Ahwas sandstone and Kalhur evaporate members are two main constituents of the best reservoir unit of Zagros region, i.e. Asmari Formation. Poorly cemented to loose nature of the sandstone member and it’s well textural maturity provide highly porous and permeable zones, whereas highly compacted nature of the evaporate member provide impermeable zones in the reservoir. This paper aims to study th...

Estimation and mapping of forest resources are preconditions for management, planning and research. In this study, we applied kriging interpolation of geostatistics for estimation and mapping of forest stock at-tributes in a natural, uneven-aged, unmanaged forest in the Caspian region of northern Iran. The site of the study has an area of 516 ha and an elevation that ranges from 1100 to 1450 m ...
