were synthesized. Upon reaction with boric acid and a hydroxide alkaline solution, a spiroborate node forms and the alkali cation is wrapped by the flexible spacer. Influence of the spacer's length and the alkali cation size on the formation of monomeric or oligomeric spiroborate compounds

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 1, January 2024.Abstract In southern Africa, the Okavango Delta is a large alluvial fan sustaining a unique wetlands ecosystem in the heart of the Kalahari desert. The Delta is fed by an annual flood that brings water from the Angolan plateaus to the north, down to the Okavango region.

Bulletin of the Mineral Research and Exploration, 1978 Deux soubassements paleozoiques differents et non correlables stratigraphiquement sont juxtaposes dans la coupole de Karacahisar. Le double accident tectonique qui les separe actuellement s'amortit lateralement dans la couverture mesozoique commune qui ...
