clinopyroxene phenocrysts and microphenocrysts in potassic and sodic eosen alkaline volcanic rocks from the northern lahrud (nw iran) record various stages in the crystallization and evolution history of the alkaline melt as well as its origin. the rock series hosting the clinopyroxene phenocrysts is phonolitic tephrite and tephritic phonolite composition. theses rocks generally show porphyriti...

Lacustrine non-skeletal carbonates exhibit a diversity of petrographies due to interactions between physico-chemical and biologically influenced mechanisms. Despite the suggestion that evaporative concentration was involved in formation spherulite shrubby-bearing carbonate successions Pre-Salt Cretaceous alkaline lakes South Atlantic, no consensus exists about water chemistries promoting these ...

Soil physicochemical properties are the main driving factors affecting stability and diversity of soil microbial community. The impacts saline–alkali situation associated degradation need to be understood reversed as communities increasingly affected by saline–alkaline soil. However, differences between salinization alkalization their impact on microbiota have been overlooked. object this study...

Coastal salt-affected soils account for a large area all around the world. Soil salinity and pH are two important parameters affecting soil quality. Investigating correlation of electrical conductivity (EC) at different depths in saline was useful quickly assessing saline–alkaline characteristics. During natural desalination process field reclaimed lands, phenomena increase nitrogen accumulatio...
