WARM TO COLD WATER CARBONATE FORMATION DURING THE ORDOVICIAN AND THE JURASSIC: EXAMPLES FROM IRAN, AUSTRALIA, AND ENGLAND [PDF]

Journal of Sciences, Islamic Republic of Iran, 2003
Isotope data from bulk carbonates, micrite, marine calcite cements, non-skeletal grains and brachiopods indicate deposition of a wide spectrum of warm to cold water carbonates during the Ordovician and the Jurassic.

Irrigation Expansion in the US Corn Belt: Patterns and Yield Impacts

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Agricultural irrigation is steadily expanding in the traditionally non‐irrigated US Corn Belt, a globally important region for maize and soybean production. While irrigation boosts crop productivity and buffers yields amid weather variability, its significant consumptive water use has implications for regional hydrology.
